June 28 in History

The First Crusade (1096–1099) was the first of a series of religious wars, or Crusades, which were initiated, supported and at times directed by the Latin Church in the Middle Ages. Their aim was to return the Holy Land to Christian rule after its conquest by the Rashidun Caliphate in the 7th century. By the 11th century, although Jerusalem had then been ruled by Muslims for hundreds of years, the practices of the Seljuk rulers in the region began to threaten local Christian populations, pilgrimages from the West, and the Byzantine Empire itself. The earliest impetus for the First Crusade came in 1095 when Byzantine emperor Alexios I Komnenos sent ambassadors to the Council of Piacenza to request military support in the empire's conflict with the Seljuk-led Turks. This was followed later in the year by the Council of Clermont, at which Pope Urban II gave a speech supporting the Byzantine request and urging faithful Christians to undertake an armed pilgrimage to Jerusalem.

Edward IV (28 April 1442 – 9 April 1483) was King of England from 4 March 1461 to 3 October 1470, then again from 11 April 1471 until he died in 1483. A member of the House of York, he was a central figure in the Wars of the Roses, a series of civil wars in England fought between the Yorkist and Lancastrian factions between 1455 and 1487. Edward inherited the Yorkist claim to the throne at the age of eighteen when his father, Richard, Duke of York, was killed at the Battle of Wakefield in December 1460. After defeating Lancastrian armies at Mortimer's Cross and Towton in early 1461, he deposed King Henry VI and took the throne. His marriage to Elizabeth Woodville in 1464 led to conflict with his chief advisor, Richard Neville, Earl of Warwick, known as the "Kingmaker". In 1470, a revolt led by Warwick and Edward's brother George, Duke of Clarence, briefly re-instated Henry VI. Edward fled to Flanders, where he gathered support and invaded England in March 1471; after victories at the battles of Barnet (where the Earl of Warwick was killed) and Tewkesbury (where Henry VI's son, Edward of Westminster, Prince of Wales, was killed), he resumed the throne. Shortly afterwards, Henry VI was found dead in the Tower of London, possibly killed on Edward's orders. Despite facing an overseas threat from Henry Tudor, the last remaining Lancastrian claimant, Edward reigned in relative peace for the next twelve years. However, he nearly restarted the Hundred Years' War, following his invasion of France in 1475, but was assuaged by Louis XI in the Treaty of Picquigny. This diplomatic agreement formally ended the Hundred Years' War, which had been in abeyance since 1453. Following his sudden death in April 1483, Edward was briefly succeeded by his son Edward V. He had appointed his younger brother, Richard, Duke of Gloucester, Lord Protector of England for the duration of the new king's minority. However, Edward V and his younger brother Richard, Duke of York, disappeared shortly after and their uncle seized the throne as Richard III.

The Battle of Seminara, part of the First Italian War, was fought in Calabria on 28 June 1495 between a French garrison in recently conquered Southern Italy and the allied forces of Spain and Naples which were attempting to reconquer these territories. Against the redoubtable combination of gendarmes and Swiss mercenary pikemen in the French force, the allies had only Neapolitan troops of indifferent quality and a small corps of lightly armed Spanish soldiers, accustomed to fighting the Moors of Spain. The result was a rout, and much of the fighting centered on delaying actions to permit the fleeing allied force to escape. The battle is notable primarily because it is often cited as the prime reason for the reorganization of the Spanish army, which brought about widespread adoption of firearms in pike and shot formations, one of the milestones of the "Military Revolution."

