September 1 in History

Isaac I Komnenos or Comnenus (Ancient Greek: Ἰσαάκιος Κομνηνός, romanized: Isaákios Komnēnós; c. 1007 – 1 June 1060) was Byzantine emperor from 1057 to 1059, the first reigning member of the Komnenian dynasty. The son of the general Manuel Erotikos Komnenos, he was orphaned at an early age, and was raised under the care of Emperor Basil II. He made his name as a successful military commander, serving as commander-in-chief of the eastern armies between c. 1042 and 1054. In 1057 he became the head of a conspiracy of the dissatisfied eastern generals against the newly crowned Michael VI Bringas. Proclaimed emperor by his followers on 8 June 1057, he rallied sufficient military forces to defeat the loyalist army at the Battle of Hades. While Isaac was willing to accept a compromise solution by being appointed Michael's heir, a powerful faction in Constantinople, led by the ambitious Patriarch of Constantinople, Michael Keroularios, pressured Michael to abdicate. After Michael abdicated on 30 August 1057, Isaac was crowned emperor in the Hagia Sophia on 1 September. As emperor, he rewarded his supporters, but also embarked on a series of fiscal measures designed to shore up revenue and eliminate the excesses allowed to flourish under his predecessors. His aim was to fill the treasury and restore the Byzantine army's effectiveness to preserve the empire. The reduction of salaries, harsh tax measures and confiscation of Church properties aroused much opposition, particularly from Patriarch Keroularios, who had come to think of himself as a king-maker. In November 1058, Keroularios was arrested and exiled, and died before a synod to depose him could be convened. The eastern frontier held firm during Isaac's reign, Hungarian raids were resolved by a treaty in 1059, while the restive Pechenegs were subdued by Isaac in person in summer 1059. Shortly after, Isaac fell ill, and on the advice and pressure of Michael Psellos, he abdicated his throne in favour of Constantine X Doukas, retiring to the Stoudion monastery where he died later in 1060.

Lund Cathedral (Swedish: Lunds domkyrka) is a cathedral of the Lutheran Church of Sweden in Lund, Scania, Sweden. It is the seat of the Bishop of Lund and the main church of the Diocese of Lund. It was built as the Catholic cathedral of the archiepiscopal see of all the Nordic countries, dedicated to Saint Lawrence. It is one of the oldest stone buildings still in use in Sweden. Lund Cathedral has been called "the most powerful representative of Romanesque architecture in the Nordic countries." At the time of its construction, Lund and the cathedral belonged to Denmark. The main altar was consecrated in 1145 and the cathedral was by that time largely finished; the western towers were built somewhat later. Its architecture shows clear influences from contemporary north Italian architecture, conveyed via the Rhine Valley. The earliest architect was named Donatus, though his precise role in the construction of the cathedral is difficult to determine. The new cathedral was richly decorated with stone sculpture, including two unusual statues in the crypt traditionally called "The giant Finn and his wife" about which a local legend has developed. The cathedral was severely damaged in a fire in 1234, and major restoration works were carried out in the early 16th century under the leadership of Adam van Düren. Following the Reformation, the cathedral suffered from lost income and dilapidation. In 1658, the city of Lund and the cathedral became a part of Sweden following the Treaty of Roskilde. Lund Cathedral was the site of the ceremony acknowledging the founding of Lund University in 1668. Repairs were made during the 18th century but in 1832 a complete restoration of the cathedral was recommended. Subsequently, much of the cathedral was restored and rebuilt during most of the 19th century. The work was first led by Carl Georg Brunius and later by architect Helgo Zettervall and not entirely finished until 1893. The changes implemented during the 19th century were extensive; among other things, Zettervall had the entire western part, including the towers, demolished and rebuilt to his own designs. The medieval cathedral contains several historic furnishings and works of art. Its main altarpiece was donated to the cathedral in 1398, and it also contains Gothic choir stalls, bronzes and an astronomical clock from the 15th century (although heavily restored in 1923). When it was built, Lund Cathedral was lavishly decorated with Romanesque stone sculptures. It also contains late medieval stone sculptures from the time of Adam van Düren's renovation. After the Reformation the cathedral was also equipped with a decorated pulpit. Of more recent date is the large mosaic in the apse, by Joakim Skovgaard, installed in 1927. Lund Cathedral has six church organs, one of which is the largest in Sweden, and is also used as a concert venue.

