October 8 in History

Constantine I, also known as Constantine the Great, was Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity. He played a pivotal role in elevating the status of Christianity in the Roman Empire, the Edict of Milan decriminalising Christian practice and ceasing Christian persecution. This was a turning point in the Christianisation of the Roman Empire. He founded the city of Constantinople and made it the capital of the Empire, which it remained for over a millennium.

The Council of Chalcedon (; Latin: Concilium Chalcedonense) was the fourth ecumenical council of the Christian Church. It was convoked by the Roman emperor Marcian. The council convened in the city of Chalcedon, Bithynia (modern-day Kadıköy, Istanbul, Turkey) from 8 October to 1 November 451. The council was attended by over 520 bishops or their representatives, making it the largest and best-documented of the first seven ecumenical councils. The principal purpose of the council was to re-assert the teachings of the ecumenical Council of Ephesus against the teachings of Eutyches and Nestorius. Such doctrines viewed Christ's divine and human natures as separate and distinct (Nestorianism), or viewed Christ as solely divine (monophysitism). The Council of Chalcedon issued the Chalcedonian Definition, stating that Jesus is "perfect both in deity and in humanness; this selfsame one is also actually God and actually man." The council's judgments and definitions regarding the divine marked a significant turning point in the Christological debates.

Louis the Younger (830/835 – 20 January 882), sometimes called Louis the Saxon or Louis III, was the second of three sons of king Louis the German and queen Hemma, with his brothers being the elder Carloman and younger Charles. They all succeeded their father as kings in Eastern Francia on 28 August 876, in accordance with the prearranged partition, with Carloman ruling over Bavaria and the Pannonian March, Louis over Franconia, Saxony and Thuringia, and Charles over Alamannia. Louis and Charles also jointly ruled over eastern parts of Lotharingia. In 879-880, Louis acquired the western part of Lotharingia. In 880, Carloman died and his realm was inherited by Louis. By 881, the youngest brother Charles secured rule over Italy, and was crowned as emperor. Louis died in 882, without legitimate descendants, and was succeeded in all his territories, which encompassed most of East Francia, by his brother Charles.

Demetrius Zvonimir (Croatian: Dmitar Zvonimir, pronounced [dmîtar zʋônimiːr]; Old Church Slavonic: ⰸⱏⰲⱏⱀⰻⰿⰻⱃⱏ; died 1089) was a King of Croatia and Dalmatia from 1075 or 1076 until his death in 1089. Prior to that, Zvonimir also served as Ban of Croatia (1064/1070–1074). His native name was Zvonimir, but adopted the forename Demetrius at his coronation. He first served as ban in the service of King Peter Krešimir IV. Afterwards, Peter Krešimir IV appointed him duke and declared him as his heir. In 1075 or 1076, Demetrius Zvonimir succeeded to the Croatian throne through papal diplomacy. His reign is characterized as relatively peaceful, with no extensive war campaigns, focused instead on Croatia's economic and cultural development. He inherited the Croatian state at its height and ruled from the city of Knin. Medieval legends allege his assassination, but his death and succession are subjects of controversy in historiography. His reign was followed by a period of anarchy, which ended with the ascension of the Hungarian Árpád dynasty and the creation of a union with Hungary.

Isabella (French: Isabelle d'Angoulême, IPA: [izabɛl dɑ̃ɡulɛm]; c. 1186/ 1188 – 4 June 1246) was Queen of England from 1200 to 1216 as the second wife of King John, Countess of Angoulême in her own right from 1202 until her death in 1246, and Countess of La Marche from 1220 to 1246 as the wife of Count Hugh. Isabella was the only child of Aymer, Count of Angoulême, and Alice of Courtenay. In 1200, she married King John, with whom she had five children, including the future Henry III of England. After John died in 1216, Isabella remarried in 1220 to Hugh X of Lusignan, Count of La Marche, by whom she had another nine children. Some of Isabella's contemporaries, as well as later writers, claim that she formed a conspiracy against King Louis IX of France in 1241, after being publicly snubbed by his mother, Blanche of Castile, for whom she harbored a deep-seated hatred. In 1244, after the plot had failed, Isabella was accused of attempting to poison the king. To avoid arrest, she sought refuge in Fontevraud Abbey, where she died two years later, but none of this can be confirmed.

