July 20 in History

Pope Hormisdas (; c. 450 – 6 August 523) was the bishop of Rome from 20 July 514 to his death on 6 August 523. His papacy was dominated by the Acacian schism, started in 484 by Acacius of Constantinople's efforts to placate the non-Chalcedonians. His efforts to resolve this schism were successful, and on 28 March 519, the reunion between Constantinople and Rome was ratified in the cathedral of Constantinople before a large crowd.

911 (CMXI) was a common year starting on Tuesday of the Julian calendar.

Richard I (8 September 1157 – 6 April 1199), known as Richard the Lionheart or Richard Cœur de Lion (Old Norman French: Quor de Lion) because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father. By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was an important Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France. Despite achieving several victories against his Muslim counterpart, Saladin, he was ultimately forced to end his campaign without retaking Jerusalem. Richard probably spoke both French and Occitan, and based on the testimony of Roger of Howden, most likely understood Middle English. He was born in England, where he spent his childhood; before becoming Duke of Aquitaine, however, he lived most of his adult life in the Duchy of Aquitaine, in the southwest of France. Following his accession to the crown of England, he spent very little time, perhaps as little as six months, in England. Most of his reign was spent on Crusade, in captivity, or actively defending the French portions of the Angevin Empire. Though regarded as a model king and a paragon of chivalry during the four centuries after his death and viewed as a pious and chivalrous hero by his subjects, he was later perceived by historians as a ruler who treated the kingdom of England merely as a source of revenue for his armies rather than a land entrusted to his stewardship. This "Little England" view of Richard has come under increasing scrutiny from modern scholars who regard it as anachronistic and point out his wider continental responsibilities as a ruler. Richard I is an enduring iconic figure both in England and in France.

The Treaty of San Germano was signed on 23 July 1230 at San Germano, present-day Cassino, ending the War of the Keys that had begun in 1228. The parties were Pope Gregory IX and Frederick II, king of Sicily and Holy Roman emperor. On 28 August at Ceprano, the peace was finalized with the readmission of the excommunicated Frederick into the church. The negotiations for the treaty, initiated by Frederick, began in November 1229. The Lombard League, an ally of Gregory, objected to the process. The intercession of major German princes, especially Duke Leopold VI of Austria and Grand Master Hermann von Salza, was necessary to move things forward. The most important negotiator on the papal side was Cardinal Thomas of Capua, although Gregory's actual representative at the signing was Guala de Roniis. In territorial terms, the treaty essentially restored the status quo ante bellum. Frederick recognized the Papal State and Gregory recognized Frederick as king of Sicily and emperor unimpaired. A general amnesty was issued. The biggest concession was Frederick's surrender of his special rights over the church in Sicily. Nevertheless, the treaty has often been regarded as a victory for the emperor.

The English people are an ethnic group and nation native to England, who speak the English language, a West Germanic language, and share a common ancestry, history, and culture. The English identity began with the Anglo-Saxons, when they were known as the Angelcynn, meaning "Angle kin" or "English people". Their ethnonym is derived from the Angles, one of the Germanic peoples who settled in Britain around the 5th century AD.

The Imjin War (Korean: 임진왜란; Hanja: 壬辰倭亂) was a series of two Japanese invasions of Korea: an initial invasion in 1592 also individually called the "Imjin War", a brief truce in 1596 between the conflicts, followed by a second invasion in 1597 called the Chŏngyu War (정유재란; 丁酉再亂). The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces. The invasions were launched by Toyotomi Hideyoshi to conquer Korea, and Japan quickly occupied large portions of the country. However, reinforcements from Ming China and disruption of Japanese supply fleets by the Joseon Navy forced the Japanese forces to withdraw from the northern provinces. Thereafter, Joseon civilian militias engaged in guerrilla warfare against the occupying Japanese forces, and supply difficulties hampered both sides. At that point, the conflict ground to a stalemate. The first phase of the conflict ended in 1596. Japan invaded Korea again in 1597, and gained initial successes on land; similar to the previous campaign, the invading forces were later halted and withdrew to the peninsula's southern coastal regions. Ming and Joseon forces were unable to dislodge the Japanese from these positions. Both sides again became locked in a ten-month-long military stalemate. However, Toyotomi Hideyoshi later died and the Japanese were defeated at the Battle of Noryang, effectively ending the war. The invading forces were ordered to withdraw to Japan by the new governing Council of Five Elders soon thereafter. Peace negotiations between the parties followed, and continued for several years, ultimately resulting in the normalization of relations.

