351 Jewish revolt against Constantius Gallus

The Jewish revolt against Constantius Gallus breaks out after his arrival at Antioch.

In 351–352, the Jews of the Roman province of Syria Palaestina revolted against the rule of Constantius Gallus, brother-in-law of Emperor Constantius II and caesar of the eastern part of the Roman Empire. The revolt, which occurred during the Roman civil war of 350–353, was crushed by Gallus' general Ursicinus. The rebellion was led by Isaac of Diocaesarea (also known as Isaac of Sepphoris), aided by a certain Patricius and had its epicentre in the town of Diocaesarea (the Greco-Roman referent for Sepphoris). Jerome records that the revolt began with a night attack on the Roman garrison, which was destroyed, and allowed the Jews to procure the necessary weapons. According to the 9th-century author Theophanes the Confessor, the rebels subsequently killed the people of different ethnicities, pagan Greek Hellenes and Samaritans.
558 Constantinople

In Constantinople, the dome of the Hagia Sophia collapses, twenty years after its construction.

Justinian I immediately orders that the dome be rebuilt.
Constantinople, the modern Istanbul, was the capital of the Roman and Byzantine Empire from 330 until its takeover by the Ottoman Empire in 1453. After this, it continued to function as the Ottoman capital Konstantiniyye until the abolition of the Ottoman sultanate in 1922. It was located at the core of the modern city of Istanbul, on a peninsula at the southeastern tip of Thrace in Europe; with the Bosporus strait and the ancient cities of Chalcedon and Chrysopolis in Bithynia, Anatolia to the east; the Golden Horn and the citadel of Galata (Pera) to the north; the Sea of Marmara to the south; and the Princes' Islands to the southeast.
1104

The Seljuk emirs of Mosul and Mardin defeat the Crusader States of Antioch and Edessa.

The Seljuk Empire, or the Great Seljuk Empire, was a high medieval, culturally Turco-Persian empire established and ruled by the Qïnïq branch of Oghuz Turks. The empire spanned a total area of 3.9 million square kilometres from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south, and it spanned the time period 1037–1308, though Seljuk rule beyond the Anatolian peninsula ended in 1194.
1190 Frederick Barbarossa

The Crusader army of emperor Frederick Barbarossa defeats an army of the Rum Seljuks in the battle of Philomelion.

Frederick Barbarossa (December 1122 – 10 June 1190), also known as Frederick I (German: Friedrich; Italian: Federico), was the Holy Roman Emperor from 1155 until his death in 1190. He was elected King of Germany in Frankfurt on 4 March 1152 and crowned in Aachen on 9 March 1152. He was crowned King of Italy on 24 April 1155 in Pavia and emperor by Pope Adrian IV on 18 June 1155 in Rome. Two years later, the term sacrum ("holy") first appeared in a document in connection with his empire. He was later formally crowned King of Burgundy, at Arles on 30 June 1178. His nickname of Barbarossa (meaning "Red Beard" in Italian) "was first used by the Florentines only in 1298 to differentiate the emperor from his grandson, Frederick II ... and was never employed in medieval Germany" (the colour red was "also associated in the Middle Ages with malice and a hot temper"; in reality, Frederick's hair was "blond", although his beard was described by a contemporary as "reddish"). In German, he was known as Kaiser Rotbart, which in English means "Emperor Redbeard". The prevalence of the Italian nickname, even in later German usage, reflects the centrality of the Italian campaigns under his reign, and "remains to this day one of the [most] powerful historical monikers." Frederick was by inheritance Duke of Swabia (1147–1152, as Frederick III) before his imperial election in 1152. He was the son of Duke Frederick II of the Hohenstaufen dynasty and Judith, daughter of Henry IX, Duke of Bavaria, from the rival House of Welf. Frederick, therefore, descended from the two leading families in Germany, making him an acceptable choice for the Empire's prince-electors. Frederick joined the Third Crusade and opted to travel overland to the Holy Land. In 1190, Frederick drowned attempting to cross the Saleph River, leading to most of his army abandoning the Crusade before reaching Acre. Historians consider him among the Holy Roman Empire's greatest medieval emperors. He combined qualities that made him appear almost superhuman to his contemporaries: his longevity, his ambition, his extraordinary skills at organization, his battlefield acumen, and his political perspicacity. His contributions to Central European society and culture include the re-establishment of the Corpus Juris Civilis, or the Roman rule of law, which counterbalanced the papal power that had dominated the German states since the conclusion of the Investiture controversy. Due to his popularity and fame, in the 19th and early 20th centuries, he was used as a political symbol by many movements and regimes: the Risorgimento, the Wilhelmine government in Germany (especially under Emperor Wilhelm I), and the Nazi movement (Operation Barbarossa, Barbarossa decree) resulting in mixed legacies.
1274