Mladen II Šubić of Bribir (Croatian: Mladen II Šubić Bribirski, Hungarian: bribiri Subics Mladen; c.1270 – c.1341), a Croatian leader and member of the Šubić noble family, was a Ban of Croatia and Lord of all of Bosnia. After succeeding his father Paul, he further consolidated the Šubić domain, and brought Stephen Kotromanić to administer Bosnia under his overlordship. His subsequent rule marked the weakening of the Šubić and ended with a mutiny of Dalmatian cities and Croatian nobility in 1322. This further led to Mladen's defeat at the Battle of Bliska and subsequent imprisonment by Charles I of Hungary, whom the Šubićs had previously brought to take the throne in Hungary. Mladen continued to develop the state and court institutions, and his de facto rule led to the further development of the chivalric culture in Croatia.

The Great Stand on the Ugra River (Russian: Великое стояние на Угре) or the Standing on the Ugra River, also known as the Battle of the Ugra, was a standoff in 1480 on the banks of the Ugra River between the forces of Akhmat Khan of the Great Horde, and Grand Prince Ivan III of the Grand Duchy of Moscow. After Ivan III stopped paying tribute to the Horde, Akhmat Khan led an army towards Moscow, leading to a standoff between the two armies on the banks of the river. Akhmat Khan waited for his Lithuanian reinforcements to arrive, but they never did, with one Mongol attempt to cross the river failing leading Akhmat Khan to retreat. Both armies departed after little fighting. Nevertheless, the outcome of the campaign corresponded to the strategic plan of the Russians to defend the capital and the border from the Tatars. In Russian historiography, it has been interpreted as the end of the "Tatar yoke" in Russia, though some historians believe that the event itself was insignificant and did not change Russo-Tatar relations. Nevertheless, the event is usually regarded as the end of nominal Tatar suzerainty over Russia. This did not end the threat from the Tatars to the Russians. For example, the Tatars under Devlet I Giray managed to burn Moscow in 1571, only to be defeated at the Battle of Molodi later that year.

The siege of Alkmaar (1573) was a turning point in the Eighty Years' War. The burghers of the Dutch city of Alkmaar held off the Spanish (who had set up their camp in Oudorp) between 21 August and 8 October 1573, with boiling tar and burning branches from their renewed city walls. On 23 September William the Silent followed up on a request by Cabeliau dating from the beginning of the siege and ordered the dikes surrounding Alkmaar to be breached, thereby flooding the polders in which the Spanish troops were camped, like the Achtermeer polder. This forced the Spanish commander, Don Fadrique, the son of the hated Alba himself, to retreat and the last Spanish soldiers left on 8 October 1573. The end of the siege is considered a turning point in the Eighty Years' War as Alkmaar was the first city to overcome a siege by the Spanish army. The garrison included a detachment of Scots soldiers who had previously tried to defend Haarlem. A first-hand account of the siege exists in the diary of Nanning van Foreest, a local city councillor. Several archaeological examinations have uncovered remains of the battle.

Jeanne Mance (French pronunciation: [ʒan mɑ̃s]; November 12, 1606 – June 18, 1673) was a French nurse and settler of New France. She arrived in New France two years after the Ursuline nuns came to Quebec. Among the founders of Montreal in 1642, she established its first hospital, the Hotel-Dieu de Montreal, in 1645. She returned twice to France to seek financial support for the hospital. After providing most of the care directly for years, in 1657 she recruited three sisters of the Religieuses hospitalieres de Saint-Joseph and continued to direct operations of the hospital. During her era, she was also known as Jehanne Mance by the French, and as Joan Mance by the English.

Stephenson's Rocket is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines. Rocket was designed and built by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne. Though Rocket was not the first steam locomotive, it was the first to bring together several innovations that produced the most advanced locomotive of its day. It is the most famous example of an evolving design of locomotives by Stephenson, and became the template for most steam engines in the following 150 years. The locomotive was displayed in the Science Museum in London until 2018, after which it was briefly exhibited at sites around the UK, ultimately at National Railway Museum in York. Between 2023 and September 2025, it was based at the Locomotion Museum in Shildon in County Durham. As of May 2026 it is now based in the National Railway Museum, York.

