February 10 in History

The Siege of Baghdad, also known as the Sack of Baghdad, took place in early 1258. A large army commanded by Hulegu, a prince of the Mongol Empire, attacked the historic capital of the Abbasid Caliphate after a series of provocations from its ruler, caliph al-Musta'sim. Within a few weeks, Baghdad fell and was sacked by the Mongol army—al-Musta'sim was killed alongside hundreds of thousands of his subjects. The city's fall has traditionally been seen as marking the end of the Islamic Golden Age; in reality, its ramifications are uncertain. After the accession of his brother Möngke Khan to the Mongol throne in 1251, Hulegu, a grandson of Genghis Khan, was dispatched westwards to Persia to secure the region. His massive army of over 138,000 men took years to reach the region but then quickly attacked and overpowered the Nizari Ismaili Assassins in 1256. The Mongols had expected al-Musta'sim to provide reinforcements for their army—the Caliph's failure to do so, combined with his arrogance in negotiations, convinced Hulegu to overthrow him in late 1257. Invading Mesopotamia from all sides, the Mongol army soon approached Baghdad, routing a sortie on 17 January 1258 by flooding their opponents' camp. They then invested Baghdad, which was left with around 30,000 troops. The assault began at the end of January. Mongol siege engines breached Baghdad's fortifications within a couple of days, and Hulegu's highly-trained troops controlled the eastern wall by 4 February. The increasingly desperate al-Musta'sim frantically tried to negotiate, but Hulegu was intent on total victory, even killing soldiers who attempted to surrender. The Caliph eventually surrendered the city on 10 February, and the Mongols began looting three days later. The total number of people who died is unknown, as it was likely increased by subsequent epidemics; Hulegu later estimated the total at around 200,000. After calling an amnesty for the pillaging on 20 February, Hulegu executed the caliph. In contrast to the exaggerations of later Muslim historians, Baghdad prospered under Hulegu's Ilkhanate, although it did decline in comparison to the new capital, Tabriz.

Dumfries ( dum-FREESS; from Scottish Gaelic: Dùn Phris [ˌt̪un ˈfɾʲiʃ]) is a market town and former royal burgh in Dumfries and Galloway, Scotland, near the mouth of the River Nith on the Solway Firth, 25 miles (40 km) from the Anglo-Scottish border. Dumfries is the county town of the historic county of Dumfriesshire. Before becoming King of Scots, Robert the Bruce killed his rival John Comyn III of Badenoch at Greyfriars Kirk in the town in 1306. The Young Pretender had his headquarters here towards the end of 1745. In World War II, the Norwegian armed forces in exile in Britain largely consisted of a brigade in Dumfries. Dumfries is nicknamed Queen of the South; this is also the name of the town's football club. People from Dumfries are known colloquially in Scots language as Doonhamers.

The St Scholastica Day riot began in Oxford, England, on 10 February 1355, the feast day of St Scholastica. The disturbance began when two students from the University of Oxford complained about the quality of wine served to them in the Swindlestock Tavern, which stood at the crossroads now known as Carfax, in the centre of the town. The students quarrelled with the taverner; the argument quickly escalated to blows. The inn's customers joined in on both sides, and the resulting mêlée turned into a riot. The violence started by the bar brawl continued over three days, with armed gangs entering the town from the countryside to assist the townspeople. University halls and students' accommodation were raided and the inhabitants murdered; there were some reports of scholars being scalped. Around twenty townsfolk were killed, as were up to sixty-three members of the university. Violent disagreements between townspeople and students had arisen several times previously, and twelve of the twenty-nine coroners' courts held in Oxford between 1297 and 1322 concerned murders by students. The University of Cambridge was established in 1209 by scholars who left Oxford following the lynching of two students by the town's citizens. King Edward III sent judges to the town with commissions of oyer and terminer to determine what had gone on and to advise what steps should be taken. He came down on the side of the university authorities, who were given additional powers and responsibilities to the disadvantage of the town's authorities. The town was fined 500 marks and its mayor and bailiffs were sent to the Marshalsea prison in London. John Gynwell, the Bishop of Lincoln, imposed an interdict on the town for one year, which banned all religious practices, including services (except on key feast days), burials and marriages; only baptisms of young children were allowed. An annual penance was imposed on the town: each year, on St Scholastica's Day, the mayor, bailiffs and sixty townspeople were to attend a Mass at the University Church of St Mary the Virgin for those killed; the town was also made to pay the university an annual fine of one penny for each scholar killed. The practice was dropped in 1825; in 1955—the 600th anniversary of the riots—in an act of conciliation the city's mayor was given an honorary degree, while the university's vice-chancellor was made an honorary freeman of the city.