Charles V (24 February 1500 – 21 September 1558) was Holy Roman Emperor and Archduke of Austria from 1519 to 1556, King of Spain (as Charles I) from 1516 to 1556, King of Sicily and Naples from 1516 to 1554, and also Lord of the Netherlands and titular Duke of Burgundy (as Charles II) from 1506 to 1555. He was heir to and then head of the rising House of Habsburg. His dominions in Europe included the Holy Roman Empire, extending from Germany to northern Italy with rule over the Austrian hereditary lands and Burgundian Low Countries, and Spain with its possessions of the southern Italian kingdoms of Sicily, Naples, and Sardinia. In the Americas, he oversaw the continuation of Spanish colonisation and a short-lived German colonisation. The personal union of the European and American territories he ruled was the first collection of realms labelled "the empire on which the sun never sets". Charles was born in Flanders to Habsburg Archduke Philip the Handsome, son of Maximilian I, Holy Roman Emperor and Mary of Burgundy, and Joanna of Castile, third child of Isabella I of Castile and Ferdinand II of Aragon, the Catholic Monarchs of Spain. Heir of his grandparents, Charles inherited his family's dominions at a young age. After his father's death in 1506, he inherited the Habsburg Netherlands in the Low Countries. In 1516, he became King of Spain as co-monarch of Castile and Aragon with his mother. Spain's possessions included the Castilian colonies of the Spanish West Indies and the Spanish Main, as well as Naples, Sicily and Sardinia. At the death of his paternal grandfather Maximilian in 1519, he inherited the Austrian hereditary lands and was elected as Holy Roman Emperor. He adopted the Imperial name of Charles V as his main title, and styled himself as a new Charlemagne. Charles revitalised the medieval concept of universal monarchy. With no fixed capital, he made 40 journeys through the different entities he ruled and spent a quarter of his reign travelling within his realms. Although his empire came to him peacefully, he spent most of his life waging war, exhausting his revenues and leaving debts in his attempt to defend the integrity of the Holy Roman Empire from the Protestant Reformation, the expansion of the Ottoman Empire, and in wars with France. Charles borrowed money from German and Italian bankers and, to repay them, relied on the wealth of the Low Countries and the flow of silver from New Spain and Peru, brought under his rule following the Spanish conquest of the Aztec and Inca empires, which caused widespread inflation. He supported the Magellan expedition, which resulted in the first circumnavigation of the world. Crowned King of Germany in Aachen, Charles sided with Pope Leo X and declared Martin Luther an outlaw at the Diet of Worms in 1521. The same year, Francis I of France, surrounded by the Habsburg possessions, started a war in Italy that led to his capture in the Battle of Pavia (1525). In 1527, Rome was sacked by an army of Charles's mutinous soldiers. Charles then defended Vienna from the Ottoman Turks and obtained coronations as King of Italy and Holy Roman Emperor from Pope Clement VII. In 1535, he took possession of Milan and captured Tunis. However, the loss of Buda during the struggle for Hungary and the Algiers expedition in the early 1540s frustrated his anti-Ottoman policies. After years of negotiations, Charles came to an agreement with Pope Paul III for the organisation of the Council of Trent (1545). The refusal of the Lutheran Schmalkaldic League to recognise the council's validity led to a war, won by Charles. However, Henry II of France offered new support to the Lutheran cause and strengthened the Franco-Ottoman alliance with Suleiman the Magnificent. Ultimately, Charles conceded the Peace of Augsburg and abandoned his multi-national project with abdications in 1556 that divided his hereditary and imperial domains between the Spanish Habsburgs, headed by his son Philip II of Spain, and the Austrian Habsburgs, headed by his brother Ferdinand. In 1557, Charles retired to the Monastery of Yuste in Extremadura and died there a year later.

The Sengoku period was the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. The Kyōtoku incident (1454), Ōnin War (1467), or Meiō incident (1493) are generally chosen as the period's start date, but there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what was traditionally considered the Edo period. Regardless of the dates chosen, the Sengoku period overlaps substantially with the Muromachi period (1336–1573).

Guadeloupe is an overseas department and region of France in the Caribbean. It consists of six inhabited islands—Basse-Terre, Grande-Terre, Marie-Galante, La Désirade, and two Îles des Saintes—and 30 uninhabited islets and 3 inhabited islets. It is south of Antigua and Barbuda and Montserrat and north of Dominica. The capital city is Basse-Terre, on the southern west coast of Basse-Terre Island; the most populous city is Les Abymes and the main centre of business is neighbouring Pointe-à-Pitre, both on Grande-Terre Island. It had a population of 395,726 in 2024.

The Battle of Berestechko (28 June – 10 July 1651) was fought between the Cossack Hetmanate and Crimean Khanate against the Polish–Lithuanian Commonwealth as a part of the Khmelnytsky Uprising. Near the site of the present-day city of Berestechko in Ukraine forces of the Zaporozhian Cossacks and Crimean Tatars under the command of Hetman Bohdan Khmelnytsky, Otaman Tymofiy Khmelnytsky, Colonels Ivan Bohun and Fylon Dzhalaliy with Khan İslâm III Giray and Tugay Bey, who was killed in the battle, were defeated by the Polish–Lithuanian Commonwealth's forces under the command of the Polish King John II Casimir, Prince Jeremi Wiśniowiecki, Hetmans Marcin Kalinowski and Stanisław Lanckoroński. It is considered to have been among the largest European land battles of the 17th century.