The Second Opium War (simplified Chinese: 第二次鸦片战争; traditional Chinese: 第二次鴉片戰爭), also known as the Second Anglo-Chinese War or Arrow War, was fought between the United Kingdom and France against the Qing dynasty of China between 1856 and 1860. It was the second major conflict in the Opium Wars, which were fought over the right to import opium to China, and resulted in a second defeat for the Qing and the forced legalisation of the opium trade. It caused many Chinese officials to believe that conflicts with the Western powers were no longer traditional wars, but part of a looming national crisis. On 8 October 1856, Qing officials seized the Arrow, a British-registered cargo ship, and arrested its Chinese sailors. The British consul, Harry Parkes, protested, upon which the viceroy of Liangguang, Ye Mingchen, delivered most of the sailors to the British on 22 October, but refused to release the rest. The next day, British gunboats shelled the city of Canton. The British government decided to seek redress from China and dispatched a naval force led by Michael Seymour, and France joined in the action, citing as its reason the murder of a French missionary in China. After coordination with each other, the British and French stormed Canton in December 1857. Ye was captured and the governor of Guangdong surrendered. The alliance then moved north to demand a treaty from the Qing court, and on 20 May 1858, captured the Taku Forts, stormed Tianjin, and threatened the capital Beijing. The Qing asked for peace, and signed the Treaty of Tientsin with Great Britain and France in 1858. However, the Xianfeng Emperor refused to ratify the treaty, after which the Qing general Sengge Rinchen restarted the war with the British and French that month. Allied reinforcements sailed from Hong Kong, and his troops were defeated. As the alliance's forces advanced toward Beijing, Parkes and a number of British and French officers were captured as hostages, and some were tortured or murdered. These events prompted Lord Elgin to order his soldiers to loot and burn the Old Summer Palace as soon as they captured Beijing. The emperor and his entourage fled to Rehe, while Prince Gong stayed to conduct the negotiations, signing the Convention of Peking with the alliance on 24 October 1860, thus ratifying the Treaty of Tientsin and bringing the Second Opium War to an end. During and after the Second Opium War, the Qing government was also forced to sign treaties with Russia, such as the Treaty of Aigun and the Convention of Peking. As a result, China ceded more than 1.5 million square kilometres (0.58 million square miles) of territory to Russia in its north-east and north-west. With the conclusion of the war, the Qing government was able to concentrate on countering the Taiping Rebellion and maintaining its rule. Among other things, the Convention of Peking ceded the Kowloon Peninsula to the British as part of Hong Kong.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by Southern 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 as president in 1860 and the growing abolitionist movement in the North. The war ended with a Union victory, dissolution of the Confederacy and the national abolition of slavery, freeing four million African Americans.

Slash-and-burn agriculture is a form of shifting cultivation in agriculture that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The process begins with cutting down the trees and woody plants in a given area. The downed vegetation, or "slash", is left out to dry, usually right before the rainiest part of the year. The biomass is then burned, resulting in a nutrient-rich layer of ash which increases soil fertility and temporarily eliminates weeds and pests. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing farmers to abandon the plot and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom.

The War of the Pacific (Spanish: Guerra del Pacífico), also known by multiple other names, was a war between Chile and a Bolivian–Peruvian alliance from 1879 to 1884. Fought over Chilean claims on coastal Bolivian territory in the Atacama Desert, the war ended with victory for Chile, which gained a significant amount of resource-rich territory from Peru and Bolivia. The war demonstrated Chile's military-technological superiority over its opponents at the time. The direct cause of the war was a nitrate taxation dispute between Bolivia and Chile, with Peru being drawn in due to its secret alliance with Bolivia. Some historians have pointed to deeper origins of the war, such as the interest of Chile and Peru in the nitrate business, a long-standing rivalry between Chile and Peru for regional hegemony, as well as the political and economical disparities between the stability of Chile and the volatility of Peru and Bolivia. In February 1878, Bolivia increased taxes on the Chilean mining company Compañía de Salitres y Ferrocarril de Antofagasta (CSFA), in violation of the Boundary Treaty of 1874 which established the border between both countries and prohibited tax increases for mining. Chile protested the violation of the treaty and requested international arbitration, but the Bolivian government, presided by Hilarión Daza, considered this an internal issue subject to the jurisdiction of the Bolivian courts. Chile insisted that the breach of the treaty would mean that the territorial borders denoted in it were no longer settled. Despite this, Hilarión Daza rescinded the license of the Chilean company, seized its assets and put it up for auction. On the day of the auction, 14 February 1879, Chile's armed forces occupied without resistance the Bolivian port city of Antofagasta, which was mostly inhabited by Chilean miners. War was declared between Bolivia and Chile on 1 March 1879, and between Chile and Peru on 5 April 1879. Battles were fought on the Pacific Ocean, in the Atacama Desert, the Peruvian deserts, and the mountainous interior of Peru. For the first five months, the war played out in a naval campaign, as Chile struggled to establish a marine resupply corridor for its forces in the world's driest desert. Afterwards, Chile's land campaign overcame the Bolivian and Peruvian armies. Bolivia withdrew after the Battle of Tacna, on 26 May 1880, leaving allied Peru fighting alone for most of the war. Chilean forces occupied Peru's capital Lima in January 1881. Remnants and irregulars of the Peruvian army waged a guerrilla war but could not prevent war-weary Peruvian factions from reaching a peace deal with Chile involving territorial cessions. Chile and Peru signed the Treaty of Ancón on 20 October 1883. Bolivia signed a truce with Chile in 1884. Chile acquired the Peruvian territory of Tarapacá, the disputed Bolivian department of Litoral (turning Bolivia into a landlocked country), and temporary control over the Peruvian provinces of Tacna and Arica. In 1904, Chile and Bolivia signed the Treaty of Peace and Friendship, which established definite boundaries. The 1929 Tacna–Arica compromise gave Arica to Chile and Tacna to Peru.