Manuel II Palaiologos or Palaeologus (Greek: Μανουὴλ Παλαιολόγος, romanized: Manouḗl Palaiológos, pronounced [ma.nuˈil pa.le.oˈlo.ɣos]; 27 June 1350 – 21 July 1425) was Byzantine emperor from 1391 to 1425. Shortly before his death he was tonsured a monk and received the name Matthaios (Ματθαίος). Manuel was a vassal of the Ottoman Empire, which sometimes threatened to capture his territory outright. Accordingly he continued his father's practice of soliciting Western European aid against the Ottomans, and personally visited several foreign courts to plead his cause. These efforts failed, although an Ottoman civil war and Byzantine victories against Latin neighbors helped Manuel's government survive and slightly expand its influence. His wife Helena Dragaš saw to it that their sons, John VIII and Constantine XI, became emperors. He is commemorated by the Greek Orthodox Church on 21 July.

Vasco da Gama was a Portuguese mariner, explorer and nobleman. His discovery of the first maritime route between Europe and India—around the Cape of Good Hope, then across the Indian Ocean from Malindi in Kenya to Kozhikode—opened up European exploration of, and commerce with, India, and is considered a landmark event in world history.

Henry Stuart, Lord Darnley (1546 – 10 February 1567) was King of Scotland as the second husband of Mary, Queen of Scots, from 29 July 1565 until his murder. Darnley had one child with Mary, James VI of Scotland and I of England. Less than a year after the birth of his son, Darnley was murdered at Kirk o' Field in 1567. Many contemporary narratives describing his life and death refer to him as simply Lord Darnley, his title as heir apparent to the Earldom of Lennox.

The Huilliche uprising of 1712 (Spanish: Rebelión huilliche de 1712) was an Indigenous uprising against the Spanish encomenderos of the Chiloé Archipelago, which was then a part of the Captaincy General of Chile. The rebellion took place in the central part of the archipelago.

The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon. The wars originated in political forces arising from the French Revolution (1789–1799) and French Revolutionary Wars (1792–1802) and produced a period of French domination over continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia. The first stage of the wars broke out when Britain declared war on France on 18 May 1803. After minor campaigns, Britain allied with Austria, Russia, and minor powers, to form the Third Coalition in April 1805. Napoleon defeated the allied Russo-Austrian armies in the subsequent war which climaxed in French victories at Ulm and at Austerlitz, leading to the dissolution of the Holy Roman Empire and Austria being forced to make peace. Britain and Russia remained at war with France. Concerned about increasing French power, Prussia joined Britain and Russia in the Fourth Coalition, which resumed war in October 1806. Napoleon defeated the Prussians at Jena-Auerstedt and the Russians at Friedland, bringing an uneasy peace to the continent by July 1807, and again leaving Britain as France's sole major enemy. Britain was unable to dispute French dominance on the continent but obtained hegemony over the seas after victories including Trafalgar. Russia used the interim peace to resolve wars with the Ottomans, Swedes, and Iranians. Hoping to isolate and weaken Britain economically through his Continental System, Napoleon launched an invasion of Portugal, the only remaining British ally in continental Europe. After occupying Lisbon in November 1807, and with the bulk of French troops present in Spain, Napoleon seized the opportunity to turn against his former ally, depose the reigning Spanish royal family, and declare his brother as Joseph I the King of Spain in 1808, to the disapproval of the Spanish populace. Spain joined Britain and Portugal, with the three powers engaging France in the Peninsular War. The diversion of French armies to the large new Anglo-Spanish front led to Austria reentering the conflict and forming the Fifth Coalition in April 1809, composed of Austria, Spain, and Britain. Austria won the Battle of Aspern-Essling but was defeated at Wagram, forcing the imposition of a harsh peace in October 1809. Britain, Spain, and Portugal remained at war with France. Concurrently Russia, unwilling to bear the economic consequences of reduced trade, violated the Continental System, prompting Napoleon to launch an invasion in June 1812. The resulting campaign was costly for both sides, but ultimately ended in disaster for France and the near-destruction of Napoleon's Grande Armée. French forces retreated from Russia by December 1812 and began reconstituting their lost strength. Encouraged by the defeat, Austria, Prussia, and several minor powers joined Russia, Britain, and Spain in a Sixth Coalition and began a campaign against France. The Sixth Coalition defeated Napoleon at Leipzig in October 1813. The allies then invaded France on two fronts: the Russians, Austrians, and Prussians invaded France from the east, while the British, Spanish, and Portuguese invaded France from the west. Coalition troops captured Paris in March 1814, forced Napoleon to abdicate in April, exiled him to the island of Elba, and restored power to the Bourbons. Napoleon escaped exile in February 1815 and reassumed control of France for around one hundred days, igniting the eponymous conflict. The allies formed the Seventh Coalition, which defeated him at Waterloo in June 1815 and exiled him to Saint Helena, where he died in 1821. The wars had profound consequences on history. New methods of warfare were introduced, including mass conscription and guerrilla warfare. Politically, the wars greatly influenced Europe through the advancements in civil law brought about by the Napoleonic Code, which was largely retained where it was adopted, and the spread of nationalism and liberalism. Independence movements emerged in Spanish America as a direct consequence of the wars, leading to the decline of the Spanish and Portuguese Empires. France's defeat led to the rise of Britain as the world's foremost naval and economic power, a status it would hold for the remainder of the century. After the end of the Napoleonic Wars, the Congress of Vienna redrew Europe's borders and brought a relative peace to the continent, with no major great power conflicts until the Crimean War in 1853.

Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death in 1901. Her reign of 63 years and 216 days, which was longer than those of any of her predecessors, constituted the Victorian era, a period of industrial, political, scientific, and military change within the United Kingdom marked by a great expansion of the British Empire. In 1876, the British parliament voted to grant her the additional title of Empress of India. Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn, who was the fourth son of King George III. After the deaths of her father and grandfather in 1820, she was raised under close supervision by her mother, Princess Victoria of Saxe-Coburg-Saalfeld, and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Victoria attempted privately to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality. Victoria married her maternal first cousin, Prince Albert of Saxe-Coburg and Gotha, in 1840. Their nine children married into royal and noble families across the continent, earning Victoria the sobriquet "grandmother of Europe". After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, British republicanism temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond jubilees were times of public celebration. Victoria died at Osborne House on the Isle of Wight, at the age of 81. The last British monarch of the House of Hanover, she was succeeded by her son Edward VII.

The First Anglo-Sikh War was fought between the Sikh Empire and the British Empire from 1845 to 1846 around the Firozpur district of Punjab. It resulted in the defeat and partial subjugation of the Sikh Empire and cession of Jammu and Kashmir as a separate princely state under British suzerainty.

Jefferson F. Davis (June 3, 1808 – December 6, 1889) was the only president of the Confederate States from 1861 to 1865, leading the Confederacy during the American Civil War. Before the war, he was a member of the Democratic Party who represented Mississippi in the House of Representatives from 1845 to 1846 and in the United States Senate from 1857 to 1861. From 1853 to 1857, he served as the 23rd United States secretary of war during the administration of President Franklin Pierce. Davis, the youngest of ten children, was born in Fairview, Kentucky, but spent most of his childhood in Wilkinson County, Mississippi. His eldest brother, Joseph Emory Davis, secured the younger Davis's appointment to the United States Military Academy. Upon graduating, he served six years as a lieutenant in the United States Army. After leaving the army in 1835, Davis married Sarah Knox Taylor, daughter of future president Zachary Taylor. Sarah died from malaria three months after the wedding. Davis became a cotton planter, building Brierfield Plantation in Mississippi on his brother Joseph's land and eventually owning as many as 113 slaves. In 1845, Davis married Varina Howell. During the same year, he was elected to the United States House of Representatives, serving for one year. From 1846 to 1847, he fought in the Mexican–American War as the colonel of a volunteer regiment. He was appointed to the United States Senate in 1847, resigning to unsuccessfully run for governor of Mississippi. In 1853, President Franklin Pierce appointed him Secretary of War. After Pierce's administration ended in 1857, Davis returned to the Senate. He resigned in 1861 when Mississippi seceded from the United States. During the Civil War, Davis guided the Confederacy's policies and served as its commander in chief. When the Confederacy was defeated in 1865, Davis was captured, arrested for alleged complicity in the assassination of Abraham Lincoln, accused of treason, and imprisoned at Fort Monroe. He was released without trial after two years. Immediately after the war, Davis was often blamed for the Confederacy's defeat, but after his release from prison, the Lost Cause of the Confederacy movement considered him to be a hero. In the late 19th and the 20th centuries, his legacy as a Confederate leader was celebrated in the South. In the 21st century, his leadership of the Confederacy has been seen as constituting treason, and he has been frequently criticized as a supporter of slavery and racism. Many of the memorials dedicated to him throughout the United States have been removed.

