HISTORY & TIMELINE
28 February

A journey through
28 February in history

From a gun that burst aboard an American warship in 1844 to a pope’s farewell in 2013, 28 February has seen new nations, new materials and the secret of life worked out in cardboard. This timeline follows the date across two centuries.

JUMP THROUGH TIME
IV
THE NINETEENTH CENTURY

The 1800s

Industry, empire, invention, reform and a century of enormous transformation.

Lönnrot signs the preface to the Kalevala

The country doctor Elias Lönnrot spent years collecting folk poems from singers in Finland and Karelia. He wove them into a single epic, the Kalevala, and signed its preface on 28 February 1835. The book gave Finns, then ruled by Russia, a national epic in their own language and fed a growing sense of identity. An expanded edition followed in 1849, and 28 February is celebrated in Finland as Kalevala Day, the day of Finnish culture.

A giant gun bursts aboard USS Princeton

On 28 February 1844, during a pleasure cruise on the Potomac for President John Tyler and hundreds of guests, the ‘Peacemaker’, then the largest gun in the US Navy, burst as it was fired. The Secretary of State, Abel Upshur, and the Navy Secretary, Thomas Gilmer, were among those killed. Tyler, who was below deck, was unhurt.

THE TWENTIETH CENTURY

The 1900s

War and peace, technological leaps, social change, politics, sport and popular culture.

Britain declares Egypt independent

On 28 February 1922, after three years of unrest that began with the revolution of 1919, Britain announced that its protectorate over Egypt was at an end and recognised the country as an independent sovereign state. The step was urged on London by the High Commissioner in Cairo, Lord Allenby. The independence was limited. Britain kept control of four ‘reserved’ matters: the security of imperial communications, Egypt’s defence, the protection of foreigners and minorities, and Sudan. The sultan, Fuad, took the title of king in March.

Nylon is made for the first time

On 28 February 1935 Wallace Carothers’s research team at DuPont’s Experimental Station in Wilmington, Delaware, produced a new polymer from adipic acid and hexamethylenediamine. Each ingredient has six carbon atoms, so it was known as fibre 66. Strong, elastic and silky, it became nylon, the first fully synthetic fibre made commercially. Nylon stockings went on sale in 1939 and 1940 and caused a sensation, before nylon was diverted to parachutes and other war work.

Unrest spreads across Taiwan: the 228 Incident

On the evening of 27 February 1947 officials of the government tobacco monopoly in Taipei seized a street seller’s cigarettes, and the confrontation turned violent. On 28 February protests against the Nationalist administration of Governor Chen Yi spread across the island. Once troops arrived from the mainland in March the uprising was put down with great force. Estimates of the dead range from about 10,000 to 30,000. The subject was forbidden for decades; Taiwan’s president apologised in 1995, and 28 February is now Peace Memorial Day.

Ex-servicemen are shot at Christiansborg crossroads

On 28 February 1948 unarmed African ex-servicemen marched in Accra, in the British Gold Coast, to petition the governor at Christiansborg Castle about unpaid war benefits. Police opened fire at the crossroads, killing three of them, and riots followed in the city. The shootings hastened the colony’s path to independence as Ghana in 1957.

Crick and Watson crack the structure of DNA

On 28 February 1953, shuffling cardboard models of DNA’s four bases in the Cavendish Laboratory in Cambridge, James Watson saw that the pairs A-T and C-G have the same shape and could form the rungs of a twisted ladder. With Francis Crick he quickly built the double helix. Watson later recalled Crick telling lunchtime drinkers at the Eagle pub that they had found the secret of life. Their model rested on X-ray evidence from Rosalind Franklin and Maurice Wilkins at King’s College London. It was published in Nature in April 1953, and Watson, Crick and Wilkins shared the Nobel Prize in 1962, after Franklin’s death.

The Moorgate Tube crash

At 8.46 on the morning of 28 February 1975 a London Underground train failed to stop at Moorgate station and ran into the end wall of a dead-end tunnel. Forty-three people died, the worst peacetime accident on the Underground. The cause was never established; afterwards systems were fitted to stop trains automatically at such terminal platforms.

Record audience says goodbye to M*A*S*H

After eleven seasons, the American comedy-drama M*A*S*H, set in an army field hospital during the Korean War, ended on 28 February 1983 with a two-and-a-half-hour episode, ‘Goodbye, Farewell and Amen’. An average of almost 106 million Americans watched on CBS. It is still the most-watched episode of any scripted series in American television history.

Sweden’s prime minister is shot in Stockholm

Late on the evening of 28 February 1986, Olof Palme was walking home from a cinema on Sveavägen in central Stockholm with his wife, Lisbeth, and no bodyguards. A gunman shot him in the back and wounded Lisbeth. Palme was declared dead in hospital shortly after midnight. It was the first killing of a Swedish head of government since King Gustav III in 1792. One man was convicted and then acquitted on appeal; in 2020 prosecutors named another suspect, who had died in 2000, and closed the case.

A pope steps down

At eight o’clock in the evening on 28 February 2013 the resignation of Pope Benedict XVI took effect and the See of Rome fell vacant. He had announced his decision on 11 February, saying that his strength of mind and body was no longer adequate to the office. He was the first pope to resign in nearly 600 years, since Gregory XII in 1415. Benedict spent his last hours as pope at Castel Gandolfo; on 13 March the cardinals elected his successor, Francis.