Stamira (sometimes spelled Stamura) (date of birth unknown – Ancona, 1 September 1173) was, according to a long-standing tradition, a heroic self-sacrificing woman who saved the city of Ancona during the 1173 siege by Holy Roman Emperor Frederick Barbarossa. Her memory was later taken up prominently by Italian nationalism.

Pope Lucius III (born Ubaldo Allucingoli; 1100 – 25 November 1185) was head of the Catholic Church and sovereign of the Papal States from 1181 until his death in 1185. Born in the Holy Roman Empire to an aristocratic family, he emerged as an experienced papal diplomat. His papacy was marked by conflict with the Holy Roman Emperor Frederick I (Frederick Barbarossa), culminating in his exile from Rome, and initial preparations for the Third Crusade. Born in Lucca, Ubaldo Allucingoli rose to prominence within the Catholic Church, eventually becoming Pope Lucius III. He was appointed cardinal by Pope Innocent II and served as papal legate in France, Sicily, and other regions. He was involved in negotiating the Treaty of Venice in 1177, and was elected pope in 1181. During his papacy, Lucius III faced disputes with the Holy Roman Emperor Frederick I over the territories of the late Countess Matilda of Tuscany. He also held a synod in 1184 that condemned various heretical groups. In 1185, preparations began for the Third Crusade, but Lucius III died in Verona before they were completed.

The papal election that followed the death of Pope Clement IV lasted from 1 December 1268 to 1 September 1271 and was the longest in the history of the Catholic Church. This was due primarily to political infighting between the cardinals. The election of Teobaldo Visconti as Pope Gregory X was the first example of a papal election by "compromise", that is, by the appointment of a committee of six cardinals agreed to by the other ten. (This method was attempted once before, in the 1227 papal election, but the choice of the committee refused the honor and the full group of cardinals proceeded to elect the pope.) The election occurred more than a year after the magistrates of Viterbo locked the cardinals in, reduced their rations to bread and water, and removed the roof of the Palace of the Popes in Viterbo where the election took place. As a result of the length of the election, during which three of the twenty cardinal-electors died and one resigned, Gregory X promulgated the papal bull Ubi periculum on 7 July 1274, during the Second Council of Lyon, establishing the papal conclave, whose rules were based on the tactics employed against the cardinals in Viterbo. The first election held under those rules is sometimes viewed as the first conclave.

Stephen Tvrtko I (Serbo-Croatian: Stjepan/Stefan Tvrtko / Стјепан/Стефан Твртко; c. 1338 – 10 March 1391) was the first king of Bosnia. A member of the House of Kotromanić, he succeeded his uncle Stephen II as the ban of Bosnia in 1353. As he was a minor at the time, Tvrtko's father, Vladislav, briefly ruled as regent, followed by Tvrtko's mother, Jelena. Early in his personal rule, Tvrtko quarrelled with his country's Roman Catholic clergy but later enjoyed cordial relations with all the religious communities in his realm. After initial difficulties—the loss of large parts of Bosnia to his overlord, King Louis I of Hungary, and being briefly deposed by his magnates—Tvrtko's power grew considerably. He conquered some remnants of the neighbouring Serbian Empire in 1373, after the death of its last ruler and his distant relative, Uroš the Weak. In 1377, he had himself crowned king of Bosnia and Serbia, claiming to be the heir of Serbia's extinct Nemanjić dynasty. As the Kingdom of Bosnia continued to expand, Tvrtko's attention shifted to the Adriatic coast. He gained control of the entire Primorje region and the major maritime cities of the area, established new settlements and started building a navy, but never succeeded in subjugating the lords of the independent Serbian territories. The death of King Louis and the accession of Queen Mary in 1382 allowed Tvrtko to take advantage of the ensuing succession crisis in Hungary and Croatia. After bitter fighting, from 1385 to 1390, Tvrtko succeeded in conquering large parts of Dalmatia, and Croatia proper. Following the Battle of Kosovo in 1389, his tenuous claim to Serbia became a mere fiction, as the Serbian rulers he sought to subdue became vassals of the victorious Ottoman Empire. The Ottoman Turks also launched their first attacks on Bosnia during Tvrtko's reign, but his army was able to repel them. Tvrtko's sudden death in 1391 prevented him from solidifying the Kotromanić hold on Croatian lands. Tvrtko is widely considered one of Bosnia's greatest medieval rulers, having enlarged the country's borders to their greatest extent, left a strong economy, and improved the living standards of his subjects. He was survived by at least one son, Tvrtko II, but was succeeded by Dabiša, under whom Tvrtko's burgeoning realm began to decay.