Oulu is the third northernmost city in the world with a population of over 100,000, after Murmansk and Norilsk in Russia. Due to its large population and geopolitical, economic and cultural-historical position, Oulu has been called the "capital of Northern Finland". Oulu is also considered one of Europe's "living labs", where residents experiment with new technologies (such as NFC tags and ubi-screens) on a community-wide scale. Although only in the top 2% of universities, the University of Oulu is regionally renowned in the field of information technology. Oulu has also been very successful in recent city image surveys; in a study published by the Finnish Economic Survey in 2008, Oulu received the best image rating among large cities in the country, including ratings from respondents in all provinces. In the 2023 T-Media survey, Oulu was tied with Kuopio as the second most attractive city in Finland, while Tampere was ranked first. In 2025, Oulu had the cleanest air quality among all European cities according to European Environment Agency (EEA). Once known for wood tar and salmon, Oulu has become a major high-tech centre, particularly in IT and wellness technology. In 2024, Oulu placed third in the European Commission’s Capital of Innovation Awards (iCapital) in the Rising Innovative Cities category. Other important industries include wood processing, chemicals, pharmaceuticals, paper and steel. Oulu has been selected as the European Capital of Culture for 2026 together with Trenčín, Slovakia.

The Seventh Ottoman–Venetian War was fought between the Republic of Venice and the Ottoman Empire between 1714 and 1718. It was the last conflict between the two powers, and ended with an Ottoman victory and the loss of Venice's major possession in the Greek peninsula, the Peloponnese (Morea). Where the Barbary States intervention to support the Ottomans. Venice was saved from a greater defeat by the intervention of Austria in 1716 and by some naval success. The war ended with Treaty of Passarowitz in 1718.

Pierre Gaultier de Varennes, sieur de La Vérendrye (17 November 1685 – 5 December 1749) was a military officer, fur trader, and explorer. In the 1730s, he and his four sons explored the area west of Lake Superior and established trading posts there. They were part of a process that added Western Canada to the original New France territory that was centred along the Saint Lawrence basin. He was the first known European to reach present-day North Dakota and the upper Missouri River in the United States. In the 1740s, two of his sons crossed the prairie as far as present-day Wyoming, United States, and were the first Europeans to see the Rocky Mountains north of New Mexico.

Tekle Giyorgis I (Ge'ez: ተክለ ጊዮርጊስ; c. 1751 – 12 December 1817), throne name Feqr Sagad, was Emperor of Ethiopia intermittently between 20 July 1779 and June 1800, and a member of the Solomonic dynasty. He was the youngest son of Yohannes II and Woizoro Sancheviyer, and the brother of Tekle Haymanot II. According to Sven Rubenson, who described Tekle Giyorgis as the last emperor to exercise authority on his own, "It is not without justification that he has in Ethiopian tradition received the nickname Fiṣame Mengist, 'the end of the Kingdom'". Tekle held multiple separated reigns due to quarrels against his rivals for the crown, he continually pursued to restore himself to the throne in his later life.

Joseph Nicéphore Niépce was a French inventor and one of the pioneers of photography. Niépce developed heliography, a technique he used to create the world's oldest surviving products of a photographic process. In the mid-1820s, he used a primitive camera to produce the oldest surviving photograph of a real-world scene. Among Niépce's other inventions was the Pyréolophore, one of the world's first internal combustion engines, which he conceived, created, and developed with his older brother Claude Niépce.

The Seneca ( SEN-ik-ə; Seneca: Onödowaʼga꞉ʼ IPA: [onɔ̃dowɑʔgɑːʔ], lit. 'Great Hill People') are a group of Indigenous Iroquoian-speaking people who historically lived south of Lake Ontario, one of the five Great Lakes in North America. Their nation was the farthest to the west within the Six Nations or Haudenosaunee (Iroquois League) in New York before the American Revolution. For this reason, they are called "The Keepers of the Western Door". In the 21st century, more than 10,000 Seneca live in the United States, which has three federally recognized Seneca tribes. Two of them are centered in New York: the Seneca Nation of Indians, with five territories in western New York near Buffalo; and the Tonawanda Seneca Nation. The Seneca-Cayuga Nation is in Oklahoma, where their ancestors were relocated from Ohio during the Indian Removal. Approximately 1,000 Seneca live in Canada, where they are enrolled in the Konadaha Seneca First Nation and Niharondasa Seneca First Nation at the Six Nations of the Grand River near Brantford, Ontario. They are descendants of Seneca who resettled there after the American Revolution, as they had been allies of the British and forced to cede much of their lands.

