The trial against Gaius Verres for corruption is opened, with Marcus Tullius Cicero as prosecutor and renowned orator Quintus Hortensius as defending lawyer.

Gaius Verres (c. 114 – 43 BC) was a Roman magistrate, notorious for his misgovernment of Sicily. His extortion of local farmers and plundering of temples led to his prosecution by Cicero, whose accusations were so devastating that Verres' defence advocate could only recommend that he should leave the country. Cicero's prosecution speeches were later published as the Verrines.
598

Goguryeo-Sui War: In response to a Goguryeo (Korean) incursion into Liaoxi, Emperor Wéndi of Sui orders his youngest son, Yang Liang (assisted by the co-prime minister Gao Jiong), to conquer Goguryeo during the Manchurian rainy season, with a Chinese army and navy.

The Goguryeo–Sui War were a series of invasions launched by the Sui dynasty of China against Goguryeo, one of the Three Kingdoms of Korea, between AD 598 and AD 614. It resulted in the defeat of the Sui and was one of the pivotal factors in the collapse of the dynasty, which led to its overthrow by the Tang dynasty in AD 618.
1265 Second Barons' War

Second Barons' War: Battle of Evesham: The army of Prince Edward (the future king Edward I of England) defeats the forces of rebellious barons led by Simon de Montfort, 6th Earl of Leicester, killing de Montfort and many of his allies.

The Second Barons' War (1264–1267) was a civil war in England between the forces of barons led by Simon de Montfort against the royalist forces of King Henry III, led initially by the king himself and later by his son, the future King Edward I. The barons sought to force the king to rule with a council of barons, rather than through his favourites. To bolster the initial success of his baronial regime, de Montfort sought to broaden the social foundations of parliament by extending the franchise to the commons for the first time. However, after a rule of just over a year, de Montfort was killed by forces loyal to the king at the Battle of Evesham. The war also involved a series of massacres of Jews by some of de Montfort's supporters (and his sons Henry and Simon) in attacks aimed at seizing and destroying evidence of baronial debts.
1320 Scone_Palace

The so-called Black Parliament at Scone tries William II de Soules and other nobles who had plotted against Robert I of Scotland and intended to place William on the Scottish throne.

Scone Palace is a Category A-listed historic house near the village of Scone and the city of Perth, Scotland. Ancestral seat of Earls of Mansfield, built in red sandstone with a castellated roof, it is an example of the Gothic Revival style in Scotland.
1327 First_War_of_Scottish_Independence

First War of Scottish Independence: James Douglas leads a raid into Weardale and almost kills Edward III of England.

The First War of Scottish Independence was the first of a series of different wars between the Kingdom of England and the Kingdom of Scotland. It lasted from the English invasion of Scotland in 1296 until the de jure restoration of Scottish independence with the Treaty of Edinburgh–Northampton in 1328. De facto independence was established in 1314 AD following an English defeat at the Battle of Bannockburn. The wars were caused by the attempts of the English kings to seize territory by claiming sovereignty over Scotland, while the Scots fought to keep both English rule and authority out of Scotland.
1578 Battle of Alcácer Quibir

Battle of Al Kasr al Kebir: The Moroccans defeat the Portuguese but both the Moroccan king Abd al-Malik and the Portuguese king Sebastian die.

Ahmad al-Mansur follows Abd al-Malik as sultan of Morocco while the death of Sebastian leads to a succession crisis in Portugal.
The Battle of Alcácer Quibir (also known as "Battle of Three Kings" (Arabic: معركة الملوك الثلاثة) or "Battle of Wadi al-Makhazin" (Arabic: معركة وادي المخازن) in Morocco) was fought in northern Morocco, near the town of Ksar-el-Kebir (variant spellings: Ksar El Kebir, Alcácer-Quivir, Alcazarquivir, Alcassar, etc.) and Larache, on 4 August 1578. A Moroccan victory, the battle has been described as "the greatest military disaster the Portuguese ever suffered in the course of their overseas expansion." It marked an end to Portuguese attempts to reconquer territories it had lost in Morocco. The combatants were the army of the deposed Moroccan Sultan Abu Abdallah Mohammed II, with his ally, the King of Portugal Sebastian I, against a large Moroccan army under the new Sultan of Morocco (and uncle of Abu Abdallah Mohammed II) Abd Al-Malik I. The Christian king Sebastian I had planned a crusade after Abu Abdallah asked him to help recover his throne. Abu Abdallah's uncle, Abd Al-Malik, had taken it from him with Ottoman support. The defeat of Portugal and disappearance of the childless Sebastian led to the end of the Aviz dynasty, and the integration of the country into the Iberian Union for 60 years under the Philippine dynasty in a dynastic union with Spain.
1693 Dom Pérignon (monk)

