The great San Francisco earthquake

Just after five in the morning on 18 April 1906, the San Andreas fault slipped along almost 300 miles of northern California. The shaking lasted under a minute, but broken gas mains and toppled chimneys started fires that burned across San Francisco for days.

At least 3,000 people died and more than half the city’s population lost their homes. Studying the torn ground afterwards, geologists developed the idea of elastic rebound, which still underpins how scientists explain earthquakes.

Asia and Africa meet at Bandung

On 18 April 1955, delegates from 29 Asian and African countries gathered in the Indonesian hill city of Bandung, opened by President Sukarno. Between them they spoke for more than half of the world’s people, many of whom had only recently thrown off colonial rule.

Over a week, leaders such as Nehru, Zhou Enlai and Nasser discussed decolonisation, development and how to stay out of the Cold War’s two camps. Their final declaration helped lay the ground for the Non-Aligned Movement.

Zimbabwe becomes independent

At midnight on 18 April 1980, the British flag was lowered at Rufaro Stadium in Salisbury and the flag of Zimbabwe raised in its place. After decades of white-minority rule and a long liberation war, the former Southern Rhodesia became a sovereign state.

Robert Mugabe, whose party had won the elections weeks earlier, became prime minister, with Canaan Banana as president. Bob Marley played at the celebrations, and 18 April remains the country’s national holiday.

Luther refuses to recant at Worms

Summoned before Emperor Charles V at the Diet of Worms, Martin Luther had asked for a day to think when told to disown his books. On 18 April 1521 he gave his answer: unless shown wrong by Scripture or plain reason, he would take nothing back, because his conscience was bound to the Word of God.

The famous line ‘Here I stand, I can do no other’ was probably added to the story later. A month on, the emperor declared Luther an outlaw, but his stand made the split in Western Christianity all but certain.

London’s ‘cathedral to nature’ opens

The Natural History Museum in South Kensington opened its doors on 18 April 1881. Its specimens, which began with Sir Hans Sloane’s collection in the 1750s, had long outgrown the British Museum in Bloomsbury.

Richard Owen, the first superintendent, wanted a free museum open to everyone, and Alfred Waterhouse gave it a building covered in terracotta animals and plants. It is now one of the world’s great centres of natural science research.

Yankee Stadium opens with a Ruth home run

The New York Yankees played their first game in their own stadium in the Bronx on 18 April 1923, beating the Boston Red Sox 4-1 in front of a record crowd. Babe Ruth, the reason so many fans came, hit a three-run home run into the right-field stands.

A sportswriter soon called it ‘the House That Ruth Built’. The ballpark hosted World Series, boxing title fights and papal masses before closing in 2008.

The first stone of the new St Peter’s

On 18 April 1506, Pope Julius II climbed down a ladder into a deep foundation pit in Rome and laid the first stone of a new St Peter’s Basilica. It was to replace the ageing church built under Constantine more than a thousand years earlier.

Donato Bramante drew the first plan, a vast Greek cross under a dome. Michelangelo, Maderno and others reshaped it over the next 120 years, and the finished basilica was consecrated in 1626.

International Day for Monuments and Sites

Also known as World Heritage Day, 18 April celebrates the world’s historic buildings and places. The idea came from a meeting of the heritage body ICOMOS in Hammamet, Tunisia, on 18 April 1982, and UNESCO adopted it the following year.

Each year ICOMOS picks a theme, and museums, sites and volunteers around the world hold tours, talks and open days.
