January 20 in History

Pope Fabian (Latin: Fabianus) was the bishop of Rome and head of the Catholic Church from 10 January 236 until his death on 20 January 250, succeeding Anterus. A dove is said to have descended on his head to mark him as the Holy Spirit's unexpected choice to become the next pope. He was succeeded by Cornelius. Most of his papacy was characterized by amicable relations with the imperial government, and the schism between the Roman congregations of Pontian and Hippolytus was ended. He divided Rome into diaconates and appointed secretaries to collect the records of the martyrs. He sent out seven "apostles to the Gauls" as missionaries, but probably did not baptize Emperor Philip the Arab as is alleged. He died a martyr at the beginning of the Decian persecution and is venerated as a saint by the Catholic Church and the Orthodox Church.

Lalli (Finnish: [ˈlɑlːi]) is an apocryphal character from Finnish history and one of the most well-known figures in Finnish medieval legend. According to tradition, he was a prosperous yeoman farmer who killed Bishop Henry, who was spreading Christianity to then pagan Finland, on the ice of lake Köyliö on 20 January in the late 1150s. In medieval church art, Lalli became a central attribute in the iconography of Saint Henry, typically depicted being trampled underfoot by the bishop as a symbol of his sanctity. In the 19th and early 20th centuries, a fennomanist reinterpretation cast him as a symbol of Finnish resistance against Swedish dominance, and in some circles even as a folk hero.

Simon de Montfort's Parliament was an English parliament held from 20 January 1265 until mid-March of the same year, called by Simon de Montfort, a baronial rebel leader. Montfort had seized power in England following his victory over Henry III at the Battle of Lewes during the Second Barons' War, but his grip on the country was under threat. To gain more support, he summoned not only the barons and the knights of the shires, as in previous parliaments, but also burgesses from the major towns. They discussed radical reforms and temporarily stabilised Montfort's political situation. Montfort was killed at the Battle of Evesham later that year, but the idea of inviting both knights and burgesses to parliaments became more popular under Henry's son Edward I. By the 14th century, it had become the norm, with the gathering becoming known as the House of Commons.

Władysław I Łokietek, in English known as the "Elbow-high" or Ladislaus the Short (c. 1260/1261 – 2 March 1333), was King of Poland from 1320 to 1333, and duke of several of the provinces and principalities in the preceding years. He was a member of the royal Piast dynasty, the son of Duke Casimir I of Kuyavia, and great-grandson of High-Duke Casimir II the Just. Władysław I inherited a small portion of his father's domain, but his dominion grew as some of his brothers died young. He unsuccessfully tried to incorporate the Duchy of Kraków (the Seniorate Province) in 1289, following the death of his half-brother Leszek II the Black and the withdrawal from contention of his ally Bolesław II of Masovia. After a period in exile during the rule of Wenceslaus II, Władysław regained several duchies and then Kraków in 1306 when Wenceslaus III of Bohemia was murdered. He temporarily took control of part of Greater Poland after the death of his ally Przemysł II, lost it, and then regained it. Władysław was a skilled military leader, but also an administrator; he conquered Gdańsk Pomerania, and left it to familial governors. For the defense of this territory, he turned to the Teutonic Knights, who then demanded an exorbitant sum, or the land itself as an alternative. This led to an extended conflict with the Knights. Perhaps his greatest achievement was gaining papal permission to be crowned king of Poland in 1320, which occurred for the first time at Wawel Cathedral in Kraków. Władysław died in 1333 and was succeeded by his son, Casimir III the Great.

Edward Balliol or Edward de Balliol (Scottish Gaelic: Èideard Balliol; c. 1283 – January 1364) was a claimant to the Scottish throne during the Second War of Scottish Independence. With English help, he ruled parts of the kingdom from 1332 to 1356.

The Taula de canvi of Barcelona, created in 1401 and still extant in diminished form in the 19th century, was a municipal bank in Barcelona that has been described as the first-ever central bank. A Taula de canvi (literally "table of exchange" in Catalan), also Taula de cambi or simply Taula, was a type of municipal public bank that existed in the Crown of Aragon in the late Middle Ages and early modern period.