Date traditionally ascribed to Dom Perignon's invention of champagne; it is not clear whether he actually invented champagne, however he has been credited as an innovator who developed the techniques used to perfect sparkling wine.

Dom Pierre Pérignon (French: [dɔ̃ pjɛʁ peʁiɲɔ̃]; December 1638 – 14 September 1715), was a French Benedictine monk who made important contributions to the production and quality of champagne wine in an era when the region's wines were predominantly still red. Popular tales frequently, but erroneously, credit him with the invention of sparkling champagne, which did not become the dominant style of champagne until the mid-19th century. The famous champagne Dom Pérignon, the prestige cuvée of winery Moët & Chandon, is named after him. The remains of the monastery where he spent his adult life are now the property of that winery.
1701 Great Peace of Montreal

Great Peace of Montreal between New France and First Nations is signed.

The Great Peace of Montreal (French: La Grande paix de Montréal) was a peace treaty between New France and 39 First Nations of North America that ended the Beaver Wars. It was signed on August 4, 1701, by Louis-Hector de Callière, governor of New France, and 1300 representatives of 39 Indigenous nations. The French, allied to the Hurons and the Algonquins, brokered a peace agreement between their allies and the Six Nations of the Haudenosaunee, with over 1,300 Native Americans present, representing over 40 nations. The peace was fragile, however; although all-out war did not break out, within only three years the Odawa attacked a Haudenosaunee village near a French fort in present-day Kingston, Ontario. The warriors planted a Huron club on a dead Haudenosaunee warrior to try to provoke new fighting. This has sometimes been called the Grand Settlement of 1701, not to be confused with the unrelated Act of Settlement 1701 in England. It has often been referred to as La Paix des Braves, meaning "The Peace of the Braves".
1704 War_of_the_Spanish_Succession

War of the Spanish Succession: Gibraltar is captured by an English and Dutch fleet, commanded by Admiral Sir George Rooke and allied with Archduke Charles.

The War of the Spanish Succession, 1701 to 1714, was a European great power conflict, caused by the death of Charles II of Spain in November 1700 without children. This led to a succession crisis between Philip of Anjou, grandson of Louis XIV of France, and Archduke Charles of Austria, backed by the Grand Alliance. Related conflicts include the Great Northern War and Queen Anne's War in North America.
1781 Fourth Anglo-Dutch War

Fourth Anglo-Dutch War, a fleet of six East India Company ships sets sail from Fort Marlborough to raid the Dutch VOC factories on the West coast of Sumatra including the major port of Padang.

The Fourth Anglo-Dutch War (Dutch: Vierde Engels-Nederlandse Oorlog; 1780–1784) was a conflict between the Kingdom of Great Britain and the Dutch Republic. The war, contemporary with the American Revolutionary War (1775–1783), broke out over British and Dutch disagreements on the legality and conduct of Dutch trade with Britain's enemies in that war. Although the Dutch Republic did not enter into a formal alliance with the insurgent Americans and their French and Spanish allies, American envoy (and future president) John Adams had his credentials accepted as ambassador, establishing diplomatic relations with the Dutch Republic, making it the second European country to diplomatically recognize the United States of America in April 1782 as a sovereign nation. In October 1782, a treaty of amity and commerce was concluded as well. Most of the war consisted of a series of British operations against Dutch colonial economic interests, although British and Dutch naval forces also met once off the Dutch coast. The war ended disastrously for the Dutch and exposed the weakness of the political and economic foundations of the republic. The war exposed the decline of the Dutch Empire since the early 18th century, and further cemented Great Britain as the leading commercial power between the two empires.
1783 Mount Asama

Mount Asama erupts in Japan, killing about 1,400 people (Tenmei eruption).