In France, the Second Council of Lyon opens; it ratified a decree to regulate the election of the Pope.

The Second Council of Lyon was the fourteenth ecumenical council of the Roman Catholic Church, convoked on 31 March 1272 and convened in Lyon, Kingdom of Arles (in modern France), in 1274. Pope Gregory X presided over the council, called to act on a pledge by Byzantine emperor Michael VIII to reunite the Eastern church with the West. The council was attended by about 300 bishops, 60 abbots and more than a thousand prelates or their procurators among whom were the representatives of the universities. Due to the great number of attendees, those who had come to Lyon without being specifically summoned were given "leave to depart with the blessing of God" and of the Pope. Among others who attended the council were James I of Aragon, the ambassador of the Emperor Michael VIII Palaiologos with members of the Greek clergy and the ambassadors of Abaqa Khan of the Ilkhanate. Thomas Aquinas had been summoned to the council, but died en route at Fossanova Abbey. Bonaventure was present at the first four sessions but died at Lyon on 15 July 1274. As at the First Council of Lyon, Thomas Cantilupe was an English attendee and a papal chaplain. In addition to Aragon, which James represented in person, representatives of the kings of Germany, England, Scotland, France, the Spains and Sicily were present, with procurators also representing the kingdoms of Norway, Sweden, Hungary, Bohemia, Poland, and the "realm of Dacia". In the procedures to be observed in the council, for the first time, the nations appeared as represented elements in an ecclesiastical council, as they had already become represented in the governing of medieval universities. That innovation marks a stepping-stone towards the acknowledgment of coherent ideas of nationhood, which were in the process of creating the European nation-states. The main topics discussed at the council were the conquest of the Holy Land and the union of the Eastern and Western Churches. The first session took place on 7 May 1274 and was followed by five additional sessions on 18 May 1274, 4 or 7 June 1274, 6 July 1274, 16 July 1274, and 17 July 1274. By the end of the council, 31 constitutions were promulgated. In the second session, the fathers approved the decree Zelus fidei, which contained no juridical statutes but rather summed up constitutions about the perils of the Holy Land, the means for paying for a proposed crusade, the excommunication of pirates and corsairs and those who protected them or traded with them, a declaration of peace among Christians, a grant of an indulgence for those willing to go on crusade, restoration of communion with the Greeks, and the definition of the order and procedure to be observed in the council. The Greeks conceded on the issue of the Filioque (two words added to the Nicene Creed), and union was proclaimed, but the union was later repudiated by Andronicus II, heir to Michael VIII. The council also recognised Rudolf I as King of the Romans and ended the interregnum.
1342 Avignon

In Avignon, France, Cardinal Pierre Roger is elected Pope and takes the name Clement VI.

Avignon is the prefecture of the Vaucluse department in the Provence-Alpes-Côte d'Azur region of southern France. Located on the left bank of the river Rhône, the commune has a population of 92,188 (2023), with about 16,000 living in the ancient town centre enclosed by its medieval walls.
1487 Siege of Málaga (1487)

The Siege of Málaga commences during the Spanish Reconquista.