Christian II (1 July 1481 – 25 January 1559) was a monarch under the Kalmar Union, reigning as King of Denmark and Norway from 1513 until 1523. He was briefly King of Sweden from 1520 until 1521. As king of Denmark, he was concurrently Duke of Schleswig and Holstein in joint rule with his uncle Frederick. As king, Christian tried to maintain the Kalmar Union between the Scandinavian countries, which brought him to war with Sweden, lasting between 1518 and 1523. Though he captured the country in 1520, the subsequent slaughter of leading Swedish nobility, churchmen, and others, known as the Stockholm Bloodbath, caused the Swedes to rise against his rule. He was deposed in a rebellion led by the nobleman and later king of Sweden, Gustav Vasa. He attempted to bring in a radical reform of the Danish state in 1521–22, which would have strengthened the rights of commoners at the expense of the nobles and clergy. The nobility rose against him in 1523, and he was exiled to the Netherlands, ceding the Danish throne to his uncle Frederick. After attempting to reclaim the thrones in 1531, he was arrested and held in captivity for the rest of his life, first in Sønderborg Castle and later at Kalundborg Castle. Supporters tried to restore him to power both during his exile and his imprisonment but they were defeated decisively during the Count's Feud in 1536. Christian died at Kalundborg in 1559. In 1515, Christian married Isabella of Austria, granddaughter of Maximilian I, Holy Roman Emperor. Isabella died in 1526, after which her family took Christian's three children from him. His relationship with his mistress, Dyveke Sigbritsdatter, pre-dated his marriage and continued until her death in 1517. Christian's persecution of her supposed murderer contributed to his political isolation and downfall. Dyveke's mother, Sigbrit Willoms, became an influential councillor and followed Christian into exile.

The Battle of Rio de Janeiro or the Battle of Guanabara Bay took place on 20 January 1567 at Rio de Janeiro that ended with the definitive defeat of the French. Specifically, the battle was an attack on the fortification of Uruçú-mirim. The Portuguese commander, Estácio de Sá, was hit by an arrow which perforated his eye, and died on 20 February.

León, officially León de Los Aldama, is the most populous city and municipal seat of the municipality of León in the Mexican state of Guanajuato. In the 2020 census, INEGI reported 1,579,803 people living in the city of León and 1,721,215 in the municipality, making it the fourth-most populous city and third-most populous municipality in Mexico. The metropolitan area of León recorded a population of 2,140,094 in the 2020 state census, making it the seventh most populous metropolitan area in Mexico. León is part of the macroregion of the Bajío within the Mexican Plateau, located roughly in the center of the country.

The trial of Charles I took place in January 1649, marking the first time a reigning monarch was tried and executed by his own subjects. Following years of conflict during the English Civil War, which pitted the Royalists loyal to Charles I against the Parliamentarians seeking to limit his powers, the king was captured by Parliamentary forces in 1646. In November 1648, after a series of failed negotiations and increasing tensions, the Rump Parliament established the High Court of Justice to try Charles for treason. The court was presided over by John Bradshaw, and the proceedings were marked by controversy and legal disputes, as many questioned the legitimacy of trying a king. The charges against Charles included high treason, specifically waging war against the realm and betraying the trust of the people. In accordance with his belief that he ruled by divine right and could not be subjected to the authority of Parliament, Charles maintained a defiant stance throughout the trial, refusing to recognise the court's legitimacy. He was ultimately found guilty and sentenced to death. On 30 January 1649 Charles I was executed outside the Banqueting House in Whitehall, London. His execution sent shockwaves across Europe and heralded a new era in English governance, leading to the establishment of the Commonwealth under Oliver Cromwell. The trial and execution of Charles I remain pivotal events that challenged the traditional notions of monarchy and laid the groundwork for the modern British constitutional system.

Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the Cello Suites and Sonatas and Partitas for Solo Violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St. Matthew Passion and the Mass in B minor. He is known for his mastery of counterpoint, as heard in The Musical Offering and The Art of Fugue. Felix Mendelssohn precipitated the Bach Revival with a performance of the St. Matthew Passion in 1829. Ever since, Bach has been acclaimed as one of the greatest composers in the history of Western music.

Great Britain, officially the Kingdom of Great Britain, was a sovereign state in Western Europe from 1707 to the end of 1800. The state was created by the 1706 Treaty of Union and ratified by the Acts of Union 1707, which united the Kingdom of England and the Kingdom of Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands, with the exception of the Isle of Man and the Channel Islands. The unitary state was governed by a single parliament at the Palace of Westminster, but the distinct legal systems—English law and Scots law—remained in use, as did distinct educational systems and religious institutions, namely the Church of England and the Church of Scotland remaining as the national churches of England and Scotland respectively.