The Tumu Crisis, also known as the Crisis of the Tumu Fortress, or the Jisi Incident, was a border conflict between the Oirat Mongols and the Ming dynasty of China. In July 1449, Esen Taishi, leader of the Oirat Mongols, launched a large-scale, three-pronged invasion of China. Despite having capable generals, Emperor Yingzong of Ming, under the influence of eunuch Wang Zhen who dominated the Ming court at the time, made the decision to personally lead his armies into battle against Esen. On 1 September, the Ming army suffered a crushing defeat at the hands of the much weaker Mongols, and the Emperor was captured. This defeat was one of the biggest military failures in the Ming dynasty's three centuries of existence, and it was largely attributed to the poor leadership of their army. Esen was not prepared for the scale of his victory or for the capture of the Ming emperor. Initially, he attempted to use the captured Emperor to raise a ransom and planned to conquer the undefended Ming capital of Beijing. His plan was foiled due to the steadfast leadership of the commander in the capital, Yu Qian, and the ascension of the captured Emperor's brother, the Jingtai Emperor. Emperor Yingzong was eventually released in 1450, but his brother placed him under house arrest. Esen faced growing criticism for his failure to exploit his victory over the Ming and was assassinated six years after the battle in 1455.

Anne Boleyn (; c. 1501 or 1507 – 19 May 1536) was Queen of England from 1533 to 1536, as the second wife of King Henry VIII. The circumstances of her marriage and execution, by beheading for treason, made her a key figure in the political and religious upheaval that marked the start of the English Reformation. Anne was the daughter of Thomas Boleyn (later Earl of Wiltshire), and his wife, Elizabeth Howard, and was educated in the Netherlands and France. Anne returned to England in early 1522, to marry her cousin James Butler, 9th Earl of Ormond; the marriage plans were broken off, and instead, she secured a post at court as maid of honour to Henry VIII's wife, Catherine of Aragon. Early in 1523, Anne was secretly betrothed to Henry Percy, son of Henry Percy, 5th Earl of Northumberland, but the betrothal was broken off when the Earl refused to support it. Cardinal Thomas Wolsey refused the match in January 1524. In February or March 1526, Henry VIII began his pursuit of Anne. She resisted his attempts to seduce her, refusing to become his mistress, as her sister Mary had previously been. Henry focused on annulling his marriage to Catherine, so he would be free to marry Anne. After Wolsey failed to obtain an annulment from Pope Clement VII, it became clear the marriage would not be annulled by the Catholic Church. As a result, Henry and his advisers, such as Thomas Cromwell, began breaking the Church's power in England and closing the monasteries. Henry and Anne formally married on 25 January 1533, after a secret wedding on 14 November 1532. On 23 May 1533, the newly appointed Archbishop of Canterbury Thomas Cranmer declared Henry and Catherine's marriage null and void. Five days later, he declared Henry and Anne's marriage valid. Pope Clement excommunicated Henry and Cranmer. As a result of the marriage and excommunications, the first break between the Church of England and the Catholic Church took place, and the King took control of the Church of England. Anne was crowned queen on 1 June 1533. On 7 September, she gave birth to the future Queen Elizabeth I. Henry was disappointed to have a daughter, but hoped a son would follow and professed to love Elizabeth. Anne subsequently had three miscarriages and by March 1536, Henry was courting Jane Seymour. Henry had Anne investigated for high treason in April 1536. On 2 May 1536, she was arrested and sent to the Tower of London, where she was put on trial before a jury, including Henry Percy, her former betrothed, and her uncle Thomas Howard, 3rd Duke of Norfolk. She was convicted on 15 May 1536 and beheaded four days later. Most historians dispute the charges, which included adultery, incest with her brother George, and plotting to kill the King. After her daughter, Elizabeth, became queen in 1558, Anne became venerated as a martyr and heroine of the English Reformation, particularly through the works of George Wyatt. She has inspired, or been mentioned in, many cultural works and retained her hold on the popular imagination. She has been called "the most influential and important queen consort England has ever had", as she provided the occasion for Henry to declare the English Church's independence from the Vatican.