The 1487 siege of Málaga was an action during the Reconquest of Spain in which the Catholic Monarchs of Spain conquered the city of Mālaqa from the Emirate of Granada. The siege lasted about four months. It was the first conflict in which ambulances, or dedicated vehicles for the purpose of carrying injured persons, were used. Geopolitically, the loss of the emirate's second largest city—after Granada itself—and its most important port was a major loss for Granada. Most of the surviving population of the city were enslaved or put to death by the conquerors.
1544 Burning of Edinburgh

The Burning of Edinburgh by an English army is the first action of the Rough Wooing.

The Burning of Edinburgh in 1544 by an English army was the first major action of the war of the Rough Wooing. The Provost of Edinburgh was compelled to allow the English to sack Leith and Edinburgh, and the city was burnt on 7 May. However, the Scottish artillery within Edinburgh Castle harassed the English forces, who had neither the time nor the resources to besiege the Castle. The English fleet sailed away loaded with captured goods, and with two ships that had belonged to King James V.
1625 Death and funeral of James VI and I

State funeral of James VI and I (1566–1625) is held at Westminster Abbey.

James VI and I (1566–1625), King of England, Scotland, and Ireland, died on 27 March 1625 at Theobalds, and was buried at Westminster Abbey on 7 May 1625.
1664 Louis_XIV

Inaugural celebrations begin at Louis XIV's new Palace of Versailles.

Louis XIV, known as the "Sun King", was King of France from 14 May 1643 until his death in 1715. He is the longest-reigning monarch in history, reigning for 72 years and 110 days. His reign brought about a golden age in French history, marked by a great expansion of the French colonial empire and a flourishing of French culture throughout Europe. As an absolute monarch, Louis expanded monarchical rule and diminished the power of the nobility, developing a strong centralised state ruled from the Palace of Versailles that persisted until the French Revolution.
1685

Battle of Vrtijeljka between rebels and Ottoman forces.

The Battle on Vrtijeljka (Serbian: бој на Вртијељци, romanized: boj na Vrtijeljci) was fought on the hill of Vrtijeljka near Cetinje between a Venetian irregular force and an advancing Ottoman force on 7 May 1685 at the start of the Morean War. The Venetian force was made up of fighters from the neighbouring areas, including the band of acclaimed hajduk Bajo Pivljanin, and several Christian tribes. The large Ottoman force was led by sanjak-bey Süleyman of Scutari.
1697 Stockholm

Stockholm's medieval castle Tre Kronor is destroyed by fire.

It is replaced in the 18th century by the current Royal Palace.
Stockholm is the capital and most populous city of Sweden, as well as the largest urban area in the Nordic countries. Approximately 1 million people live in the municipality, with 1.6 million in the urban area, and 2.5 million in the metropolitan area. The city stretches across fourteen islands where Lake Mälaren flows into the Baltic Sea. Outside the city to the east, and along the coast, is the island chain of the Stockholm archipelago. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by Swedish statesman Birger Jarl. The city serves as the county seat of Stockholm County.
1718 New_Orleans

The city of New Orleans is founded by Jean-Baptiste Le Moyne, Sieur de Bienville.

New Orleans is a consolidated city-parish located along the Mississippi River in the U.S. state of Louisiana. With a population of 383,997 at the 2020 census, New Orleans is the most populous city in Louisiana, the second-most populous in the Deep South, and the twelfth-most populous in the Southeastern United States; the New Orleans metropolitan area, with about 1 million residents, is the 59th-most populous metropolitan area in the United States. New Orleans serves as a major port and commercial hub for the broader Gulf Coast region. The city is coextensive with Orleans Parish.
1763 Pontiac's War

Pontiac's War begins with Pontiac's attempt to seize Fort Detroit from the British.