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans. Decades of controversy over slavery came to a head when Abraham Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven slave states in the South responded to Lincoln's victory by seceding from the United States and forming the Confederate States of America. The Confederacy seized US forts and other federal assets in the South. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis, the Confederacy comprised eleven states, containing a third of the US population. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in the western theater, the Union made permanent gains, though in the eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued the Emancipation Proclamation, which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed the Confederacy's river navy by the summer of 1862, then much of its western armies, and seized New Orleans. The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River, while Confederate general Robert E. Lee's incursion north failed at the Battle of Gettysburg. General Ulysses S. Grant's western successes led Lincoln to promote him to command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union general William Tecumseh Sherman, followed by his March to the Sea, which culminated in his taking Savannah. The last significant battles raged around the ten-month siege of Petersburg, gateway to the Confederate capital of Richmond. The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House, setting in motion the end of the war. Lincoln lived to see this victory but was shot by an assassin on April 14, dying the next day. By the end of the war, much of the South's infrastructure had been destroyed. The Confederacy collapsed, the Thirteenth Amendment abolished slavery, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, bring the former Confederate states back into the United States, and grant civil rights to freed slaves. The war is one of the most extensively studied and written about episodes in the history of the United States. It remains the subject of cultural and historiographical debate. Of continuing interest is the myth of the Lost Cause of the Confederacy. The war was among the first to use industrial warfare. Railroads, the electrical telegraph, steamships, the ironclad warship, and mass-produced weapons were widely used. The war left an estimated 700,000 soldiers dead, along with an undetermined number of civilian deaths, making it the deadliest in American history. The technology and brutality of the Civil War foreshadowed the coming world wars.

HMS Dreadnought was a Royal Navy battleship, the design of which revolutionised naval power. The ship's entry into service in 1906 represented such an advance in naval technology that her name came to be associated with an entire generation of battleships, the dreadnoughts, as well as the class of ships named after her. Likewise, the generation of ships she made obsolete became known as pre-dreadnoughts. Admiral Sir John "Jacky" Fisher, First Sea Lord of the Board of Admiralty, is credited as the father of Dreadnought. Shortly after he assumed office in 1904, he ordered design studies for a battleship armed solely with 12 in (305 mm) guns and a speed of 21 knots (39 km/h; 24 mph). He convened a Committee on Designs to evaluate the alternative designs and to assist in the detailed design work. Dreadnought was the first battleship of her era to have a uniform main battery, rather than having a few large guns complemented by a heavy secondary armament of smaller guns. She was also the first capital ship to be powered by steam turbines, making her the fastest battleship in the world at the time of her completion. Her launch helped spark a naval arms race as navies around the world, particularly the Imperial German Navy, rushed to match it in the build-up to the First World War. Although designed to engage enemy battleships, her only significant action was the ramming and sinking of German submarine SM U-29; thus she became the only battleship confirmed to have sunk a submarine. Dreadnought did not participate in the Battle of Jutland in 1916 as she was being refitted, nor did she participate in any of the other naval battles in World War I. In July 1916 she was relegated to coastal-defence duties in the English Channel, before rejoining the Grand Fleet in 1918. The ship was reduced to reserve in 1919 and sold for scrap two years later.