The Seneca Falls Convention was the first women's rights convention. Its organizers advertised it as "a convention to discuss the social, civil, and religious condition and rights of woman". Held in the Wesleyan Chapel of the town of Seneca Falls, New York, it spanned two days over July 19–20, 1848. Attracting widespread attention, it was soon followed by other women's rights conventions, including the Rochester Women's Rights Convention in Rochester, New York, two weeks later. In 1850 the first in a series of annual National Women's Rights Conventions met in Worcester, Massachusetts. Female Quakers local to the area organized the meeting along with Elizabeth Cady Stanton, who was not a Quaker. They planned the event during a visit to the area by Philadelphia-based Lucretia Mott. Mott, a Quaker, was famous for her oratorical ability, which was rare for non-Quaker women during an era in which women were often not allowed to speak in public. The meeting comprised six sessions including a lecture on law, a humorous presentation, and multiple discussions about the role of women in society. Stanton and the Quaker women presented two prepared documents, the Declaration of Sentiments and an accompanying list of resolutions, to be debated and modified before being put forward for signatures. A heated debate sprang up regarding women's right to vote, with many – including Mott – urging the removal of this concept, but Frederick Douglass, who was the convention's sole African American attendee, argued eloquently for its inclusion, and the suffrage resolution was retained. Exactly 100 of approximately 300 attendees signed the document, mostly women. The convention was seen by some of its contemporaries, including featured speaker Mott, as one important step among many others in the continuing effort by women to gain for themselves a greater proportion of social, civil and moral rights, while it was viewed by others as a revolutionary beginning to the struggle by women for complete equality with men. Stanton considered the Seneca Falls Convention to be the beginning of the women's rights movement, an opinion that was echoed in the History of Woman Suffrage, which Stanton co-wrote. The convention's Declaration of Sentiments became "the single most important factor in spreading news of the women's rights movement around the country in 1848 and into the future", according to Judith Wellman, a historian of the convention. By the time of the National Women's Rights Convention of 1851, the issue of women's right to vote had become a central tenet of the United States women's rights movement. These conventions became annual events until the outbreak of the American Civil War in 1861.

The Battle of Peachtree Creek was fought in Georgia on July 20, 1864, as part of the Atlanta campaign in the American Civil War. It was the first major attack by Lt. Gen. John Bell Hood since taking command of the Confederate Army of Tennessee. The attack was against Maj. Gen. William T. Sherman's Union army, which was perched on the doorstep of Atlanta. The main armies in the conflict were the Union Army of the Cumberland, commanded by Maj. Gen. George Henry Thomas and two corps of the Confederate Army of Tennessee.

The Austro-Prussian War (German: Preußisch-Österreichischer Krieg) was fought in 1866 between the Austrian Empire and the Kingdom of Prussia, with each also being aided by various allies within the German Confederation. Prussia had also allied with the Kingdom of Italy, linking this conflict to the Third Independence War of Italian unification. The Austro-Prussian War was part of the wider rivalry between Austria and Prussia, and resulted in Prussian dominance over the German states, having confirmed Prussia's superiority in military organization and technology over Austria at the time. The major result of the war was a shift in power among the German states away from Austrian and towards Prussian hegemony. It resulted in the abolition of the German Confederation and its partial replacement by the unification of all of the northern German states in the North German Confederation that excluded Austria and the other southern German states, a Kleindeutsches Reich. The war also resulted in the Italian annexations of the Austrian realm of Venetia.

British Columbia is the westernmost province of Canada. Situated in the Pacific Northwest between the Pacific Ocean and the Rocky Mountains, the province has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts, and grassy plains. British Columbia borders the province of Alberta to the east; the territories of Yukon and Northwest Territories to the north; the US states of Washington, Idaho, and Montana to the south; and Alaska to the northwest. With an estimated population of 5.68 million in 2025, it is Canada's third-most populous province. The capital of British Columbia is Victoria, while the province's largest city is Vancouver. Vancouver and its suburbs together make up the third-largest metropolitan area in Canada, with the 2021 census recording 2.6 million people in Metro Vancouver. British Columbia is Canada's third-largest province by total area, after Quebec and Ontario.