The Guru Granth Sahib is the central holy religious scripture of Sikhism, regarded by Sikhs as the final, sovereign and eternal Guru following the lineage of the ten human gurus of the religion.

Claudio Giovanni Antonio Monteverdi (baptized 15 May 1567 – 29 November 1643) was an Italian composer, choirmaster and string player. A composer of both secular and sacred music, and a pioneer in the development of opera, he is considered a crucial transitional figure between the Renaissance and Baroque periods of music history. Born in Cremona, where he undertook his first musical studies and compositions, Monteverdi developed his career first at the court of Mantua (c. 1590–1613) and then until his death in the Republic of Venice where he was maestro di cappella at the basilica of San Marco. His surviving letters give insight into the life of a professional musician in Italy of the period, including problems of income, patronage and politics. Much of Monteverdi's output, including many stage works, has been lost. His surviving music includes nine books of madrigals, large-scale religious works, such as his Vespro della Beata Vergine (Vespers for the Blessed Virgin) of 1610, and three complete operas. His opera L'Orfeo (1607) is the earliest of the genre still widely performed; towards the end of his life he wrote works for Venice, including Il ritorno d'Ulisse in patria and L'incoronazione di Poppea. While he worked extensively in the tradition of earlier Renaissance polyphony, as evidenced in his madrigals, he undertook great developments in form and melody, and began to employ the basso continuo technique, distinctive of the Baroque. No stranger to controversy, he defended his sometimes novel techniques as elements of a seconda pratica, contrasting with the more orthodox earlier style which he termed the prima pratica. Largely forgotten during the eighteenth and much of the nineteenth centuries, his works enjoyed a rediscovery around the beginning of the twentieth century. He is now established both as a significant influence in European musical history and as a composer whose works are regularly performed and recorded.

The English Civil War or Great Rebellion was a series of civil wars and political machinations between Royalists and Parliamentarians in the Kingdom of England from 1642 to 1651. Part of the wider 1639 to 1653 Wars of the Three Kingdoms, the struggle consisted of the First English Civil War and the Second English Civil War. The Anglo-Scottish war of 1650 to 1652 is sometimes referred to as the Third English Civil War.

Louis XV (15 February 1710 – 10 May 1774), known as Louis the Beloved (French: le Bien-Aimé), was King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity (then defined as his 13th birthday) in 1723, the kingdom was ruled by his grand-uncle Philippe II, Duke of Orléans, as Regent of France. Cardinal Fleury was chief minister from 1726 until his death in 1743, at which time the king took sole control of the kingdom. His reign of almost 59 years (from 1715 to 1774) was the second longest in the history of France, exceeded only by his predecessor, Louis XIV, who had ruled for 72 years (from 1643 to 1715). In 1748, Louis returned the Austrian Netherlands, won at the Battle of Fontenoy of 1745. He ceded New France in North America to Great Britain and Spain at the conclusion of the disastrous Seven Years' War in 1763. He incorporated the territories of the Duchy of Lorraine and the Corsican Republic into the Kingdom of France. Historians generally criticize his reign and maintain that his incompetence and extravagance weakened France, depleted the treasury, discredited the absolute monarchy, and diminished the country's reputation internationally. However, a minority of scholars argue that he was popular during his lifetime, but that his reputation was later blackened by revolutionary propaganda. His grandson and successor Louis XVI inherited a kingdom on the brink of financial disaster and gravely in need of political reform, laying the groundwork for the French Revolution of 1789.