Józef Haller von Hallenburg (or de Hallenburg; Polish pronunciation: [/ˈju.zɛf ˈxal.lɛr/]; 13 August 1873 – 4 June 1960) was a Polish lieutenant general and legionary in the Polish Legions during the First World War. He was a harcmistrz (the highest Scouting instructor rank in Poland), the president of the Polish Scouting and Guiding Association (ZHP), and a political and social activist. He was also the cousin of Stanisław Haller. Haller was born in Jurczyce. He studied at Vienna's Technical Military Academy and subsequently (1895–1906) served with the Austrian Army, resigning after reaching the rank of captain. He supported the paramilitary pro-independence Polish organization Sokół. In 1916, during the First World War, he became commander of the Second Brigade of the Polish Legion, in particular the units which fought against Russia on the Eastern Front. In 1918, in the aftermath of the "Charge at Rarańcza", as commander of the 2nd Polish Auxiliary Corps with the Austrian Army, Haller broke through the Austro-Russian front line to Ukraine, where he united his troops with Polish detachments which had left the Tsarist army. He protested the Treaty of Brest-Litovsk and continued to fight the Russians with his II Brigade of the Polish Legions (later, the 4th and 5th Rifle Divisions of the Polish II Corps). Under the pressure of the Germans, who after the Peace of Brest-Litovsk regarded the presence of Polish troops in Ukraine as illegal, and a fierce battle between Poles and Germans at Kaniów (10 May 1918, 2500 casualties) his corps was interned, while the Brigadier himself managed to escape to Moscow. Subsequently, by the way of Murmansk, he arrived in France in July 1918, where on behalf of the Polish National Committee he created what was known as the Blue Army (from the color of its French uniforms, also known as Haller's Army). For the next few months his army, allied to the Entente, would fight against Germany. In 1919, at the new army's head, he arrived in Poland and was dispatched to the Ukrainian front. During the Polish-Soviet War he commanded an army of volunteers. He was also Inspector General of the Army and a member of the War Council. In 1920–1927 Haller was a deputy to the Sejm. After the election of Gabriel Narutowicz as President of the Republic in December 1922, Haller fell into disfavor. After the 1926 May Coup, he was ordered into retirement. He co-organized an opposition party, the "Front Morges". At the time of the invasion of Poland (1939), Haller was living abroad. From 1940 to 1943 he served as Minister of Education in Władysław Sikorski's government. After 1945 he settled in London as an exile and did not take active part in any émigré Polish political activities.

Denmark is a Nordic country in Northern Europe. It is the metropole and most populous constituent of the Kingdom of Denmark, also known as the Danish Realm, a constitutionally unitary state that includes the autonomous territories of the Faroe Islands and Greenland in the north Atlantic Ocean. Metropolitan Denmark, also called "continental Denmark" or "Denmark proper", consists of the northern Jutland peninsula and an archipelago of 406 islands. It is the southernmost of the Scandinavian countries, lying southwest of Sweden, south of Norway, and north of Germany, with which it shares a short border. Metropolitan Denmark is situated between the North Sea to the west and the Baltic Sea to the east.

Texas Tech University (Texas Tech, TTU, or simply Tech) is a public research university in Lubbock, Texas, United States. Established in 1923 and called Texas Technological College until 1969, it is the flagship institution of the five-institution Texas Tech University System. As of fall 2025, the university enrolled 42,455 students, making it the sixth-largest university in Texas. The university offers degrees in more than 150 courses of study through 13 colleges and hosts 55 research centers and institutes. Texas Tech University has awarded nearly 325,000 degrees since 1927, including over 75,000 graduate and professional degrees. It is classified among "R1: Doctoral Universities – Very high research activity". Research projects in the areas of pulsed power, strengthening national security, grid computing, resilience and adaptability, energy, advancing One Health, rural and urban development, and atmospheric sciences are among the most prominent at the university. The Institute for Critical Infrastructure Security works to solve the continuous problem of cyber-security interruptions in critical infrastructure systems. The Institute for One Health Innovation is composed of experts in human, animal and environmental health to better understand how each interacts with the others, and thereby develop a more holistic approach to health for all. Beginning in 2025 under the chancellorship of Brandon Creighton, the university has attracted controversy and national attention owing to its widespread censorship of topics viewed as left-wing and mandated ideological review of course materials. The Texas Tech Red Raiders are charter members of the Big 12 Conference and compete in Division I for all varsity sports. The Red Raiders football team has made 41 bowl appearances, which is tied for 20th most of any university. The Lady Raiders basketball team won the 1993 NCAA Division I Tournament.