The eruption causes a famine, which results in an additional 20,000 deaths.

The Japan Meteorological Agency classifies Mount Asama as rank A. It stands 2,568 metres (8,425 ft) above sea level on the border of Gunma and Nagano prefectures. It is included in 100 Famous Japanese Mountains.
1789 France

France: abolition of feudalism by the National Constituent Assembly.

France, officially the French Republic, is a country primarily located in Western Europe. Its overseas regions and territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean. Metropolitan France shares borders with Belgium and Luxembourg to the north; Germany to the northeast; Switzerland to the east; Italy and Monaco to the southeast; Andorra and Spain to the south; and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea. Its 18 integral regions—five of which are overseas—span a combined area of 632,702 km2 (244,288 sq mi), with a total population estimated at over 69.1 million in 2026. Its capital, largest city and main cultural and economic centre is Paris, with a metropolitan population of over 13 million.
1790 Tariff

A newly passed tariff act creates the Revenue Cutter Service (the forerunner of the United States Coast Guard).

A tariff, or import tax, is a duty imposed by a national government, customs territory, or supranational union on imports of goods and is paid by the importer. Exceptionally, an export tax may be levied on exports of goods or raw materials and is paid by the exporter. Besides being a source of revenue, import duties can also be a form of regulation of foreign trade and policy that burden foreign products to encourage or safeguard domestic industry. Protective tariffs are among the most widely used instruments of protectionism, along with import quotas and export quotas and other non-tariff barriers to trade.
1791 Treaty of Sistova

The Treaty of Sistova is signed, ending the Ottoman–Habsburg wars.

The Treaty of Sistova ended the last Austro-Turkish war (1787–91). Brokered by Great Britain, Prussia and the Netherlands, it was signed in Sistova (modern Svishtov) in Bulgaria on 4 August 1791. The treaty was written in French and Turkish.
1796 French_Revolutionary_Wars

French Revolutionary Wars: Napoleon leads the French Army of Italy to victory in the Battle of Lonato.

The French Revolutionary Wars were a series of sweeping military conflicts resulting from the French Revolution that lasted from 1792 until 1802. They pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The wars are divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian peninsula, the Low Countries, and the Rhineland with its very large and powerful military which had been totally mobilized for war against most of Europe with mass conscription of the vast French population. French success in these conflicts ensured military occupation and the spread of revolutionary principles over much of Europe.
1814 War_of_1812

War of 1812: The ultimately unsuccessful Siege of Fort Erie begins as British forces attempt to recapture the fort and drive American forces out of Canada.

The War of 1812 was a conflict initiated by the United States against the United Kingdom and its allies fought mainly in North America and at sea during the wider Napoleonic Wars. The United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Senate on 17 February 1815.
1821 The Saturday Evening Post

The Saturday Evening Post is published for the first time as a weekly newspaper.

The Saturday Evening Post is an American magazine published six times a year. It was first published in 1821, and published weekly from 1897 until 1963. It was published every other week until 1969. From the 1920s to the 1960s, it was one of the most widely circulated and influential magazines among the American middle class, with fiction, nonfiction, cartoons, and features that reached two million homes every week. In the 1960s, the magazine's readership began to decline. In 1969, The Saturday Evening Post folded for two years before being revived as a quarterly publication with an emphasis on medical articles in 1971. As of the late 2000s, The Saturday Evening Post is published by the Saturday Evening Post Society, which purchased the magazine in 1982. The magazine was redesigned in 2013.

1873 American Indian Wars

American Indian Wars: While protecting a railroad survey party in Montana, the United States 7th Cavalry, under Lieutenant Colonel George Armstrong Custer clashes for the first time with the Cheyenne and Lakota people near the Tongue River; only one man on each side is killed.