The Ford Motor Company (commonly known as Ford, sometimes abbreviated as FoMoCo) is an American multinational automobile manufacturer headquartered in Dearborn, Michigan, United States. It was founded by Henry Ford and incorporated on June 16, 1903. The company sells automobiles and commercial vehicles under the Ford brand, and luxury cars under its Lincoln brand. The company is listed on the New York Stock Exchange under the single-letter ticker symbol F and is controlled by the Ford family. They have minority ownership but a plurality of the voting power. Ford introduced methods for large-scale manufacturing of cars and large-scale management of an industrial workforce using elaborately engineered manufacturing sequences typified by moving assembly lines. By 1914, these methods were known around the world as Fordism. Ford's former British subsidiaries Jaguar and Land Rover, acquired in 1989 and 2000, respectively, were sold to the Indian automaker Tata Motors in March 2008. Ford owned the Swedish automaker Volvo from 1999 to 2010. In the third quarter of 2010, Ford discontinued the Mercury brand, under which it had marketed middle priced cars in the United States, Canada, Mexico, and the Middle East since 1938. Ford is the second-largest American-based automaker, behind General Motors, and the sixth-largest in the world, behind Toyota, Volkswagen Group, Hyundai Motor Group, Stellantis, and General Motors, based on 2022 vehicle production. The company went public in 1956 but the Ford family, through special Class B shares, retain 40 percent of the voting rights. During the 2008–2010 automotive industry crisis, the company struggled financially but did not have to be rescued by the federal government, unlike the other two major US automakers. Ford Motors has since returned to profitability, and was the eleventh-ranked overall American-based company in the 2018 Fortune 500 list, based on global revenues in 2017 of $156.7 billion. In 2023, Ford produced 4.4 million automobiles, and employed about 177,000 employees worldwide. The company operates joint ventures in China (Changan Ford and Jiangling Ford), Taiwan (Ford Lio Ho), Thailand (AutoAlliance Thailand), and Turkey (Ford Otosan). Ford owns a 32% stake in China's Jiangling Motors.

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 resulted in an estimated 15 to 22 million deaths, including those in war crimes and genocides. The war also helped spread the Spanish flu pandemic. The conflict saw important developments in weaponry, including the first large-scale use of machine guns, artillery, aircraft, chemical weapons, and tanks.

The League of Nations was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference that ended the First World War. The main organisation ceased operations on 18 April 1946 when many of its components were relocated into the new United Nations (UN) which was created in the aftermath of the Second World War. The League of Nations was the precursor organisation to the United Nations.

The 1932 Prussian coup d'état or Preußenschlag (German pronunciation: [ˈpʁɔʏsənˌʃlaːk]; lit. 'Prussian hit') took place on 20 July 1932, when Reich President Paul von Hindenburg, at the request of Franz von Papen, then Reich Chancellor of Germany, replaced the legal government of the Free State of Prussia with von Papen as Reich Commissioner. A second decree the same day transferred executive power in Prussia to the Reich Minister of the Armed Forces Kurt von Schleicher and restricted fundamental rights. Papen had two rationales for the coup. One was that the 1932 Prussian state election had left a divided parliament with no viable possibilities for a coalition. This led to a caretaker government under the coalition that had held power before the election, with no clear path to replacing it with a new governing coalition. The second and major rationale was that in parts of Prussia there were violent street demonstrations and clashes taking place that Papen said the caretaker government could not control. The immediate result was elimination of the last resistance in Prussia to Papen's attempt to establish a "New State", essentially a precursor to a restored monarchy. However, the coup also weakened the federalist Constitution of the Weimar Republic and ultimately facilitated the centralization of the Reich under Adolf Hitler after he was appointed chancellor in January 1933.

Minneapolis is a city in Hennepin County, Minnesota, United States, and its county seat. With a population of 429,954 as of the 2020 census, it is the state's most populous city.

Minneapolis, Saint Paul, and the surrounding area are collectively known as the Twin Cities, a metropolitan area with 3.69 million residents. Minneapolis is built on an artesian aquifer on relatively flat terrain and is known for cold, snowy winters and hot, humid summers. Nicknamed the "City of Lakes", Minneapolis is abundant in water, with thirteen lakes, wetlands, the Mississippi River, creeks, and waterfalls. The city's public park system is connected by the Grand Rounds National Scenic Byway.

The 1934 West Coast waterfront strike (also known as the 1934 West Coast longshoremen's strike, as well as a number of variations on these names) began on May 9, 1934, when longshoremen in every U.S. West Coast port walked out. It lasted 83 days. Organized by the International Longshoremen's Association (ILA), the strike peaked with the death of two workers on "Bloody Thursday" and the subsequent San Francisco General Strike, which stopped all work in the major port city for four days, and led ultimately to the settlement of the West Coast Longshoremen's Strike. The result of the strike was the unionization of all of the West Coast ports of the United States. The San Francisco General Strike of 1934, along with the Toledo Auto-Lite Strike of 1934 led by the American Workers Party and the Minneapolis Teamsters Strike of 1934 led by the Communist League of America, were catalysts for the rise of industrial unionism in the 1930s, much of which was organized through the Congress of Industrial Organizations.