The Việt Nam Quốc Dân Đảng, also known as the Vietnamese Nationalist Party and abbreviated VNQDĐ, was a nationalist and democratic socialist political group that sought independence from French colonial rule in Vietnam during the early 20th century. Its origins lie in a group of young Hanoi-based intellectuals who began publishing revolutionary material in the mid-1920s. In 1927, after the publishing house failed because of French harassment and censorship, the VNQDĐ was formed under the leadership of Nguyễn Thái Học. Modelling itself on the Kuomintang of Nationalist China the VNQDĐ gained a small following among northerners, particularly teachers and intellectuals. The party, which was less successful among peasants and industrial workers, was organised in small clandestine cells.

Boxing is a combat sport and martial art. Taking place in a boxing ring, it involves two opponents throwing punches at each other for a predetermined amount of time. It is usually done wearing protective equipment, such as protective gloves, hand wraps, and mouthguards.

The Second Italo-Ethiopian War, also referred to as the Second Italo-Abyssinian War, was a war of aggression waged by Italy against Ethiopia, which lasted from October 1935 to May 1936. In Ethiopia it is often referred to simply as the Italian Invasion (Amharic: ጣልያን ወረራ, romanized: Ṭalyan warära), and in Italy as the Ethiopian War (Italian: Guerra d'Etiopia). The war is regarded as the largest colonial campaign in history. On 3 October 1935, two hundred thousand soldiers of the Regio Esercito (Royal Army) commanded by Marshal Emilio De Bono attacked from Italian Eritrea without prior declaration of war. At the same time a smaller force under General Rodolfo Graziani attacked from Italian Somalia. On 6 October, Adwa was conquered, a symbolic place for the Italian army as it was the site of their defeat at the Battle of Adwa during the First Italo-Ethiopian War. On 15 October, Italian troops seized the town of Aksum, and its famous obelisk was torn from its site and sent to Rome to be placed symbolically in front of the building of the Ministry of Colonies. Exasperated by De Bono's slow and cautious progress, Benito Mussolini replaced him with General Pietro Badoglio. Ethiopian forces launched a counterattack in December 1935 that achieved some gains and temporarily halted the Italian advance. Frustrated, Mussolini authorized the use of mustard gas, with the Regia Aeronautica (Royal Air Force) dropping 330 tons over the next four months, violating the 1925 Geneva Protocol. The Italians resumed the offensive in early February, decisively defeating the Ethiopian army at Amba Aradam, Tembien, and Shire. On 31 March 1936, the Italians won a decisive victory at the Battle of Maychew, which nullified any possible organized Ethiopian resistance. Emperor Haile Selassie was forced to flee into exile on 2 May, and Badoglio's forces arrived in the capital Addis Ababa on 5 May. Mussolini then announced the annexation of Ethiopia on 9 May and the colony of Italian East Africa was formed. Hostilities did not cease with the end of conventional war operations and Ethiopian resistance to Italian rule would continue until the country was liberated in 1941. Overall, the war in Ethiopia was a major military success for the fascist regime in Italy, achieved relatively quickly and with considerable propaganda value. However, it also placed a significant strain on an already seriously unbalanced budget, weakening Italy's long-term economic position. The Italian aggression against Ethiopia had significant diplomatic consequences, leading to the end of the Stresa Front and Italy's rapprochement with Nazi Germany. Simultaneously, the inability of the League of Nations to prevent the invasion discredited it internationally on the eve of the Second World War. Italian troops used mustard gas in aerial bombardments (in violation of the Geneva Protocol and Geneva Conventions) against combatants and civilians in an attempt to suppress Ethiopian resistance. Deliberate Italian attacks against ambulances and hospitals of the Red Cross were reported. By all estimates, hundreds of thousands of Ethiopian civilians died as a result of the Italian invasion, which have been described by some historians as constituting genocide. Crimes by Ethiopian troops included the use of dumdum bullets (in violation of the Hague Conventions), the killing of civilian workmen (including during the Gondrand massacre) and the mutilation of captured Eritrean Ascari and Italians (often with castration).