New England is a region consisting of six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York to the west and by the Canadian provinces of New Brunswick to the northeast and Quebec to the north. The Gulf of Maine and Atlantic Ocean are to the east and southeast, and Long Island Sound is to the southwest. Boston is New England's largest city and the capital of Massachusetts. Greater Boston, comprising the Boston–Worcester–Providence Combined Statistical Area, houses more than half of the region's total population. The Greater Boston area includes Worcester, Massachusetts, the second-largest city in New England; Manchester, New Hampshire, the largest city in New Hampshire; and Providence, Rhode Island, the capital of and largest city in Rhode Island. In 1620, the Pilgrims established Plymouth Colony, the second successful settlement in British America after the Jamestown Settlement in Virginia, founded in 1607. Ten years later, Puritans established Massachusetts Bay Colony north of Plymouth Colony. Over the next 126 years, people in the region fought in four French and Indian Wars until the English colonists and their Iroquois allies defeated the French and their Algonquian allies.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence or simply the American Revolution, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and, commanded by George Washington, defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 had led King George III and much of the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

The Continental Army was an army founded on June 14, 1775, by the Second Continental Congress in Philadelphia to coordinate the mutual defense of the United Colonies against the Kingdom of Great Britain during the Revolutionary War. It was periodically supplemented by state troops and volunteer militia. George Washington served as the Commander in Chief.

Corfu ( kor-FOO, -⁠FEW, US also KOR-foo, -⁠few) or Kerkyra (Greek: Κέρκυρα, romanized: Kérkyra, pronounced [ˈcercira] ) is one of the Ionian Islands in western Greece, and the northernmost island on Greece's west coast except for its satellite Diapontian Islands, which are also the westernmost point of all Greece. Corfu and the Diapontian Islands mark the International Hydrographic Organization border between the Ionian Sea to the south and the Adriatic Sea to the north. Within the Ionian Islands region, the regional unit of Corfu extends as far south as the Paxoi. The capital and largest city of the regional unit is also named Corfu. The island is bound up with the history of Greece from the beginnings of Greek mythology, and is marked by numerous battles and conquests. Ancient Korkyra took part in the Battle of Sybota, which was a catalyst for the Peloponnesian War, and, according to Thucydides, the largest naval battle between Greek city-states until that time. Thucydides also reports that Korkyra was one of the three great naval powers of Greece in the fifth century BCE, along with Athens and Corinth. Ruins of ancient Greek temples and other archaeological sites of the ancient city of Korkyra are located in Palaiopolis. Medieval castles, scattered across the island, are a legacy of struggles against invasions by pirates and the Ottomans. Two of these castles enclose its capital, which is the only city in Greece to be surrounded in such a way. As a result, Corfu's capital has been officially declared a kastropolis ('castle city') by the Greek government. From medieval times and into the 17th century, the island, as part of the Republic of Venice since 1204, successfully repulsed the Ottomans during several sieges, was recognised as a bulwark of the European States against the Ottoman Empire, and became one of the most fortified places in Europe. The fortifications of the island were used by the Venetians to defend against Ottoman intrusion into the Adriatic. In November 1815 Corfu came under British rule following the Napoleonic Wars, and in 1864 was ceded to modern Greece by the British government along with the remaining islands of the United States of the Ionian Islands under the Treaty of London. Corfu is the origin of the Ionian Academy, the first university of the modern Greek state, and the Nobile Teatro di San Giacomo di Corfù, the first Greek theatre and opera house of modern Greece. Ioannis Kapodistrias, the first governor of independent Greece after the revolution of 1821, founder of the modern Greek state, and a distinguished European diplomat, was born in Corfu. In 2007, the city's old town was added to the UNESCO World Heritage List, following a recommendation by ICOMOS. The 1994 European Union summit was held in Corfu. The island is a popular tourist destination.

The British invasions of the River Plate were two unsuccessful British attempts to seize control of the Spanish colony of the Viceroyalty of the Río de la Plata, located around the Río de la Plata in South America – in present-day Argentina and Uruguay. The invasions took place between 1806 and 1807, as part of the Napoleonic Wars, War of the Third Coalition at a time when Spain was an ally of Napoleonic France. In Argentine historiography, the two successive defeats of the British expeditionary forces are known collectively as the Reconquista and the Defensa, respectively.