Empress Myeongseongtae (Korean: 명성태황후; Hanja: 明成太皇后; 17 November 1851 – 8 October 1895), of the Yeoheung Min clan, personal name Min Ja-yeong, commonly known as Empress Myeongseong, was the wife of Gojong, the 26th king of Joseon and the first emperor of the Korean Empire. She was queen of Joseon from 1866 until her assassination in 1895. Known as Queen Min during her lifetime, she was posthumously honored as empress following the establishment of the Korean Empire. Queen Min was of aristocratic background and in 1866 was selected by the regent Heungseon Daewongun (Grand Internal Prince Heungseon) to marry his son, the newly enthroned King Gojong. Seven years later, his chosen daughter-in-law and her Min clan forced him out of office. The Daewongun was a conservative Confucianist later implicated in an unsuccessful rebellion against his daughter-in-law's faction. He believed that isolating Joseon from all foreign contact was a means of preserving independence. She, by contrast, was a believer in gradual modernisation using Western and Chinese help. From 1873 to her assassination in 1895 she oversaw economic, military and governmental modernisation. In the 1880s and 1890s the relationship between Joseon and neighbouring Japan deteriorated. The queen was considered an obstacle by the government of Meiji Japan to its overseas expansion. She had taken a firmer stand against Japanese influence after her father-in-law's failed rebellion that intended to remove her from the political arena. Miura Gorō, the Japanese Minister to Korea, backed the faction headed by the Daewongun and directly ordered her assassination. On 8 October 1895, the Hullyŏndae regiment loyal to the Daewongun attacked Gyeongbokgung and overpowered its royal guards. The intruders then allowed a group of rōnin, specifically recruited for this purpose, to assassinate the queen. Her assassination sparked international outrage. In the winter of 1895–1896, the Japanese-backed cabinet ordered Korean men to cut off their topknots. This caused uproar, because the hairstyle was considered a badge of Korean identity. This edict and the assassination provoked nationwide protests. Gojong and the crown prince (later Emperor Sunjong) accepted refuge in the Russian legation in 1896. The anti-Japanese backlash led to the repeal of the Kabo Reform, which had introduced other measures increasing Japanese influence. In October 1897, Gojong moved to Gyeongungung. Whilst there, he proclaimed the founding of the Korean Empire and raised the status of his deceased wife to empress.

The First Balkan War lasted from October 1912 to May 1913 and involved actions of the Balkan League (the Kingdoms of Bulgaria, Serbia, Greece and Montenegro) against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior (significantly superior by the end of the conflict) and strategically disadvantaged Ottoman armies, achieving rapid success. The war was a comprehensive and unmitigated disaster for the Ottomans, who lost 83% of their European territories and 69% of their European population. As a result of the war, the League captured and partitioned almost all of the Ottoman Empire's remaining territories in Europe. Ensuing events also led to the creation of an independent Albania, which dissatisfied the Serbs. Bulgaria, meanwhile, was dissatisfied over the division of the spoils in Macedonia and attacked its former allies, Serbia and Greece, on 16 June 1913, which provoked the start of the Second Balkan War. During the war, many civilians were either killed or forced to flee their homes.