Catherine II (born Sophie Auguste Friederike von Anhalt-Zerbst; 2 May 1729 – 17 November 1796), known as Catherine the Great, was Empress of Russia from 9 July 1762 until her death in 1796. Before her accession, Catherine had been a royal consort as the wife of Emperor Peter III, whom she overthrew in a coup d'état. Her reign of over 34 years saw an era of prosperity during the Enlightenment in which many new cities, universities and theatres were established; large-scale immigration from the rest of Europe occurred; and the Russian Empire was recognised as a great power of Europe. Born a German princess, Catherine married Peter, a grandson of Peter the Great, at the age of 16. Peter became Emperor of Russia in 1762, reigning for seven months before his deposition and possible assassination at the hands of Catherine. During her reign, she often maintained close alliances with noble favourites such as Count Grigory Orlov and Grigory Potemkin. She appointed and worked with several highly successful generals such as Alexander Suvorov and Pyotr Rumyantsev and admirals such as Samuel Greig and Fyodor Ushakov. She governed at a time when the Russian Empire was expanding rapidly by conquest and diplomacy. In the west, she installed her former lover to the throne of Poland, which was eventually partitioned. In the south, the Crimean Khanate was annexed following victories over the Bar Confederation and the Ottoman Empire in the Russo-Turkish War. With the support of Great Britain, Russia colonised the territories of New Russia along the coasts of the Black and Azov seas. In the east, Russians became the first Europeans to colonise Alaska, establishing Russian America. Many cities and towns were founded on Catherine's orders in the newly conquered lands, most notably Yekaterinoslav, Kherson, Nikolayev, and Sevastopol. An admirer of Peter the Great, Catherine continued to modernise Russia along Western European culture. However, military conscription and the economy continued to depend on serfdom, and the increasing demands of the state and of private landowners intensified the exploitation of serf labour. This was one of the chief reasons behind rebellions, including Pugachev's Rebellion of Cossacks, nomads, peoples of the Volga, and peasants. The Manifesto on Freedom of the Nobility, issued during the short reign of Peter III and confirmed by Catherine, freed Russian nobles from compulsory military or state service. The construction of many mansions of the nobility in the classical style endorsed by the empress changed the face of the country. She is often included in the ranks of the enlightened despots. Catherine presided over the age of the Russian Enlightenment and established the Smolny Institute of Noble Maidens, the first state-financed higher education institution for women in Europe.

Mission San Luis Obispo de Tolosa (Spanish: Misión San Luis Obispo de Tolosa) is a Spanish mission founded September 1, 1772 by Father Junípero Serra in San Luis Obispo, California. The mission was named after San Luis, obispo de Tolosa (Saint Louis, bishop of Toulouse, France). The Mission of San Luis Obispo is unusual in its design, in that its combination of belfry and vestibule are found nowhere else among the California missions. Like other churches, the main nave is short and narrow, but at the San Luis Obispo Mission, there is a secondary nave of almost equal size situated to the right of the altar, making it the only L-shaped mission church in California.

The Province of Massachusetts Bay was a colony in New England which became one of the thirteen original states of the United States. It was chartered on October 7, 1691, by William III and Mary II, the joint monarchs of the kingdoms of England, Scotland, and Ireland, and was based on the merging of several earlier British colonies in New England. The charter took effect on May 14, 1692, and included the Massachusetts Bay Colony, the Plymouth Colony, the Province of Maine, the Territory of Sagadahock, Martha's Vineyard, Nantucket, Nova Scotia, and New Brunswick; the Commonwealth of Massachusetts is the direct successor. Maine has been a separate state since 1820, and Nova Scotia and New Brunswick are now Canadian provinces, having been part of the colony only until 1697.

Juno (minor-planet designation: 3 Juno) is a large asteroid in the asteroid belt. Juno was the third asteroid discovered, in 1804, by German astronomer Karl Harding. It is tied with three other asteroids as the thirteenth largest asteroid, and it is one of the two largest stony (S-type) asteroids, along with 15 Eunomia. It is estimated to contain 1% of the total mass of the asteroid belt.