The coronation of Victoria as queen of the United Kingdom took place on Thursday, 28 June 1838, just over a year after she succeeded to the throne of the United Kingdom at the age of 18. The ceremony was held in Westminster Abbey after a public procession through the streets from Buckingham Palace, to which the Queen returned later as part of a second procession. Planning for the coronation, led by the prime minister, Lord Melbourne, began at Cabinet level in March 1838. In the face of various objections from numerous parties, the Cabinet announced on Saturday, 7 April, that the coronation would be at the end of the parliamentary session in June. It was budgeted at £70,000 (equivalent to £6,700,000 in 2025), which was more than double the cost of the "cut-price" 1831 coronation, but considerably less than the £240,000 (equivalent to £22,800,000 in 2025) spent when George IV was crowned in July 1821. A key element of the plan was presentation of the event to a wider public. By 1838, the newly built railways were able to deliver huge numbers of people into London and it has been estimated that some 400,000 visitors arrived to swell the crowds who thronged the streets while the two processions took place and filled the parks where catering and entertainment were provided. Hyde Park was the scene of a huge fair, including a balloon ascent. The fair was scheduled to take place over two days, but was in the end extended by popular demand to four days. Green Park featured a firework display the night after the ceremony. The coronation coincided with a period of fine weather and the whole event was generally considered a great success by both the press and the wider public, although those inside the Abbey witnessed a good deal of mishap and confusion, largely due to lack of rehearsal time. In the country at large, there was opposition to the coronation by Radicals, especially in the North of England.

The Paris Opera Ballet (French: Ballet de l'Opéra national de Paris) is a French ballet company that is an integral part of the Paris Opera. It is the oldest national ballet company, and many European and international ballet companies can trace their origins to it. It is still regarded as one of the most prominent ballet companies in the world, together with the Bolshoi Ballet in Moscow and the Royal Ballet in London. Since December 2022, the company has been under the direction of José Martínez, the director of dance. The ballet company consists of 154 dancers, among them 17 Danseurs Étoiles. The principal dancers give 180 dance performances each year, primarily at the Palais Garnier. Just as prestigious as the Paris Opera Ballet is its dance school, the Paris Opera Ballet School (French: École de danse de l'Opéra national de Paris), considered to be one of the world's best dance schools. Its former pupils have won a record of 20 Benois de la Danse awards. The school celebrated its tercentennial in 2013. The competition for admission to both institutions is extremely fierce. For a dancer to enter the Paris Opera Ballet, it is almost compulsory to be admitted to the Paris Opera Ballet School, to pass the annual competitive examinations in May, and to attend at least the final two classes. 95 percent of the admitted dancers in the Paris Opera Ballet are French.

Sigma Chi (ΣΧ) is one of the largest North American social fraternities. The fraternity has 244 active undergraduate chapters and 152 alumni chapters in the United States and Canada and has initiated over 350,000 members. It was founded on June 28, 1855, at Miami University in Oxford, Ohio, by members who split from the Delta Kappa Epsilon fraternity. Sigma Chi is divided into seven operational entities: the Sigma Chi Fraternity, the Sigma Chi Foundation, the Sigma Chi Canadian Foundation, the Risk Management Foundation, Constantine Capital Inc., the Blue and Gold Travel Services, and the newly organized Sigma Chi Leadership Institute. According to the fraternity's constitution, "the purpose of this fraternity shall be to cultivate and maintain the high ideals of friendship, justice, and learning upon which Sigma Chi was founded."

A dog show is an animal show; it is an event where dogs are exhibited. A conformation show, also referred to as a breed show, is a kind of dog show in which a judge, familiar with a specific dog breed, evaluates individual purebred dogs for how well the dogs conform to the established breed type for their breed, as described in a breed's individual breed standard.

The Army of the Potomac was the primary field army of the Union army in the eastern theater of the American Civil War. It was created in July 1861 shortly after the First Battle of Bull Run and was disbanded in June 1865 following the surrender of the Confederate Army of Northern Virginia in April.

Bushrangers were armed robbers and outlaws who resided in the Australian bush between the 1780s and the early 20th century. The original use of the term dates back to the early years of the British colonisation of Australia, and applied to transported convicts who had escaped into the bush to hide from the authorities. By the 1820s, the term had evolved to refer to those who took up "robbery under arms" as a way of life, using the bush as their base.