World War I, or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. One of the deadliest conflicts in history, World War I caused 15 to 22 million deaths, including those resulting from war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including machine guns, artillery, aircraft, chemical weapons, and tanks.

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 Battle of Rostov (1941) took place on the Eastern Front of World War II around Rostov-on-Don and was fought between Army Group South of Nazi Germany and the Southern Front of the Soviet Union. The battle comprised three phases: the German Sea of Azov Offensive Operation by Army Group South (General Gerd von Rundstedt) (begun on 12 September 1941), the Soviet Rostov Defensive Operation (5 November 1941 – 16 November 1941) by the Southern Front (General Yakov Timofeyevich Cherevichenko), and the Rostov Offensive Operation (27 November 1941 – 2 December 1941) executed by the same Soviet Front. After forcing their way across the Mius River on 17 November, the German forces captured 10,000 Soviet troops and took Rostov on 21 November. Six days later the Southern Front, reinforced with the newly raised 37th Army, counterattacked from the north and threatened to surround the overstretched German III Motorized Army Corps. Rundstedt then ordered a retreat to the Mius line from Rostov to prevent the encirclement. The Red Army retook Rostov on 28 November. It was the first successful major Soviet counteroffensive of the war. Hitler fired von Rundstedt on 1 December. Rundstedt's successor Walther von Reichenau confirmed the retreat order with the backing of the Army High Command Chief of Staff Franz Halder and Hitler relented (details here).

Robert Evan Brown Jr. (September 2, 1903 – November 8, 1971) was a recipient of the Medal of Honor for his actions at the Battle of Crucifix Hill, near Aachen, Germany, on October 8, 1944. He left home and joined the army in 1918, lying about his age. At the start of World War II, he was the first sergeant of the Headquarters Company of the 2nd Armored Division. He received a battlefield commission to second lieutenant and was transferred to the 1st Infantry Division in 1943. Following the death of his company commander on D-Day he assumed command of his company, Company C. Brown left the army with the rank of captain in 1952.

Three trains collided at Harrow and Wealdstone station in Wealdstone, Middlesex (now Greater London), England during the morning rush hour of 8 October 1952. The crash resulted in 112 deaths and 340 injuries, 88 of these being detained in hospital. It remains the worst peacetime rail crash in British history and the second deadliest overall after the Quintinshill rail disaster of 1915. An overnight express train from Perth crashed into the rear of a local passenger train standing at a platform at the station. The wreckage blocked adjacent lines and was struck within seconds by a double-headed express train travelling north at 60 mph (100 km/h). The Ministry of Transport report on the crash concluded that the driver of the Perth train had passed a caution signal and two danger signals before colliding with the local train. The reason for this was never established, as both the driver and the fireman of the Perth train were killed in the accident. The accident accelerated the introduction of the Automatic Warning System, and British Railways agreed to a five-year plan to install the system, which gave drivers an in-cab audible and visual warning when nearing a signal at caution, actuated by magnets between the rails.

Donald James Larsen (August 7, 1929 – January 1, 2020) was an American professional baseball pitcher. During a 15-year Major League Baseball (MLB) career, he pitched from 1953 to 1967 for seven different teams: the St. Louis Browns / Baltimore Orioles (1953–1954; 1965), New York Yankees (1955–1959), Kansas City Athletics (1960–1961), Chicago White Sox (1961), San Francisco Giants (1962–1964), Houston Colt .45's / Astros (1964–1965), and Chicago Cubs (1967). Larsen pitched the sixth perfect game in MLB history, doing so in Game 5 of the 1956 World Series. It is the only solo no-hitter and perfect game in World Series history and is one of only three no-hitters in MLB postseason history. He won the World Series Most Valuable Player Award and Babe Ruth Award in recognition of his 1956 postseason.

The Spiegel affair of 1962 (German: Spiegel-Affäre) was a political scandal in West Germany. It stemmed from the publication of an article in Der Spiegel, West Germany's weekly political magazine, about the nation's defense forces. Several Spiegel staffers were detained on charges of treason, but were ultimately released without trial. The scandal stemmed from a conflict between Franz Josef Strauss, federal minister of defense, and Rudolf Augstein, owner and editor-in-chief of Der Spiegel. The affair cost Strauss his office and, according to some commentators, put the post-war West German democracy to its first successful test of press freedom.