The Spanish Civil War (Spanish: guerra civil española) was fought in Spain from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists, who established the military-led Spanish State and were directly aided by an intervention from Fascist Italy and participation of Nazi Germany. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or communism and fascism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975. The war began after the partial failure of the coup d'état of July 1936 against the Popular Front government by a group of generals of the Spanish Republican Armed Forces. They were supported by right-wing groups including the Christian traditionalist party CEDA; monarchists, including both the opposing Alfonsists and the religious conservative Carlists; and the Falange Española de las JONS, a fascist political party. However, rebelling units in almost all important cities did not gain control, leaving Spain militarily and politically divided. The Nationalists were initially led by a military junta, until General Francisco Franco was appointed supreme leader on 1 October 1936 of what he called the Spanish State. The rebellion was countered by the arming of left-wing social movements and parties, and the formation of militias. This led to rapid socioeconomic and political transformation in the Republican zone, referred to as the Spanish Revolution. The Nationalist forces received munitions, soldiers, and air support from Fascist Italy which conducted a large-scale intervention and Nazi Germany which sent its Condor Legion, while the Republican government received support from the Soviet Union and Mexico. Other countries, such as the United Kingdom, France, and the United States, continued to recognise the Republican government, but followed official policies of non-intervention. Despite this, tens of thousands of citizens from non-interventionist countries directly participated in the conflict, mostly in the pro-Republican International Brigades. Franco gradually emerged as the primary leader of the Nationalists, becoming the dictator of the Spanish State by 1937 and co-opting Falangism, gaining recognition as a fascist leader. The Nationalists advanced from their strongholds in the south and west, capturing most of Spain's northern coastline in 1937 and besieging Madrid. After much of Catalonia was captured in 1938 and 1939 and Madrid was cut off from Barcelona, the Republican military position became hopeless. On 5 March 1939, in response to allegedly increasing communist dominance of the Republican government and the deteriorating military situation, Colonel Segismundo Casado led a military coup against the Republican government, intending to seek peace with the Nationalists. These peace overtures, however, were rejected by Franco. Following internal conflict between Republican factions in Madrid in the same month, Franco entered the capital and declared victory on 1 April 1939. Hundreds of thousands of those associated with the Republicans fled Spain, mostly to refugee camps in southern France; many of those who stayed were persecuted by the victorious Nationalists. The war became notable for the passion and political division it inspired worldwide, and for the many atrocities that occurred. Organised purges occurred in territory captured by Franco's forces to consolidate power. Mass executions took place in areas controlled by the Republicans, with the participation of local authorities varying by location.

The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a transcontinental country that spanned much of Eurasia from its formation in 1922 until its dissolution in 1991. It was the world's third-most populous country, the largest by area, and bordered twelve other countries. A diverse multinational state, it was organized as a federal union of national republics, with the largest and most populous being the Russian Soviet Federative Socialist Republic (SFSR). The world's flagship communist state, it was governed by the Communist Party under Marxism–Leninism, through soviet councils. The Soviet economy was also centrally planned. Its capital and largest city was Moscow.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many engaging in total war on an unprecedented scale. World War II was the deadliest conflict in history, causing the deaths of 60 to 75 million people, a majority of whom were civilians. Millions died as a result of massacres, starvation, disease, and genocides including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Paris Peace Treaties (French: Traités de Paris) were signed on 10 February 1947 following the end of World War II in 1945. The Paris Peace Conference lasted from 29 July until 15 October 1946. The victorious wartime Allied powers (principally the United Kingdom, Soviet Union, United States, and France) negotiated the details of peace treaties with the former (mostly minor) European Rome-Berlin-Tokyo Axis powers, namely Italy, Romania, Hungary, Bulgaria, and Finland. They were allowed to fully resume their responsibilities as sovereign states in international affairs and to qualify for membership in the United Nations. The settlement elaborated in the peace treaties included payment of war reparations, commitment to minority rights, and territorial adjustments including the end of the Italian colonial empire in North Africa, East Africa, Yugoslavia, Greece, and Albania, as well as changes to the Italian–Yugoslav, Hungarian–Czechoslovak, Soviet–Romanian, Hungarian–Romanian, French–Italian, and Soviet–Finnish borders. The treaties also obliged the various states to hand over accused war criminals to the Allied powers for war crimes trials.