The Austro-Serbian Convention of 1881 (German: Geheimvertrag zwischen Österreich-Ungarn und Serbien; Hungarian: Osztrák-magyar–szerb titkos egyezmény; Serbian: Аустро-српски савез из 1881) was a secret bilateral treaty that was signed in Belgrade on 28 June 1881 by Gabriel Freiherr Herbert-Rathkeal on behalf of Austria-Hungary and by Čedomilj Mijatović on behalf of the Principality of Serbia. The convention effectively turned Serbia into a protectorate state of Austria-Hungary, which meant its accession by proxy to the subsequent Triple Alliance (1882). Serbia then received Austrian support during the Serbo-Bulgarian War. The Balkans had been divided into spheres of influence, with Austria taking the western part (including Serbia) and Russia taking the eastern part (including Bulgaria). The treaty came after the railway convention of 6 April 1881 for the construction of the Belgrade–Niš section of the Vienna–Constantinople railway, and the trade treaty of 6 May 1881 which made Austria-Hungary virtually the sole market for agricultural products from Serbia and thereby dominant. After the Treaty of Berlin (1878), Serbia chose to accept Austria as its patron since Russia had become a protector of Bulgaria. Nevertheless, the conclusion of the convention was met with resentment and opposition from Russophile sections of the political class in Serbia, including opposition on the part of the Prime Minister Milan Piroćanac. Under the treaty, Austria-Hungary pledged to support the Obrenović dynasty, recognised the Serbian prince as king and acknowledged Serbia's southward territorial claims. In return, Serbia undertook not to allow any agitation or military activity inimical to Austro-Hungarian interests, which notably included those in Bosnia and Herzegovina and Sanjak of Novi Pazar, and all foreign treaties of Serbia were to obtain Vienna's prior approval.

Labour Day is an official public holiday in many countries. In most countries, Labour Day is synonymous with, or linked with, International Workers' Day, which happens on 1 May. It was originally chosen to commemorate the 1886 general strike which culminated in the Haymarket affair. In the United States and Canada, it is a public holiday on the first Monday in September.

The United States Congress is the legislative branch of the federal government of the United States. It is a bicameral legislature, including a lower body, the U.S. House of Representatives, and an upper body, the U.S. Senate. They both meet in the United States Capitol in Washington, D.C.

SS Norge was a transatlantic ocean liner that was launched in 1881 in Scotland, and was lost in 1904 off Rockall with great loss of life. Her final voyage was from Copenhagen, Kristiania and Kristiansand, bound for New York, carrying passengers many of whom were emigrants. It was the biggest civilian maritime disaster in the Atlantic Ocean until the sinking of Titanic eight years later, and is still the largest loss of life from a Danish merchant ship.

Nakhla is a Martian meteorite which fell in Egypt in 1911. It was the first meteorite reported from Egypt, the first one to suggest signs of aqueous processes on Mars, and the prototype for Nakhlite type of meteorites.

Identifying the causes of World War I remains a debated issue. World War I began in the Balkans on 28 July 1914, and hostilities ended on 11 November 1918, leaving 17 million dead and 25 million wounded. Moreover, the Russian Civil War can in many ways be considered a continuation of World War I, as can various other conflicts in the direct aftermath of 1918. Scholars looking at the long term seek to explain why two rival sets of powers (the German Empire, Austria-Hungary, and the Ottoman Empire against the Russian Empire, France, and the British Empire) came into conflict by the start of 1914. They look at such factors as political, territorial and economic competition; militarism, a complex web of alliances and alignments; imperialism, the growth of nationalism; and the power vacuum created by the decline of the Ottoman Empire. Other important long-term or structural factors that are often studied include unresolved territorial disputes, the perceived breakdown of the European balance of power, convoluted and fragmented governance, arms races and security dilemmas, a cult of the offensive, and military planning. Scholars seeking short-term analysis focus on the summer of 1914 and ask whether the conflict could have been stopped, or instead whether deeper causes made it inevitable. Among the immediate causes were the decisions made by statesmen and generals during the July Crisis, which was triggered by the assassination of Archduke Franz Ferdinand of Austria by the Bosnian Serb nationalist Gavrilo Princip, who had been supported by a nationalist organization in Serbia. The crisis escalated as the conflict between Austria-Hungary and Serbia was joined by their allies Russia, Germany, France, and ultimately Belgium and the United Kingdom. Other factors that came into play during the diplomatic crisis leading up to the war included misperceptions of intent (such as the German belief that the UK would remain neutral), the fatalistic belief that war was inevitable, and the speed with which the crisis escalated, partly due to delays and misunderstandings in diplomatic communications. The crisis followed a series of diplomatic clashes among the Great Powers (Italy, France, Germany, Britain, Austria-Hungary and Russia) over European and colonial issues in the decades before 1914 that had left tensions high. The cause of these public clashes can be traced to changes in the balance of power in Europe that had been taking place since 1867. Consensus on the origins of the war remains elusive, since historians disagree on key factors and place differing emphasis on a variety of factors. That is compounded by historical arguments changing over time, particularly as classified historical archives become available, and as perspectives and ideologies of historians have changed. The deepest division among historians is between those who see Germany and Austria-Hungary as having driven events and those who focus on power dynamics among a wider set of actors and circumstances. Secondary fault lines exist between those who believe that Germany deliberately planned a European war, those who believe that the war was largely unplanned but was still caused principally by Germany and Austria-Hungary taking risks, and those who believe that some or all of the other powers (Russia, France, Serbia, the UK) played a more significant role in causing the war than has been traditionally suggested.

