1964

Tanganyika and Zanzibar become one republic

On 26 April 1964 the mainland republic of Tanganyika and the islands of Zanzibar joined to form a single state. Julius Nyerere and Abeid Amani Karume had signed the Articles of Union four days earlier, and at the Karimjee Hall in Dar es Salaam they exchanged the documents and mixed soil from both lands to mark the union.

Nyerere became president and Karume first vice-president, while Zanzibar kept its own government for island affairs. Later that year the new country took the name Tanzania, and 26 April is still a national holiday, Union Day.

1478

The Pazzi conspirators strike in Florence Cathedral

On 26 April 1478, during Sunday Mass in Florence Cathedral, men in the pay of the rival Pazzi family attacked the brothers Lorenzo and Giuliano de’ Medici, who ruled the city in all but name. Giuliano was stabbed to death, but Lorenzo, wounded in the neck, escaped into the sacristy and barred the door.

The plot had the backing of Pope Sixtus IV’s circle and the archbishop of Pisa, Francesco Salviati, yet Florence rallied to the Medici. Salviati and dozens of conspirators were executed within days, some hanged from the windows of the government palace, and Lorenzo’s power emerged stronger than before.

1986

A reactor explodes at Chernobyl

At 1.23 in the morning on 26 April 1986, during a safety test at low power, reactor number 4 at the Chernobyl nuclear power station in Soviet Ukraine went out of control. Two explosions destroyed the core and the roof of the building, and a fire released large amounts of radioactive material into the air.

Two workers died that night and 28 more, mostly firefighters and plant staff, died of radiation sickness within months. About 116,000 people were evacuated in 1986, including the town of Pripyat, and a wide exclusion zone around the plant remains today.

1956

The Ideal X carries the first boxes to sea

On 26 April 1956 the converted tanker Ideal X sailed from Port Newark, New Jersey, for Houston, Texas, with 58 metal containers loaded on a deck built for the purpose. The idea came from Malcom McLean, a trucking businessman who wanted to lift whole trailer boxes on and off ships instead of handling cargo piece by piece.

The containers were loaded in under eight hours and the ship reached Houston five days later. Standard shipping containers went on to transform world trade, cutting the cost of moving goods and reshaping the world’s ports.

1803

Stones fall from the sky at L’Aigle

On 26 April 1803 a shower of more than 3,000 stones fell around the small Normandy town of L’Aigle, watched by many startled villagers. At the time most European scientists doubted that rocks could fall from the sky and put such stories down to superstition.

The French Academy of Sciences sent the young physicist Jean-Baptiste Biot to investigate. His careful report, combining the stones themselves with the evidence of many witnesses, convinced the scientific world that meteorites were real and founded the science of meteoritics.

1903

Atlético Madrid is founded

On 26 April 1903 a group of Basque students living in Madrid founded a football club as a local branch of Athletic Club of Bilbao. They had been inspired by Athletic’s comeback win in the Spanish cup final earlier that month.

The club soon went its own way, and after several changes of name it became Club Atlético de Madrid in 1947. It has since won the Spanish league many times and reached three European Cup and Champions League finals.

Petrarch climbs Mont Ventoux for the view

On 26 April 1336, by his own account, the Italian poet Petrarch climbed Mont Ventoux in Provence with his brother and two servants, simply to see the view from the top. He described the ascent in a famous letter to his former confessor, later collected among his Familiar Letters.

At the summit he opened his copy of Saint Augustine’s Confessions and read a passage rebuking people who marvel at mountains but neglect their own souls. Scholars doubt some details of the letter, which may have been written years later, but it is often seen as an early sign of the Renaissance outlook.

Annual

World Intellectual Property Day

World Intellectual Property Day was created by the member states of the World Intellectual Property Organization in 2000 and first held in 2001. It falls on 26 April because the convention founding the organisation came into force on that day in 1970, and it highlights the part that patents, copyright and trademarks play in encouraging invention and creativity.