The Rattanakosin Kingdom, also known as the Kingdom of Siam after 1855, refers to the Siamese kingdom between 1782 and 1932. It was founded in 1782 with the establishment of Rattanakosin (Bangkok), which replaced the city of Thonburi as the capital of Siam.

The First Fleet were eleven British ships which transported a group of settlers to mainland Australia, marking the beginning of the British colonisation of Australia. It consisted of two Royal Navy vessels, three storeships and six convict transports under the command of Captain Arthur Phillip. On 13 May 1787, the ships, with over 1,400 convicts, marines, sailors, colonial officials, and free settlers onboard, left Portsmouth and travelled over 24,000 kilometres and over 250 days before arriving in Botany Bay, New South Wales, on 18 January 1788. Governor Arthur Phillip rejected Botany Bay, choosing instead Port Jackson to the north as the site for the new colony; the Fleet arrived there on 26 January 1788. The Fleet established the Colony of New South Wales as a penal colony; the first British settlement in Australia.

The Battle of Yungay (or Yungai) was the final battle of the War of the Confederation, fought on January 20, 1839, near Yungay, Peru. The United Restoration Army, led by Chilean General Manuel Bulnes, consisting mainly of Chileans and 600 North Peruvian dissidents, attacked the Peru-Bolivian Confederation forces led by Andrés de Santa Cruz in northern Peru, 200 kilometers (120 mi) north of Lima. After six hours of fighting, the Restorers destroyed the Confederate Army, bringing the War of the Confederation to its end. Santa Cruz exiled himself in Guayaquil, Ecuador. The new Peruvian government paid its debt with Chile from the liberation expedition from a decade ago, and gave awards to Chilean and Peruvian officials. Peruvian officers who served under the Confederation, including Guillermo Miller, Mariano Necochea, Luis José Orbegoso, and Domingo Nieto, were banned from the Peruvian Army.

The Pangkor Treaty of 1874 was a treaty signed between Great Britain and the Sultan of Perak on 20 January 1874, on the Colonial Steamer Pluto, off the coast of Perak. The treaty is significant in the history of the Malay states as it legitimised British control of the Malay rulers and paved the way for British imperialism in Malaya. It was the result of a multi-day conference organised by Andrew Clarke, the Governor of the Straits Settlements, to solve two problems: the Larut War and the disputed succession of the sultanship of Perak.

The 1876–77 Constantinople Conference (Turkish: Tersane Konferansı "Shipyard Conference", after the venue Tersane Sarayı "Shipyard Palace") of the Great Powers (Austria-Hungary, Britain, France, Germany, Italy and Russia) was held in Constantinople (now Istanbul) from 23 December 1876 until 20 January 1877. Following the beginning of the Herzegovinian Uprising in 1875 and the April Uprising in April 1876, the Great Powers agreed on a project for political reforms in Bosnia and in the Ottoman territories with a majority-Bulgarian population. The Ottoman Empire refused the proposed reforms, leading to the Russo-Turkish War a few months later.

The first constitution of the modern Turkish state, it was ratified by the Grand National Assembly of Turkey in January 1921. It was a simple document consisting of only 23 short articles. In October 1923 the constitution was amended to declare Turkey to be a republic. In April the following year the constitution was replaced by an entirely new document, the Constitution of 1924.

The Irish Civil War (Irish: Cogadh Cathartha na hÉireann; 28 June 1922 – 24 May 1923) was a conflict that followed the Irish War of Independence and accompanied the establishment of the Irish Free State, an entity independent from the United Kingdom but within the British Empire. The civil war was waged between the Provisional Government of Ireland and the Anti-Treaty IRA over the Anglo-Irish Treaty. The Provisional Government (which became the Free State in December 1922) supported the terms of the treaty, while the anti-Treaty opposition saw it as a betrayal of the Irish Republic proclaimed during the Easter Rising of 1916. Many of the combatants had fought together against the British in the Irish Republican Army during the War of Independence and had divided after that conflict ended and the treaty negotiations began. The Civil War was won by the pro-treaty National Army, who first secured Dublin by early July, then went on the offensive against the anti-Treaty strongholds of the south and west, especially the 'Munster Republic'. All urban centres had been captured by the National Army by late August. The guerrilla phase of the Irish Civil War lasted another 10 months, before the IRA leadership issued a "dump arms" order to all units, effectively ending the conflict. The National Army benefited from substantial quantities of weapons provided by the British government, particularly artillery and armoured cars. The conflict left Irish society divided and embittered for generations. Today, the three largest political parties in Ireland are direct descendants of the opposing sides in the war: Fine Gael, from the supporters of the pro-Treaty side; Fianna Fáil, the party formed from the bulk of the anti-Treaty republicans by Éamon de Valera; and Sinn Féin, comprising the minority of anti-Treaty republicans who refused to join any partitionist party.

