A journey through
1 March in history

From the founding of Rio de Janeiro in 1565 to Bosnia’s vote for independence in 1992, 1 March has seen cities founded, empires humbled and the most powerful American bomb ever tested. This timeline follows the date across more than four centuries.

The Portuguese found Rio de Janeiro

On 1 March 1565 the Portuguese commander Estácio de Sá landed at the entrance to Guanabara Bay and founded the settlement of São Sebastião do Rio de Janeiro, named after King Sebastião of Portugal and his patron saint. The Jesuits Manuel da Nóbrega and José de Anchieta were with him. The aim was to drive out the French, who had built a colony in the bay a decade earlier. Estácio de Sá was mortally wounded by an arrow in the fighting, but the city survived and grew into one of the great cities of the Americas.

Yellowstone becomes the first national park

On 1 March 1872 President Ulysses S. Grant signed the act that set aside more than two million acres of geysers, canyons and forest in the Wyoming and Montana territories ‘as a public park or pleasuring-ground for the benefit and enjoyment of the people’. Yellowstone was the first national park in the United States and in the world. The idea spread, and today there are thousands of national parks in countries across the globe.

Ethiopia defeats Italy at Adwa

On 1 March 1896, in the mountains near Adwa in northern Ethiopia, the army of Emperor Menelik II crushed an Italian invasion force of about 20,000 under General Oreste Baratieri. Menelik’s troops, many armed with modern rifles bought from France and Russia, greatly outnumbered the Italians, who had marched through the night on separate columns. The defeat ended Italy’s first war against Ethiopia and forced it to recognise the country’s independence. Adwa became a symbol across Africa and beyond: an African state had beaten a European colonial army and kept its freedom.

Becquerel stumbles on radioactivity

Henri Becquerel thought that uranium salts might give off X-rays after being exposed to sunlight. When cloudy Paris weather stopped his experiment in late February 1896, he put the salts and some wrapped photographic plates away in a drawer. On 1 March he developed the plates anyway and found them strongly fogged: the uranium was giving off rays with no help from the Sun. It was the discovery of radioactivity. Becquerel shared the 1903 Nobel Prize in Physics with Marie and Pierre Curie, who went on to find new radioactive elements.

THE TWENTIETH CENTURY

The 1900s

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

Korea’s March First Movement

On 1 March 1919 a Declaration of Independence signed by 33 religious leaders was read out in Pagoda Park in Seoul, and crowds poured into the streets shouting ‘Mansei!’, long live Korean independence. Korea had been ruled by Japan since 1910. Over the following year some two million people joined more than 1,500 peaceful demonstrations. Japanese forces killed about 7,000 and wounded many more. The rising failed to free Korea, but it led to a provisional government in exile in Shanghai, and 1 March is a national holiday in South Korea.

The government takes over the finished Hoover Dam

With all its features complete, the Hoover Dam on the Colorado River was formally accepted from its builders, the Six Companies consortium, by Interior Secretary Harold Ickes on 1 March 1936, more than two years ahead of schedule. It tamed the river’s floods and supplied water and power to the growing American south-west.

Bulgaria joins the Axis

In Vienna on 1 March 1941 Bulgaria’s prime minister, Bogdan Filov, signed the Tripartite Pact, joining Germany, Italy and Japan. King Boris III allowed German troops to cross the country to attack Greece, hoping to win back land Bulgaria had lost in earlier wars.

The Castle Bravo test poisons the Pacific

On 1 March 1954 the United States exploded a hydrogen bomb on Bikini Atoll in the Marshall Islands. Scientists expected about 5 megatons; the blast was about 15, a thousand times the power of the Hiroshima bomb and the largest American test ever. Radioactive fallout spread over thousands of square miles, contaminating Marshall Islanders, American servicemen and the crew of the Japanese fishing boat Lucky Dragon. The disaster fed worldwide alarm about testing that led to the treaty banning tests in the atmosphere in 1963.

Kennedy creates the Peace Corps

Less than six weeks after taking office, President John F. Kennedy signed an executive order on 1 March 1961 setting up the Peace Corps, which sends American volunteers to work in schools, health and farming projects abroad. Congress made it permanent that September, by which time the first volunteers were already at work abroad.

Venera 3 reaches Venus

The Soviet probe Venera 3, launched in November 1965, struck the surface of Venus on 1 March 1966. It was the first spacecraft to reach another planet. Its radio had failed two weeks earlier, so it sent back no information about Venus. But it carried medallions bearing the Soviet coat of arms, and the Soviet Union celebrated the landing as a first.

Bobby Sands begins his hunger strike

On 1 March 1981 Bobby Sands, leader of the IRA prisoners in the Maze prison near Belfast, refused food in a protest demanding to be treated as a political prisoner. While on strike he was elected to Parliament. He died on 5 May after 66 days, and nine more men died before the strike ended in October.

Bosnia and Herzegovina votes for independence

Voting in Bosnia and Herzegovina’s independence referendum closed on 1 March 1992. Of the 64 per cent who took part, 99.7 per cent chose independence from Yugoslavia, but most Bosnian Serbs boycotted the vote. Independence was proclaimed on 3 March and recognised by the European Community and the United States in April, as war engulfed the country.