The American Indian Wars, also known as the American Frontier Wars, and the Indian Wars, were initially fought by European colonial empires, the United States, and briefly the Confederate States of America and Republic of Texas against various American Indian tribes in North America. These conflicts occurred from the time of the earliest colonial settlements in the 17th century until the end of the 19th century. The various conflicts resulted from a wide variety of factors, the most common being the desire of settlers and governments for tribal lands. The European powers and their colonies enlisted allied Indian tribes to help them conduct warfare against each other's colonial settlements. After the American Revolution, many conflicts were local to specific states or regions and frequently involved disputes over land use; many involved retaliatory violence. As American settlement expanded westward after the American Revolution, conflicts between the United States and Native American nations increased in scale and frequency. A major turning point came during the War of 1812, when Native confederacies in the Old Northwest and the Southern United States allied with the British against the United States. Following the war, armed resistance continued in some regions, but relations between the United States and Native nations were increasingly governed through treaties that transferred large areas of Indigenous land to the United States. Historians have noted that the United States frequently failed to uphold treaty obligations, contributing to recurring disputes and further conflict. The Indian Removal Act of 1830 authorized the president to negotiate treaties exchanging Native American lands east of the Mississippi River for lands in the west. Although the act itself provided for negotiated removals, federal and state authorities subsequently used a combination of treaties, political pressure, and coercion to relocate many Native nations from the southeastern United States to Indian Territory. The resulting removals, including the Trail of Tears, transferred millions of acres of Indigenous land to the United States and opened much of the Southeast to American settlement. As American settlement expanded across the Great Plains and the Western United States, the federal government increasingly confined Native peoples to Indian reservations through treaties, military campaigns, and congressional legislation. Native American tribes and confederacies often achieved significant military victories against American settlers and soldiers, but generally lacked the population, resources, and logistical capacity to sustain prolonged resistance against the expanding United States. Some scholars have characterized aspects of United States policies toward Native Americans, including forced removals, warfare, and reservation policies, as constituting genocide against Native Americans. Other scholars dispute the application of the term genocide to the American Indian Wars as a whole, arguing that the conflicts varied significantly across time and place.
1887 Granny_(sea_anemone)

Granny, a sea anemone, died in Edinburgh after nearly 60 years in captivity.

Her death was reported in The Scotsman and The New York Times.
Granny was the affectionate name eventually given to a beadlet sea anemone, Actinia equina, which in 1828 was taken from a rocky shore at North Berwick in Scotland by an amateur naturalist, John Dalyell. During her long life through the Victorian era, she was cared for by a series of Edinburgh naturalists. Long outliving Dalyell, this sea anemone lived alone in a jar where she gave birth to several hundred offspring before her death in 1887.
1889 Great Spokane Fire

The Great Fire of Spokane, Washington destroys some 32 blocks of the city, prompting a mass rebuilding project.

The Great Spokane Fire—known locally as The Great Fire—affected downtown Spokane, Washington (called "Spokane Falls" at the time) on August 4, 1889. It began just after 6:00 p.m. and destroyed the city's downtown commercial district. Due to technical problems with a pump station, there was no water pressure in the city when the fire started. In a desperate bid to starve the fire, firefighters began razing buildings with dynamite. Eventually winds died down and the fire exhausted of its own accord. As a result of the fire and its aftermath, virtually all of Spokane's downtown was destroyed, though only one person was killed. The cause of the fire was never determined. Theories included a cooking fire in a lunchroom, a curling iron being heated in a kerosene lamp, and a spark from a passing train.
1892 Lizzie Borden

The father and stepmother of Lizzie Borden are found murdered in their Fall River, Massachusetts home.

She will be tried and acquitted for the crimes a year later.
Lizzie Andrew Borden (July 19, 1860 – June 1, 1927) was an American woman who was tried and acquitted of the murders of her father and stepmother in Fall River, Massachusetts. No other individuals were charged with the murders. After the trial, Borden and her older sister Emma bought a house in the wealthier Highlands, or Hill District, of Fall River, where Borden lived out her life. Emma moved away after twelve years and lived in New Hampshire. Borden died of pneumonia at age 66; nine days later Emma also died. The Borden murders and 1893 trial received widespread publicity in the United States, and have remained a topic in American popular culture depicted in numerous films, theatrical productions, literary works, and even folk rhymes.
1914 World_War_I

World War I: In response to the German invasion of Belgium, Belgium and the British Empire declare war on Germany.