Ernesto "Che" Guevara de la Serna (14 May 1928 – 9 October 1967) was an Argentine Marxist revolutionary, author, guerrilla leader, diplomat, politician, and military theorist. A major figure of the Cuban Revolution, his stylized visage has become a countercultural symbol of rebellion and global insignia in popular culture. As a medical student, Guevara travelled throughout South America and was appalled by the poverty, hunger, and disease he witnessed. His burgeoning desire to help overturn what he saw as the capitalist exploitation of Latin America by the US prompted his involvement in Guatemala's social reforms under President Jacobo Árbenz, whose CIA-assisted overthrow at the behest of the United Fruit Company solidified Guevara's political ideology. In Mexico City, Guevara met Raúl and Fidel Castro, joined their 26th of July Movement, and sailed to Cuba aboard the yacht Granma with the intention of overthrowing US-backed dictator Fulgencio Batista. Guevara rose to prominence among the insurgents, was promoted to second-in-command, and played a pivotal role in the two-year guerrilla campaign which deposed the Batista regime. After the Cuban Revolution, Guevara played key roles in the new government. These included reviewing the appeals and death sentences for those convicted as war criminals during the revolutionary tribunals, instituting agrarian land reform as minister of industries, helping spearhead a successful literacy campaign, serving as president of the National Bank and instructional director for Cuba's armed forces, and traversing the globe as a diplomat on behalf of Cuban socialism. Such positions allowed him to play a central role in training the militia forces who repelled the Bay of Pigs Invasion, and bringing Soviet nuclear-armed ballistic missiles to Cuba, a decision which precipitated the 1962 Cuban Missile Crisis. Guevara was a prolific writer and diarist, composing a seminal guerrilla warfare manual, along with a best-selling memoir about his motorcycle journey. His experiences and studying of Marxism–Leninism led him to posit that the Third World's underdevelopment and dependence was an intrinsic result of imperialism, neocolonialism, and monopoly capitalism, with the only remedies being proletarian internationalism and world revolution. Guevara left Cuba in 1965 to foment continental revolutions across Africa and South America, first unsuccessfully in Congo-Kinshasa and later in Bolivia, where he was captured by CIA-assisted Bolivian forces and summarily executed. Guevara remains a revered and reviled figure, polarized in the collective imagination in biographies, memoirs, essays, documentaries, songs, and films. As a result of his perceived martyrdom, poetic invocations for class struggle, and desire to create the consciousness of a "new man" driven by moral rather than material incentives, Guevara has evolved into a quintessential icon of many leftist movements. His critics accuse him of promoting authoritarianism and endorsing violence against his opponents. Despite disagreement on his legacy, Time named him one of the 100 most influential people of the 20th century, while an Alberto Korda photograph of him, titled Guerrillero Heroico, was cited by the Maryland Institute College of Art as "the most famous photograph in the world".

The Days of Rage were a series of riots during three days in October 1969 in Chicago, organized by the emerging Weatherman faction of Students for a Democratic Society (SDS). The group planned the October 8–11 event as a "National Action" built around John Jacobs' slogan "bring the war home", which grew out of a resolution drafted by Jacobs and introduced at the October 1968 SDS National Council meeting in Boulder, Colorado. The resolution read, "The Elections Don't Mean Shit—Vote Where the Power Is—Our Power Is In The Street". It was adopted by the council, prompted by the effects of the 1968 Democratic National Convention protest activity in August and reflecting Jacobs's advocacy of direct action as political strategy.

Aleksandr Isayevich Solzhenitsyn (11 December 1918 – 3 August 2008) was a Soviet and Russian author and dissident who helped to raise global awareness of political repression in the Soviet Union, especially the Gulag prison system. He was awarded the 1970 Nobel Prize in Literature "for the ethical force with which he has pursued the indispensable traditions of Russian literature". His nonfiction work The Gulag Archipelago "amounted to a head-on challenge to the Soviet state" and sold tens of millions of copies. Solzhenitsyn was born into a family that defied the Soviet anti-religious campaign in the 1920s and remained devout members of the Russian Orthodox Church. At a young age he became an atheist and embraced Marxism–Leninism. While serving as a captain in the Red Army during World War II, Solzhenitsyn was arrested by SMERSH and sentenced to eight years in the Gulag and then internal exile for criticizing Joseph Stalin in private correspondence with another field officer. As a result of his experience in prison and the camps, he gradually became a philosophically minded Eastern Orthodox Christian. During the Khrushchev Thaw, Solzhenitsyn was released and exonerated. He started writing novels about his experiences and repression in the Soviet Union. In 1962, he published his first novel, One Day in the Life of Ivan Denisovich—an account of Stalinist repressions—with approval from Soviet leader Nikita Khrushchev. His last work to be published in the Soviet Union was Matryona's Place in 1963. After Khrushchev lost power, Soviet authorities unsuccessfully tried to discourage Solzhenitsyn from writing. His novels published in other countries included Cancer Ward in 1966, In the First Circle in 1968 and August 1914 in 1971. His three-volume non-fiction book, The Gulag Archipelago, was published in 1973. The last outraged authorities and, in 1974, he was stripped of his Soviet citizenship and flown to West Germany. He soon moved to Switzerland and then, in 1976, to Vermont in the United States with his family. He continued to write and his Soviet citizenship was restored in 1990. He returned to Russia four years later and remained there until his death in 2008.