Pontiac's War (also known as Pontiac's Conspiracy or Pontiac's Rebellion) was launched in 1763 by a confederation of Native Americans who were dissatisfied with British rule in the Great Lakes region following the French and Indian War (1754–1763). Warriors from numerous nations joined in an effort to drive British soldiers and settlers out of the region. The war is named after Odawa leader Pontiac, the most prominent of many Indigenous leaders in the conflict. The war began in May 1763 when Native Americans, alarmed by policies imposed by British General Jeffery Amherst, attacked a number of British forts and settlements. Nine forts were destroyed, and hundreds of colonists were killed or captured, with many more fleeing the region. Hostilities came to an end after successful British Army expeditions in 1764 led to peace negotiations over the next two years. The Natives were unable to drive away the British, but the uprising prompted the British government to modify the policies that had provoked the conflict. Warfare on the North American frontier was brutal; the killing of prisoners, the targeting of civilians, and other atrocities were widespread. The ruthlessness of the conflict was a reflection of a growing racial divide between indigenous peoples and British colonists. The British government sought to prevent further racial violence by issuing the Royal Proclamation of 1763, which created a boundary between colonists and Natives.
1765 HMS_Victory

HMS Victory is launched at Chatham Dockyard, Kent.

She is not commissioned until 1778.
HMS Victory is a 104-gun first-rate wooden sailing ship of the line, best known for her role as Admiral Horatio Nelson's flagship during the Battle of Trafalgar in 1805. With 248 years of service as of 2026, she is the world's oldest naval vessel still in commission.
1775 Ottoman_Empire

The Ottoman Empire cedes Bukovina to the Habsburg monarchy.

The Ottoman Empire, also known historically as Turkey or the Turkish Empire, was a state that spanned much of Southeastern Europe, West Asia, and North Africa from the 14th century to the early 20th century, centred in modern-day Turkey. It also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries.
1794 French_Revolution

French Revolution: Robespierre introduces the Cult of the Supreme Being in the National Convention as the new state religion of the French First Republic.

The French Revolution was a period of political and societal change in France that began with the Estates General of 1789 and ended with the Coup of 18 Brumaire on 9 November 1799. Many of the revolution's ideas are considered fundamental principles of liberal democracy, and its values remain central to modern French political discourse. It was caused by a combination of social, political, and economic factors which the existing regime proved unable to manage.
1798 French_Revolutionary_Wars

French Revolutionary Wars: A French force attempting to dislodge a small British garrison on the Îles Saint-Marcouf is repulsed with heavy losses.

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.
1824 Ludwig van Beethoven

World premiere of Ludwig van Beethoven's Ninth Symphony in Vienna, Austria.

The performance is conducted by Michael Umlauf under the composer's supervision.
Ludwig van Beethoven (baptised 17 December 1770 – 26 March 1827) was a German composer, conductor, and pianist. Regarded as one of the greatest composers in the history of Western music, he was mentored during the Classical period, and his musical style was a key driver of the transition to Romantic music, and the expansion of instrumental forms such as the symphony, the piano sonata and the string quartet. His compositions have attracted extraordinary casual and scholarly interest, and remain among the most performed in the world. Born in Bonn, Beethoven was a musical prodigy. He was initially taught intensively by his father, Johann van Beethoven, and later by Christian Gottlob Neefe. He found relief from a dysfunctional home life with the family of Helene von Breuning, whose children he loved, befriended, and taught piano. At age 21, he moved to Vienna, which became his base, and studied composition with Joseph Haydn. Beethoven gained a reputation as a virtuoso pianist, and was soon patronized by Karl Alois, Prince Lichnowsky for compositions, which resulted in his three Piano Trios, Op. 1, the earliest works to which he accorded an opus number, in 1795. His Pathétique Sonata was composed in 1798. Around this time, Beethoven began experiencing symptoms of hearing loss. His career is divided into three periods. In the first, he composed in the classical style of Haydn and Wolfgang Amadeus Mozart. Beethoven's First Symphony premiered in 1800, and his first set of string quartets was published in 1801. The Moonlight Sonata, dedicated to his pupil Julie Guicciardi, is one of his most popular works. In the middle period (1802–1812), he developed a distinctive style. His Third (Eroica) and Fifth Symphonies premiered in 1805 and 1808, respectively. The former was unprecedented in scale and scope. His opera, Fidelio, premiered in 1805, and was later revised. His Violin Concerto appeared in 1806. His Razumovsky quartets were published in 1808. Other middle works include the Waldstein and Appassionata sonatas for piano, the Kreutzer sonata for violin and his Seventh Symphony. His Emperor piano concerto premiered in 1811, without the composer as soloist. His late period (1812–1827) included some of his most innovative works. His Missa solemnis and his final symphony, the Ninth, premiered in 1824. The latter was the first major example of a choral symphony. His Diabelli Variations and late piano sonatas, particularly the Hammerklavier, are summits of the keyboard literature. His late string quartets, including the Große Fuge, of 1825–1826, are considered pinnacles of the genre. After several months of illness, which left him bedridden, Beethoven died on 26 March 1827 at the age of 56.
1832

Greece's independence is recognized by the Treaty of London.

