23 April in history

This timeline follows the date across more than twenty-two centuries.

Rome dedicates a temple to Venus of Eryx

On 23 April 215 BC, by the date the Romans kept as its founding day, a temple to Venus Erycina was dedicated on the Capitoline Hill in Rome. Quintus Fabius Maximus had vowed it after the crushing defeat by Hannibal at Lake Trasimene two years earlier, on the advice of the Sibylline Books. The goddess was brought from Eryx in Sicily, a sign of Rome’s search for divine help in its war with Carthage. The day was also the Vinalia, a wine festival held at the temple.

Brian Boru’s army fights at Clontarf

On 23 April 1014, Good Friday, the forces of Brian Boru, High King of Ireland, met an alliance of the Norse king of Dublin, the king of Leinster and Viking fighters from Orkney and the Isle of Man on the shore at Clontarf, north of Dublin. The fighting lasted most of the day and the losses on both sides were unusually heavy. Brian’s side held the field, but the elderly king was killed in his tent by a retreating Norseman, and his son and grandson also died. Later tradition turned the battle into a national victory over the Vikings, although historians now see it as much a struggle among Irish kingdoms, with Irish and Norse fighting on both sides.

Estonians rise on St George’s Night

On the night of 23 April 1343 (Julian calendar), Estonians in the province of Harju rose against the Danish crown and the German landowners who had ruled them since the crusades of the 13th century. Manors were burnt, the abbey at Padise was attacked and an army soon besieged Tallinn. The rising was put down with the help of the Teutonic Order, and in 1346 Denmark sold its Estonian lands to the order. It later became a symbol of resistance in Estonian national memory.

Bavaria’s beer purity law is issued at Ingolstadt

On 23 April 1516 Duke Wilhelm IV of Bavaria issued an ordinance at Ingolstadt, before an assembly of nobles and knights, laying down that beer across the duchy could be brewed only from barley, hops and water. Yeast was not named because its role in brewing was not yet understood. The rules also fixed the price of beer through the year and threatened to confiscate any beer brewed against them. Keeping wheat and rye out of the brewhouse helped protect bakers’ supplies of bread grain. The ordinance later became known as the Reinheitsgebot, and German brewers still cite it five centuries on.

The comuneros are defeated at Villalar

On 23 April 1521 royal cavalry routed the army of the comuneros, the Castilian towns in revolt against the young King Charles I, near Villalar in the province of Valladolid. Their leaders Juan de Padilla, Juan Bravo and Francisco Maldonado were captured and beheaded the next day. The defeat ended the main armed resistance to Charles, who was also Holy Roman Emperor as Charles V. The region of Castile and León now marks the date as its official day.

A new Turkish parliament opens in Ankara

On 23 April 1920 the Grand National Assembly met for the first time in a modest building in Ankara. Allied forces had occupied Istanbul the month before and the Ottoman parliament had been closed, so deputies who escaped arrest joined representatives of the Anatolian resistance to form a new assembly. The next day it elected Mustafa Kemal as its president. The assembly directed the war of independence, rejected the Treaty of Sèvres and in 1923 proclaimed the Republic of Turkey. Turkey marks the date each year as National Sovereignty and Children’s Day.

Cardiff City take the FA Cup out of England

On 23 April 1927 Cardiff City beat Arsenal 1-0 in the FA Cup final at Wembley, watched by more than 91,000 people. The only goal came in the 75th minute, when a low shot from Hughie Ferguson slipped from the grasp of Arsenal’s goalkeeper, Dan Lewis, and rolled over the line. It remains the only time the cup has been won by a club from outside England. Lewis blamed his new, shiny jersey, and Arsenal are said to have washed new goalkeeping shirts before use ever since.

The Philippines elects Manuel Roxas

On 23 April 1946 voters in the Philippines, still recovering from the Japanese occupation, chose Manuel Roxas of the new Liberal Party as president. He beat the sitting president, Sergio Osmeña, with about 54 per cent of the vote. Roxas was the last president of the Commonwealth of the Philippines under American rule. When the country became fully independent on 4 July 1946 he became the first president of the new republic.

Soyuz 1 carries Vladimir Komarov into orbit

On 23 April 1967 Vladimir Komarov was launched from Baikonur, in what is now Kazakhstan, on the first crewed flight of the Soviet Union’s new Soyuz spacecraft. Almost at once one of its two solar panels failed to open, cutting the craft’s power and upsetting the sensors it needed to steer. A planned second launch to meet him was cancelled and he was brought home early. During the descent on 24 April the main parachute failed and Komarov was killed, the first person to die during a space flight. Soyuz was redesigned and remains in service.

Namibia takes its seat at the United Nations

On 23 April 1990 Namibia was admitted as the 160th member of the United Nations, a month after its independence from South African rule. The UN had long claimed responsibility for the territory, then called South West Africa, and a UN mission, UNTAG, had overseen the elections that led to independence. The Security Council had recommended admission on 17 April. Namibia joined the Commonwealth in the same period.

Eritreans begin voting on independence

On 23 April 1993 polling opened in Eritrea’s referendum on independence from Ethiopia, and voting continued until 25 April. It followed three decades of armed struggle that ended when the Eritrean People’s Liberation Front took Asmara in 1991. About 98 per cent of registered voters took part, and 99.8 per cent of them chose independence. A United Nations observer mission, UNOVER, joined observers from the Organization of African Unity and others in judging the vote free and fair. Eritrea declared independence the following month.

The first video goes up on YouTube

On 23 April 2005 Jawed Karim, one of the three founders of YouTube, uploaded a 19-second clip called ‘Me at the zoo’. Filmed by a school friend at San Diego Zoo, it shows him in front of the elephants remarking on their long trunks. The site was still weeks from its public launch. Within two decades YouTube had become one of the most visited websites in the world, and the unremarkable clip, still online, has been watched hundreds of millions of times.