The Yom Kippur War, also known as the 1973 Arab–Israeli War, the fourth Arab–Israeli War, the October War, or the Ramadan War (6–25 October 1973), was fought between Israel and a coalition of Arab states led by Egypt and Syria. Most of the fighting occurred in the Sinai Peninsula and the Golan Heights, territories occupied by Israel in 1967. Some combat also took place in mainland Egypt and northern Israel. The war started on 6 October 1973, when the Arab coalition launched a surprise attack across their respective frontiers during the Jewish holy day of Yom Kippur, which coincided with the 10th day of Ramadan. The United States and Soviet Union engaged in massive resupply efforts for their allies (Israel and the Arab states, respectively), which heightened tensions between the two superpowers. Egyptian and Syrian forces crossed their respective ceasefire lines with Israel, advancing into the Sinai and the Golan Heights. Egyptian forces crossed the Suez Canal in Operation Badr, establishing positions, while Syrian forces gained territory in the Golan Heights. After three days, Israel halted the Egyptian advance and pushed most of the Syrians back to the Purple Line. Israel then launched a counteroffensive into Syria, shelling the outskirts of Damascus. The Egyptian forces continued the advance into Sinai on 14 October to relieve the Syrian front which was coming under increasing pressure. Israeli forces exploited the failed Egyptian advance to breach the Suez Canal, advancing north toward Ismailia and south toward Suez to sever the Egyptian Second and Third Armies, with some units pushing west. However, their advance met fierce resistance on all fronts. Both sides accepted a UN-brokered ceasefire on 22 October, though it collapsed the day after amid mutual accusations of violations. With the renewed fighting, Israel succeeded in advancing south, materializing the threat to the Third Army's supply lines, but failed to capture Suez. A second ceasefire on 25 October officially ended the conflict. The Yom Kippur War had significant consequences. The Arab world, humiliated by the 1967 defeat, felt psychologically vindicated by its early and late successes in 1973. Meanwhile, Israel, despite battlefield achievements, recognized that future military dominance was uncertain. These shifts contributed to the Israeli–Palestinian peace process, leading to the 1978 Camp David Accords, when Israel returned the Sinai Peninsula to Egypt, and the Egypt–Israel peace treaty, the first time an Arab country recognized Israel. Egypt drifted away from the Soviet Union, eventually leaving the Eastern Bloc.

The First Intifada, also known as the First Palestinian Intifada, was a sustained uprising involving violent and non-violent protests, acts of civil disobedience, riots, and terrorist attacks carried out by Palestinian civilians and militants in the Israeli-occupied Palestinian territories and Israel. It was motivated by collective Palestinian frustration over Israel's military occupation of the West Bank and the Gaza Strip as it approached a twenty-year mark, having begun in the wake of the 1967 Arab–Israeli War. The uprising lasted from December 1987 until the Madrid Conference of 1991, though some date its conclusion to 1993, the year the Oslo Accords were signed.

The Brioni Agreement, also known as the Brioni Declaration is a document signed by representatives of Slovenia, Croatia, and Yugoslavia under the political sponsorship of the European Community (EC) on the Brijuni Islands on 7 July 1991. The agreement sought to create an environment in which further negotiations on the future of Yugoslavia could take place. However, ultimately it isolated the federal prime minister Ante Marković in his efforts to preserve Yugoslavia, and effectively stopped any form of federal influence over Slovenia. This meant the Yugoslav People's Army (JNA) would focus on combat in Croatia, creating a precedent of redrawing international borders and staking the EC's interest in resolving the Yugoslav crisis.