The London Conference of 1832 was an international conference convened to establish a stable government in Greece. Negotiations among the three Great Powers (Britain, France and Russia) resulted in the establishment of the Kingdom of Greece under a Bavarian prince. The decisions were ratified in the Treaty of Constantinople later that year. The treaty followed the Akkerman Convention which had previously recognized another territorial change in the Balkans, the suzerainty of the Principality of Serbia.
1840 Great Natchez Tornado

The Great Natchez Tornado strikes Natchez, Mississippi killing 317 people.

It is the second deadliest tornado in United States history.
The Great Natchez Tornado was a deadly tornado that hit Natchez, Mississippi, on Thursday, May 7, 1840. The tornado, while officially unrated, was the second-deadliest tornado in United States history; at least 317 people were killed and at least 109 were injured. Its 35-mile-long (56 km), 1,000-yard-wide (910 m; 3,000 ft; 0.57 mi; 0.91 km) path was marked by severe damage and uncertain estimates of casualties, though many enslaved Africans—possibly numbering in the hundreds—reportedly died on plantations in Louisiana. Tornado expert Thomas P. Grazulis retroactively rated the tornado F4 on the Fujita scale, while another report ranked it F5.
1864 American_Civil_War

American Civil War: The Army of the Potomac, under General Ulysses S.

Grant, breaks off from the Battle of the Wilderness and moves southwards.
The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States. The South saw slavery as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war ended with Union victory, the dissolution of the Confederacy and the abolition of slavery, freeing four million African Americans.
1864 Clipper

The world's oldest surviving clipper ship, the City of Adelaide is launched by William Pile, Hay and Co.

in Sunderland, England, for transporting passengers and goods between Britain and Australia.
A clipper was a type of mid-19th-century merchant sailing vessel, designed for speed. The term was also retrospectively applied to the Baltimore clipper, which originated in the late 18th century.
1895 Saint_Petersburg

In Saint Petersburg, Russian scientist Alexander Stepanovich Popov demonstrates to the Russian Physical and Chemical Society his invention, the Popov lightning detector—a primitive radio receiver.

In some parts of the former Soviet Union the anniversary of this day is celebrated as Radio Day.
Saint Petersburg, formerly known as Petrograd (Петроград), and later Leningrad (Ленинград), is the second-largest city in Russia, after Moscow, the nation's capital. Situated on the Neva River at the head of the Gulf of Finland on the Baltic Sea, its area of 1,439 square kilometers (556 sq mi) makes it the smallest administrative division of Russia by area. The city had a population of 5,601,911 residents as of 2021, with more than 6.4 million people living in the metropolitan area. Saint Petersburg is the fourth-most populous city in Europe, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As the former capital of the Russian Empire, and a historically strategic Baltic port, it is governed as a federal city.
1915 World_War_I

World War I: German submarine U-20 sinks RMS Lusitania, killing 1,199 people, including 128 Americans.

Public reaction to the sinking turns many former pro-Germans in the United States against the German Empire.
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

The Republic of China accedes to 13 of the 21 Demands, extending the Empire of Japan's control over Manchuria and the Chinese economy.

The Beiyang government was the internationally recognized government of the Republic of China between 1912 and 1928, based in Beijing. It was dominated by Yuan Shikai and the other generals of his Beiyang Army, hence the name.

1930

The 7.1 Mw Salmas earthquake shakes northwestern Iran and southeastern Turkey with a maximum Mercalli intensity of IX (Violent).