The United States declares its neutrality.
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.
1915 12th Army (German Empire)

World War I: The German 12th Army occupies Warsaw during the Gorlice–Tarnów Offensive and the Great Retreat of 1915.

The 12th Army (German: 12. Armee / Armeeoberkommando 12 / A.O.K. 12) was an army level command of the German Army in World War I formed in August 1915 by the redesignation of Armee-Gruppe Gallwitz. It served exclusively on the Eastern Front and was dissolved on 9 October 1916 when its commander, General der Infanterie Max von Fabeck, was transferred to 8th Army.
1921

Bolshevik–Makhnovist conflict: Mikhail Frunze declares victory over the Makhnovshchina.

The Bolshevik–Makhnovist conflict was a period of political and military conflict between the Ukrainian Soviet Socialist Republic and the Makhnovshchina, for control over southern Ukraine. The Bolsheviks aimed to eliminate the Makhnovshchina and neutralise its peasant base. In turn, the Makhnovists fought against the implementation of the Red Terror and the policy of war communism. The conflict broke out after the Red Army returned to Ukraine in early 1920, following the defeat of the White advance on Moscow. It attacked the Makhnovshchina, which at the time occupied most of southern Ukraine, and carried out a sustained attempt to pacify the region. After a brief truce, in order to ensure the final defeat of the White movement, the Red Army again attacked the Makhnovshchina in November 1920, leading to a resumption of hostilities. The conflict mainly consisted of guerrilla warfare, without conventional maneuvers or open battles. It was also highly mobile, with territory regularly changing hands between the two. The Bolsheviks largely maintained territorial control, while the Makhnovists were kept on the defensive. In this condition, the Makhnovists were not able to carry out offensives, instead mostly attacking isolated Red units. Following the implementation of the New Economic Policy and the onset of fatigue due to the conditions of the war, support for the Makhnovist insurrection began to dwindle. Despite efforts by the Makhnovists to reorganise and carry out larger offensives, by August 1921, the Makhnovshchina had effectively been wiped out. Its core around Nestor Makhno fled into exile, while a low-level insurgency persisted throughout the 1920s.
1922 Enver Pasha

Enver Pasha dies in a skirmish between the Bolshevik Red Army and Basmachi troops, to whom he had defected earlier.

İsmâil Enver Pasha (Ottoman Turkish: اسماعیل انور پاشا; Turkish: İsmail Enver Paşa; 23 November 1881 – 4 August 1922) was a Turkish military officer, revolutionary, and convicted war criminal who served as the Ottoman Empire's Minister of War from 1914 to 1918. Along with Talaat and Djemal, he was one of the Three Pashas that ruled the Ottoman Empire during World War I and one of the principal perpetrators of the Armenian, Greek, and Assyrian genocides. While stationed in Ottoman Macedonia, Enver joined the Committee of Union and Progress (CUP), an organization affiliated with the Young Turks movement that was agitating against Sultan Abdul Hamid II's despotic rule. He was a key leader of the 1908 Young Turk Revolution, which reestablished the Constitution and parliamentary democracy in the Ottoman Empire. Along with Ahmed Niyazi, Enver was hailed as "hero of the revolution". However, a series of crises in the empire, including the 31 March Incident, the Balkan Wars, and the power struggle with the Freedom and Accord Party, left Enver and the Unionists disillusioned with liberal Ottomanism. After the 1913 Ottoman coup d'état brought the CUP directly to power, Enver became War Minister, while Talaat assumed control over the civilian government. As war minister and de facto Commander-in-Chief, Enver was one of the most powerful figures in the Ottoman government. He initiated the formation of an alliance with Germany, and was instrumental in the Ottoman entry into World War I. Enver led a disastrous attack on Russian forces in the Battle of Sarikamish, after which he blamed Armenians for his defeat. Following defeat in World War I, Enver, along with other leading Unionists, escaped the Ottoman Empire. The Ottoman Military Tribunal convicted him and other Unionists and sentenced them to death in absentia for bringing the empire into World War I and organizing massacres against Greeks and Armenians. Enver sought to return during the Turkish War of Independence, but Mustafa Kemal refused to allow him to join the Turkish National Movement. He attempted to realise his pan-Turkic ideals by leading the Basmachi Revolt against the Bolsheviks in Bukhara, where he was killed in 1922. As Enver rose through the ranks of the military, he was known by increasingly esteemed titles, including Enver Efendi (انور افندی), Enver Bey (انور بك), and finally Enver Pasha. "Pasha" was the honorary title granted to Ottoman military officers upon promotion to the rank of Mirliva (major general). In the Republic of Turkey, he became a controversial figure due to his rivalry with Kemal, but his image was rehabilitated in the 1990s by Turkish President Süleyman Demirel, who praised his contributions to Turkish nationalism. In 1996, his remains were repatriated and reburied in Turkey.
1924 Mexico–Russia relations