The Pontifical Equestrian Order of St. Gregory the Great (Latin: Ordo Sancti Gregorii Magni; Italian: Ordine di San Gregorio Magno) was established on 1 September 1831, by Pope Gregory XVI, seven months after his election as Pope. The order is one of the five orders of knighthood of the Holy See. The honor is bestowed upon Catholic men and women (and certain notable non-Catholics) in recognition of their personal service to the Holy See and to the Catholic Church, through their unusual labors, their support of the Holy See, and the examples they set in their communities and their countries. The Order of Saint Gregory the Great is the most recognizable of the papal awards and the most frequently granted to lay persons based on their merits. Based on the Acta Apostolica Sedis, 4177 persons have received (globally) a pontifical knighthood between 2000 and 2020 (the UK had 181 recipients and France 170). From the awardees of papal knighthood, the recipients of the Order of Saint Gregory are the most numerous.

Narcissa Prentiss Whitman (March 14, 1808 – November 29, 1847) was an American missionary in the Oregon Country of what would become the state of Washington. On their way to found the Protestant Whitman Mission in 1836 with her husband, Marcus, near modern-day Walla Walla, Washington, she and Eliza Hart Spalding (wife of Henry Spalding) became the first documented European-American women to cross the Rocky Mountains.

The Saint Andrew's Scots School (Spanish: Escuela Escocesa San Andrés), also referred to as Saint Andrew's, is an Argentine bilingual school in Olivos, Vicente López Partido, Buenos Aires Province. Established in 1838 in downtown Buenos Aires, the school offers early childhood, primary and secondary education and has a university founded in 1988. The school's campus is located in San Fernando, Tigre Partido, inside the urban area known as Greater Buenos Aires.

The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. The geomagnetic storm was most likely the result of a coronal mass ejection (CME) from the Sun colliding with Earth's magnetosphere. The geomagnetic storm was associated with a very bright solar flare on 1 September 1859. It was observed and recorded independently by British astronomers Richard Carrington and Richard Hodgson—the first records of a solar flare. A geomagnetic storm of this magnitude occurring today has the potential to cause widespread electrical disruptions and blackouts as well as damage to the electrical power grid and satellites.

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.

The Battle of Jonesborough (August 31 – September 1, 1864) was fought between Union Army forces led by William Tecumseh Sherman and Confederate forces under William J. Hardee during the Atlanta campaign in the American Civil War. On the first day, on orders from Army of Tennessee commander John Bell Hood, Hardee's troops attacked the Federals and were repulsed with heavy losses. That evening, Hood ordered Hardee to send half his troops back to Atlanta. On the second day, five Union corps converged on Jonesborough (modern name: Jonesboro). For the only time during the Atlanta Campaign, a major Federal frontal assault succeeded in breaching the Confederate defenses. The attack took 900 prisoners, but the defenders were able to halt the breakthrough and improvise new defenses. Despite facing overwhelming odds, Hardee's corps escaped undetected to the south that evening. Thwarted in his earlier attempts to force Hood to abandon Atlanta, Sherman resolved to make a sweep to the south with six of his seven infantry corps. His objective was to block the Macon and Western Railroad which was the last uncut railroad leading into Atlanta. Three corps from Sherman's army got within artillery range of the railroad at Jonesborough and Hood reacted by sending two of his three infantry corps to drive them away. While the fighting at Jonesborough was going on, two more Union corps blocked the railroad on August 31. When Hood found that Atlanta's railroad lifeline was severed, he evacuated the city on the evening of September 1. Atlanta was occupied by Union troops the next day and the Atlanta campaign was concluded. Although Hood's army was not destroyed, the fall of Atlanta had far-reaching political as well as military effects on the course of the war.