The city has an area of 239 km2 (92 sq mi), while the metropolitan area covers 1,803 km2 (696 sq mi). The city proper is administratively known as the "Municipality of Bucharest", and has the same administrative level as that of a national county, being further subdivided into six sectors, each governed by a local mayor. Bucharest is a major cultural, political and economic hub, the country's seat of government, and the capital of the Muntenia region. It is an enclave completely surrounded by Ilfov County.

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.

Nazi Germany, officially the German Reich and later the Greater German Reich, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", was the Nazi claim that Nazi Germany was the successor to the Holy Roman Empire (800–1806) and the German Empire (1871–1918); the Nazis called it the Thousand-Year Reich, but it ended just 12 years later in May 1945, when the Allies defeated Germany and entered Berlin, ending World War II in Europe.

Pakistan is one of nine states that possess nuclear weapons. Pakistan is not party to the Nuclear Non-Proliferation Treaty. Pakistan's arsenal is estimated at 170 nuclear weapons as of 2025. Pakistan carried out two nuclear tests, Chagai-I and Chagai-II, both in 1998 and underground. Pakistan's nuclear weapons programme began in 1972 under Prime Minister Zulfikar Ali Bhutto following Pakistan's defeat in the Indo-Pakistani War of 1971 and India's advancing nuclear programme. The programme was developed through a combination of domestic scientific research, clandestine procurement networks associated with Abdul Qadeer Khan, as well as external political and financial support. During its early development, the government sought political and financial backing from several Muslim-majority countries and Arab states in the MENA region. Scholars identify Saudi Arabia as providing prolonged financial assistance that helped sustain the programme during periods of economic pressure and international sanctions, while Libya under then dictator Muammar Qaddafi is described as having provided both financial and material support during the programme's formative period. Pakistan's nuclear weapons doctrine, full spectrum deterrence, officially rejects no first use, promising to use "any weapon in its arsenal" to protect its national interests in the event of an attack. Pakistan's primary strategic concern is potential conflict with India, which also possesses nuclear weapons. Pakistan operates approximately 126 land-based missiles, primarily ballistic, of various short, medium, and intermediate ranges. Approximately 36 bombs and Ra'ad I/Ra'ad-II cruise missiles are assigned to Mirage III and Mirage 5 fighter aircraft. The Babur-III submarine-launched cruise missile is under development. Pakistan may possess smaller boosted fission weapons, but is not believed to have tested thermonuclear weapons. Since 2001, US officials have prioritised safeguarding Pakistan's nuclear arsenal from potential nuclear terrorism, supplying equipment and training, and drafting military contingency plans. Pakistan is not widely suspected of either producing biological weapons or having an offensive biological programme. Pakistan is a party to the Geneva Protocol, Chemical Weapons Convention, as well as the Biological Weapons Convention.

Amílcar Lopes Cabral (Portuguese: [ɐˈmilkaɾ ˈlɔpɨʃ kɐˈbɾal]; (1924-09-12)12 September 1924 – (1973-01-20)20 January 1973) was a Bissau-Guinean and Cape Verdean agricultural engineer, political organizer, diplomat, and half-brother of Luís Cabral.

The Syrian civil war was an armed conflict that began with the Syrian revolution in March 2011, when popular discontent with the Ba'athist regime ruled by Bashar al-Assad triggered large-scale protests and pro-democracy rallies across Syria, as part of the wider Arab Spring. The Assad regime responded to the protests with lethal force, which led to a series of defections, the emergence of armed opposition groups, and the civilian uprising descending into a civil 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.