Dwight David "Ike" Eisenhower (born David Dwight Eisenhower; October 14, 1890 – March 28, 1969) was the 34th president of the United States, serving from 1953 to 1961. In his previous military career, he commanded the Allied Expeditionary Force during World War II, including in Operation Torch in North Africa and Operation Overlord on D-Day in Normandy. For his distinguished service in the U.S. Army, Eisenhower was honored with the five-star rank of General of the Army. Eisenhower graduated from West Point in 1915. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Between the wars he served in staff positions in the US and the Philippines, reaching the rank of brigadier general shortly before the entry of the US into World War II in 1941. After further promotion Eisenhower oversaw the Allied invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war ended in Europe, he served as military governor of the American-occupied zone of Germany (1945), as Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952). In 1952, Eisenhower entered the presidential race as a Republican, in part to block the presidential prospects of Senator Robert A. Taft, who opposed NATO and sought to undo the New Deal. Eisenhower won that year's election and the 1956 election in landslides, both times defeating Adlai Stevenson II. Eisenhower's main goals in office were to contain the spread of communism and reduce federal deficits. In 1953, Eisenhower considered using nuclear weapons to end the Korean War and may have threatened China with nuclear attack if an armistice was not reached quickly. China did agree and an armistice resulted, which remains in effect. His New Look policy of nuclear deterrence prioritized "inexpensive" nuclear weapons while reducing funding for expensive Army divisions. He continued Harry S. Truman's policy of recognizing Taiwan as the legitimate government of China, and he won congressional approval of the Formosa Resolution. His administration provided aid to help the French try to fight Vietnamese Communists in the First Indochina War. After the French left, he gave strong financial support to the new state of South Vietnam. Eisenhower supported regime-changing military coups in Iran and Guatemala orchestrated by his own administration. During the Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. He deployed 15,000 soldiers during the 1958 Lebanon crisis. Near the end of his term, a summit meeting with the Soviet leader Nikita Khrushchev was cancelled when a US spy plane was shot down over the Soviet Union. Eisenhower approved the Bay of Pigs Invasion, which was left to John F. Kennedy to carry out. Eisenhower continued New Deal agencies and expanded Social Security. He covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking executive privilege. He signed the Civil Rights Act of 1957 and sent Army troops to enforce federal court orders which integrated schools in Little Rock, Arkansas. His administration undertook the development and construction of the Interstate Highway System, which remains the largest construction of roadways in American history. In 1957, following the Soviet launch of Sputnik, Eisenhower led the American response which included the creation of NASA and the establishment of a stronger, science-based education via the National Defense Education Act. The Soviet Union began to reinforce their own space program, escalating the Space Race. His two terms saw unprecedented economic prosperity except for a minor recession in 1958. In his farewell address, he expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, which he dubbed "the military–industrial complex". Historical evaluations of his presidency place him among the upper tier of US presidents.

The Cold War was a period of international geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc. It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

The Twenty-fifth Amendment (Amendment XXV) to the United States Constitution addresses issues related to presidential succession and disability. It clarifies that the vice president becomes president if the president dies, resigns, or is removed from office by impeachment. It also establishes the procedure for filling a vacancy in the office of the vice president. The amendment provides for the temporary transfer of the president's powers and duties to the vice president, either on the president's initiative alone or on the initiative of the vice president, together with a majority of the president's cabinet. In either case, the vice president becomes the acting president until the president's powers and duties are restored. The amendment was submitted to the states on July 6, 1965, by the 89th Congress, and was adopted on February 10, 1967, the day the requisite number of states (38) ratified it.

The North Atlantic Treaty Organization (NATO) is an intergovernmental military alliance between 32 member states. Founded in the aftermath of World War II, NATO was established with the signing of the North Atlantic Treaty in 1949. The organization serves as a system of collective security and deterrence, whereby its independent members agree to defend each-other from attack by any outside party. This is enshrined in Article 5 of the treaty, which states that an armed attack against the territory of one member shall be considered an attack against them all.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Some communications satellites are in geostationary orbit 22,236 miles (35,785 km) above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. However, most form satellite constellations in low Earth orbit, where ground antennas must track the satellites and switch between them frequently.

In February 2021, the state of Texas suffered a major power crisis, which came about during three severe winter storms sweeping across the United States on February 10–11, 13–17, and 15–20. The storms triggered the worst energy infrastructure failure in Texas state history, leading to shortages of water, food, and heat. More than 4.5 million homes and businesses were left without power, some for several days. At least 246 people were killed directly or indirectly, with some estimates as high as 702 killed as a result of the crisis.