Diplomatic relations between Mexico and the Soviet Union are established.

The nations Mexico and Russia initially established diplomatic relations in 1890. In 1924, Mexico recognized and established diplomatic relations with the Soviet Union. In 1930, Mexico broke diplomatic relations with the USSR and granted asylum to Leon Trotsky (who was later killed in Mexico City in 1940). In 1943, Mexico and the USSR re-established diplomatic relations. After the dissolution of the union, Mexico once again established diplomatic relations with the current Russian Federation in 1992. Both nations are members of the Asia-Pacific Economic Cooperation, G-20 major economies and the United Nations.
1936

Prime Minister of Greece Ioannis Metaxas suspends parliament and the Constitution and establishes the 4th of August Regime.

This is a list of the heads of government of the modern Greek state, from its establishment during the Greek War of Independence to the present day. Although various official and semi-official appellations were used during the early decades of independent statehood, the title of prime minister has been the formal designation of the office at least since 1843. On dates, Greece officially adopted the Gregorian calendar on 16 February 1923. All dates prior to that, unless specifically denoted, are Old Style.
1944 The_Holocaust

The Holocaust: A tip from a Dutch informer leads the Gestapo to a sealed-off area in an Amsterdam warehouse, where they find and arrest Jewish diarist Anne Frank, her family, and four others.

The Holocaust, known in Hebrew as the Shoah, was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered around six million Jews across German-occupied Europe, approximately two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, Chełmno and Majdanek death camps in occupied Poland. Concurrent Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups, such as the Romani and Soviet POWs.
1946 1946_Dominican_Republic_earthquake

1964 Civil_rights_movement

Civil rights movement: Civil rights workers Michael Schwerner, Andrew Goodman and James Chaney are found dead in Mississippi after disappearing on June 21.

The civil rights movement was a social movement in the United States from 1954 to 1968 which aimed to abolish legalized racial segregation, discrimination, and disenfranchisement in the country, which most commonly affected African Americans. The movement had origins in the Reconstruction era in the late 19th century, and modern roots in the 1940s and in Mahatma Gandhi's nonviolent movement in India. After years of nonviolent protests and civil disobedience campaigns, the civil rights movement achieved many of its legislative goals in the 1960s, during which it secured new protections in federal law for the civil rights of all Americans, including the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Civil Rights Act of 1968.
1964 Gulf_of_Tonkin_incident

Second Gulf of Tonkin Incident: U.S.

destroyers USS Maddox and USS Turner Joy mistakenly report coming under attack in the Gulf of Tonkin.
The Gulf of Tonkin incident refers to a naval confrontation in the Gulf of Tonkin off the coast of North Vietnam, which led to the United States engaging more directly in the Vietnam War. On 2 August 1964 there was a clash between a destroyer of the United States Navy that was collecting signals intelligence close to North Vietnamese waters, and three North Vietnamese naval vessels.

It is the worst economic crisis in Venezuela's history and considered by some sources as more severe than the Great Depression in the United States, the 1985–1994 Brazilian economic crisis, or the 2008–2009 hyperinflation in Zimbabwe. In 2019, the Institute of International Finance called it the single largest economic collapse outside of war in 45 years. Writers have compared aspects, such as unemployment and GDP contraction, to Bosnia and Herzegovina after the 1992–95 Bosnian War, and those in Russia, Cuba and Albania following the Revolutions of 1989.