The Franco-Prussian War, occasionally known as the Franco-German War, and sometimes referred to in France as the War of 1870, was a conflict between France and the North German Confederation led by Prussia. Lasting from 19 July 1870 to 28 January 1871, the conflict was caused primarily by France's determination to reassert its dominant position in continental Europe, which appeared in question following the decisive Prussian victory over Austria in 1866. After Prince Leopold of Hohenzollern of the Roman Catholic branch Hohenzollern-Sigmaringen had been offered the vacant Spanish throne in 1870 and had withdrawn his acceptance, the French ambassador approached Prussian King Wilhelm I at his vacationing site in Ems demanding Prussia renounce any future claims, which Wilhelm rejected. The internal Ems dispatch reported this to Berlin on July 13; Prussian chancellor Otto von Bismarck quickly then made it public with altered wording. Thus the French newspapers for July 14, the French national holiday contained translations of Bismarck's press release, but not a report from their own ambassador. A crowd in the streets of Paris demanded war, and soon French mobilization was ordered. According to some historians, Bismarck deliberately provoked the French into declaring war on Prussia in order to induce four independent southern German states—Baden, Württemberg, Bavaria and Hesse-Darmstadt—to join the North German Confederation. Other historians contend that Bismarck exploited the circumstances as they unfolded. All agree that Bismarck recognized the potential for new German alliances, given the situation as a whole. France mobilised its army on 15 July 1870, leading the North German Confederation to respond with its own mobilisation later that day. On 16 July 1870, the French parliament voted to declare war on Prussia; France invaded German territory on 2 August. The German coalition mobilised its troops much more effectively than the French and invaded northeastern France on 4 August. German forces were superior in numbers, training, and leadership and made more effective use of modern technology, particularly railways and artillery. A series of hard-fought Prussian and German victories in eastern France, culminating in the Siege of Metz and the Battle of Sedan, resulted in the capture of the French Emperor Napoleon III and the decisive defeat of the army of the Second Empire; a Government of National Defense was formed in Paris on 4 September and continued the war for another five months. German forces fought and defeated new French armies in northern France, then besieged Paris for over four months before it fell on 28 January 1871, effectively ending the war. In the final days of the war, with German victory all but assured, the German states proclaimed their union as the German Empire under the Prussian king Wilhelm I. With the notable exceptions of Austria and German Switzerland, the vast majority of German-speakers were united under a nation-state for the first time. Following an armistice with France, the Treaty of Frankfurt was signed on 10 May 1871, giving Germany billions of francs in war indemnity, as well as most of Alsace and parts of Lorraine, which became the Imperial Territory of Alsace-Lorraine (Reichsland Elsaß-Lothringen). The war had a lasting impact on Europe. By hastening German unification, the war significantly altered the balance of power on the continent, with the new German state supplanting France as the dominant European land power. Bismarck maintained great authority in international affairs for two decades, developing a reputation for Realpolitik that raised Germany's global stature and influence. In France, it brought a final end to imperial rule and began the first lasting republican government. Resentment over the French government's handling of the war and its aftermath triggered the Paris Commune, a revolutionary uprising which seized and held power for two months before its suppression; the event would influence the politics and policies of the Third Republic.

Ghazi Mohammad Ayub Khan Barakzai, (1857 – 7 April 1914) nicknamed the Victor of Maiwand, and as the Afghan Prince Charlie was, for a while, the governor of Herat Province in the Emirate of Afghanistan. He was briefly the Emir of Afghanistan, from 12 October 1879 to 31 May 1880. He also led the Afghan troops during the Second Anglo-Afghan War and defeated the British Indian Army at the Battle of Maiwand. Following his defeat at the Battle of Kandahar, Ayub Khan was deposed and exiled to British India. However, Ayub Khan fled to Persia (now Iran). After negotiations in 1888 with Sir Mortimer Durand, the United Kingdom's ambassador at Tehran, Ayub Khan became a pensioner of the British Raj and traveled to British India in 1888, where he lived in Lahore, Punjab, until his death in 1914. He was buried in Peshawar and had eleven wives, fifteen sons, and ten daughters. Two of his grandsons, Sardar Hissam Mahmud el-Effendi and Sardar Muhammad Ismail Khan, served as brigadiers in the Pakistan Army.

Its primary objective was to get streetcar lines off the traffic-clogged streets instead of as a true rapid transit line, and its construction was partially influenced by the blizzard of 1888 which resulted in transportation gridlock. It now forms the central part of the Green Line, connecting Boylston Street to Park Street and Government Center stations.

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.