At the outbreak of World War I in August 1914, the Kingdom of Greece remained neutral. Nonetheless, in October 1914, Greek forces once more occupied Northern Epirus, from where they had retreated after the end of the Balkan Wars. The disagreement between King Constantine, who favoured neutrality, and the pro-Allied Prime Minister Eleftherios Venizelos led to the National Schism, the division of the state between two rival governments. Finally, Greece united and joined the Allies in the summer of 1917.

The Treaty of Versailles was a peace treaty signed on 28 June 1919. As the most important treaty of World War I, it ended the state of war between Germany and most of the Allied Powers. It was signed in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, the proximate cause of the war. The other Central Powers on the German side signed separate treaties. Although the armistice of 11 November 1918 ended the actual fighting, and agreed certain principles and conditions including the payment of reparations, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. Germany was not allowed to participate in the negotiations before signing the treaty.

Alexander I Karađorđević was King of the Serbs, Croats and Slovenes from 16 August 1921 to 3 October 1929 and King of Yugoslavia from 3 October 1929 until his assassination. His thirteen-year reign was the longest of the kingdom's three monarchs. He served as the de facto head of state of the Kingdom of Serbia from 1914 to 1918 and of Yugoslavia from 1918 to 1921 as prince regent for his father, Peter I.

The Irish Civil War was a conflict that followed the Irish War of Independence and accompanied the establishment of the Irish Free State, an entity independent from the United Kingdom but within the British Empire.

Mengjiang, also known as Mengkiang, officially the Mengjiang United Autonomous Government, was an autonomous zone of the Wang Jingwei regime in Inner Mongolia. It was formed in 1939 as its own puppet state of the Empire of Japan, and from 1940 was placed under the sovereignty of the Wang Jingwei regime, which was itself a puppet government. It consisted of the previously Chinese provinces of Chahar and Suiyuan, corresponding to the central part of modern Inner Mongolia. It has also been called Mongukuo or Mengguguo. The capital was Kalgan, from where it was under the nominal rule of Mongol nobleman Demchugdongrub. The territory returned to Chinese control after the defeat of the Japanese Empire in 1945.

The Kingdom of Romania was a constitutional monarchy that existed from 25 March [O.S. 13 March] 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I, until 30 December 1947 with the abdication of King Michael I and the Romanian Parliament proclamation of the Romanian People's Republic.

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 Provisional Government of National Unity was a provisional government formed by the decree of the State National Council on 28 June 1945 as a result of reshuffling the Soviet-backed Provisional Government of the Republic of Poland established by the Polish Workers' Party through inclusion of politicians from the close political sphere of Stanisław Mikołajczyk, the former prime minister of the Polish government-in-exile based in London. Inclusion of the latter group provided an excuse for the Western allies to approve the fait accompli of Poland tacitly becoming part of the Soviet sphere of influence, and to legitimise the Warsaw government while withdrawing their recognition of the Polish government-in-exile. The puppet government became known as the "Lublin Committee" or the "Lublin Poles" or the "Lublin Government", and it garnered the recognition of all Allied governments at the time.

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 Korean War was an armed conflict fought on the Korean Peninsula between North Korea and South Korea and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations led by the United States under the auspices of the United Nations Command (UNC).

The Hangang Bridge bombing was a demolition operation conducted by the South Korean Army to destroy the Hangang Bridge in Seoul, South Korea, on 28 June 1950, to delay the rapid North Korean Army advance towards the Southern part of Seoul.

The Korean People's Army encompasses the combined military forces of North Korea and the armed wing of the Workers' Party of Korea (WPK).