Up to three-thousand people were killed.
The 1930 Salmas earthquake occurred on 7 May at 01:34:26 IRST in West Azerbaijan province, Iran. The earthquake, which was among Iran's largest, measured 7.1 on the moment magnitude scale and had a maximum Mercalli intensity of IX (Violent). Prior to the earthquake a strong foreshock was felt fifteen hours earlier. Reports from seismologists and seismological organizations indicate that up to 3,000 fatalities may have occurred in northwest Iran and southeast Turkey. Sixty villages (including the large settlement of Dilman, which was relocated and rebuilt as Salmas) were destroyed in the Salmas Plain and in the surrounding mountainous regions. A sequence of aftershocks affected many villages, inflicting damage on some that had escaped devastation during the mainshock. An inspection of the region was undertaken, but not until decades later, at which time substantial surface faulting and other ground effects were documented.
1931 Francis Crowley

The stand-off between criminal Francis Crowley and 300 members of the New York Police Department takes place in his fifth-floor apartment on West 91st Street, New York City.

Francis "Two Gun" Crowley (October 31, 1912 – January 21, 1932) was an American murderer. His crime spree lasted nearly three months, ending in a two-hour shootout with the New York City Police Department on May 7, 1931 that was witnessed by 15,000 bystanders and received national attention.

1937 Spanish_Civil_War

Spanish Civil War: The German Condor Legion, equipped with Heinkel He 51 biplanes, arrives in Spain to assist Francisco Franco's forces.

The Spanish Civil War was fought in Spain from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans loyal to the left-leaning Popular Front government of the Second Spanish Republic included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists, who established the military-led Spanish State and were directly aided by an intervention from Fascist Italy and participation of Nazi Germany. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or communism and fascism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975.
1940 World_War_II

World War II: The Norway Debate in the British House of Commons begins, and leads to the replacement of Prime Minister Neville Chamberlain with Winston Churchill three days later.

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.
1942 Battle_of_the_Coral_Sea

World War II: During the Battle of the Coral Sea, United States Navy aircraft carrier aircraft attack and sink the Imperial Japanese Navy light aircraft carrier Shōhō; the battle marks the first time in naval history that two enemy fleets fight without visual contact between warring ships.

The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead. It was also the first military battle between aircraft carriers.
1945 U-boat

World War II: Last German U-boat attack of the war, two freighters are sunk off the Firth of Forth, Scotland.

U-boats are naval submarines operated by Germany, especially during World War I and World War II. The term is an anglicized form of the German word U-Boot, a shortening of Unterseeboot. Austro-Hungarian Navy submarines were also known as U-boats.

1948 Council_of_Europe

The Council of Europe is founded during the Hague Congress.

The Council of Europe is an international organisation which aims to uphold human rights, democracy and the rule of law in Europe. Founded in 1949, it is Europe's oldest intergovernmental organisation with the largest number of Member States, representing 46 European member states. The council is an official United Nations observer. The headquarters of the Council of Europe, as well as the European Court of Human Rights – one of its main bodies – are situated in Strasbourg, France. Field offices are spread in over 16 countries, including in Africa, namely Morocco and Tunisia. The Council uses English and French as its two official languages. The Committee of Ministers, the PACE, and the Congress of the Council of Europe also use German and Italian for some of their work. The council's two statutory bodies are the Committee of Ministers, which comprises the foreign ministers of each member state, and the Parliamentary Assembly of the Council of Europe (PACE), which is composed of members of the national parliaments of each member state.

1952 Integrated_circuit

The concept of the integrated circuit, the basis for all modern computers, is first published by Geoffrey Dummer.

An integrated circuit (IC), also known as a microchip or simply chip, is a compact assembly of electronic circuits formed from various electronic components, such as transistors, resistors, and capacitors, and their interconnections. These components are fabricated onto a thin, flat piece ("chip") of semiconductor material, most commonly silicon. Integrated circuits are integral to a wide variety of electronic devices performing functions such as data processing, control, and storage. They have transformed the field of electronics by enabling device miniaturization, improving performance, and reducing cost.