KLM Royal Dutch Airlines, or simply KLM (an abbreviation for their official name Koninklijke Luchtvaart Maatschappij N.V. [ˈkoːnɪŋkləkə ˈlʏxtfaːrt ˌmaːtsxɑˈpɛi ˌɛnˈveː], lit. 'Royal Aviation Company'), is the flag carrier of the Netherlands. KLM's headquarters are located in Amstelveen, with its hub at nearby Amsterdam Airport Schiphol. It is a subsidiary of the Air France–KLM group and a member of the SkyTeam airline alliance. Founded in 1919, KLM is the oldest operating airline still using its original name, having gone through significant changes in its ownership and legal structure over its history, including a period of majority government ownership. The company had a fleet of 110 aircraft (excluding subsidiaries) and 35,488 employees as of 2021. KLM operates scheduled passenger and cargo services to 171 destinations. Historically, KLM established some of the earliest scheduled intercontinental flights, including interwar routes to the Dutch East Indies (now Indonesia). In 2004, the airline merged with Air France to form the Air France–KLM holding company, though both carriers continue to operate under their separate brand identities. The airline's mainline network is supported by several subsidiaries. Regional European feeder routes are operated by KLM Cityhopper, while low-cost services are managed by Transavia. Freight operations are handled by KLM Cargo and its subsidiary Martinair.

The (Montreux) Convention regarding the Regime of the Straits, often known simply as the Montreux Convention, is an international agreement governing the Bosporus and Dardanelles straits in Turkey. Signed on 20 July 1936 at the Montreux Palace in Switzerland, it went into effect on 9 November 1936, addressing the long running Straits Question over who should control the strategically vital link between the Black and Mediterranean seas. The Montreux Convention regulates maritime traffic through the Bosporus and Dardanelles straits in Turkey. It guarantees "complete freedom" of passage for all civilian vessels in times of peace. In peacetime, military vessels are limited in number, tonnage and weaponry, with specific provisions governing their mode of entry and duration of stay. If they want to pass through the Strait, warships must provide advance notification to the Turkish authorities, which, in turn, must inform the parties to the convention. In wartime, if Turkey is not involved in the conflict, warships of the nations at war may not pass through the Straits, except when returning to their base. When Turkey is at war, or feels threatened by a war, it may take any decision about the passage of warships as it sees fit. While it was designed for a particular geopolitical context, and remains unchanged since its adoption, the Montreux Convention has endured as a "solid example of a rules-based international order", since most of its terms are still followed.

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

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

The Israel–Syria Mixed Armistice Commission (ISMAC) was the United Nations commission for observing the armistice between Israel and Syria after the 1948 Arab–Israeli War, as part of the Mixed Armistice Commissions (MAC). The fourth and last truce agreement, the 1949 armistice agreement, was signed between Israel and Syria on 20 July 1949 on Hill 232 near Mahanayim, ending the formal conflict in the former Mandatory Palestine. The Israeli side was represented by Lieutenant Colonel Mordechai Maklef, Yehoshua Penman and Shabtai Rosenne, while the Syrian side was represented by Colonel Fawzi Selo, Lieutenant Colonel Mohamed Nasser and Captain Afif Sizri. While the armistice agreements with Syria concluded the 1948 Arab–Israeli War, they did not mark the end of the Arab–Israeli conflict.

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.

USS Constitution, also known as Old Ironsides, is a three-masted wooden-hulled heavy frigate of the United States Navy. She is the second oldest naval vessel still in commission, and the oldest still afloat. She was launched in 1797, one of six original frigates authorized for construction by the Naval Act of 1794 and the third constructed. The name "Constitution" was among ten names submitted to President George Washington by Secretary of War Timothy Pickering in March or May for the frigates that were to be constructed. Joshua Humphreys designed the frigates to be the young Navy's capital ships, and so Constitution and her sister ships were larger and more heavily armed and built than standard frigates of the period. She was built at Edmund Hartt's shipyard in the North End of Boston, Massachusetts. Her first duties were to provide protection for American merchant shipping during the Quasi-War with France and to defeat the Barbary pirates in the First Barbary War.

The war lasted almost 14 years and culminated in the fall of the Assad regime in December 2024. Many sources regard this as the end of the civil war even though clashes have continued into 2026.
