Britain declares war on Germany over the invasion of Belgium

When war broke out between the great powers of Europe in the summer of 1914, Britain at first hesitated. It had understandings with France and Russia but no firm alliance obliging it to fight. What tipped the balance was Belgium. Under the Treaty of London of 1839 Britain, like Prussia, had promised to respect Belgian neutrality, and Germany’s war plan depended on marching through Belgium to strike at France.

German troops crossed the Belgian border on the morning of 4 August 1914. That afternoon the British government sent Berlin an ultimatum demanding that Belgian neutrality be respected, with a deadline of 11 p.m. London time. No satisfactory reply came, and when the deadline passed Britain was at war with Germany, bringing in the dominions and colonies of its empire with it. Crowds gathered outside Buckingham Palace that night. Few imagined that the fighting would last more than four years and cost millions of lives.

King Sebastian of Portugal dies at the Battle of the Three Kings

Sebastian became King of Portugal as a small child and grew up dreaming of a crusade in North Africa. In 1578, aged 24, he saw his chance when a deposed Moroccan sultan, al-Mutawakkil, asked for help against his uncle, the Saadian sultan Abd al-Malik. Against much advice, Sebastian landed with an army of about 20,000 men, weighed down with artillery and baggage, and marched inland.

On 4 August 1578 the two sides met near Ksar el-Kebir, known to the Portuguese as Alcácer Quibir. The Moroccan army was far larger, and the Portuguese were routed; many drowned trying to cross a river swollen by the tide. Sebastian and al-Mutawakkil were both killed, and Abd al-Malik, already gravely ill, also died, giving the battle its name. Sebastian left no heir, and two years later Philip II of Spain took the Portuguese crown. Many Portuguese refused to believe their king was dead and long awaited his return.

The French Assembly abolishes feudal privilege in a single night

In the weeks after the fall of the Bastille a wave of rumour and panic, the Great Fear, swept the French countryside. Peasants attacked châteaux and burned the records of the dues they owed their lords. The deputies of the new National Assembly at Versailles, many of them landowners, needed a way to calm the countryside without simply sending in troops.

On the evening of 4 August 1789 liberal nobles rose to give up their own feudal rights, and the mood caught fire. Through the night, deputy after deputy renounced privileges: labour services, lords’ courts and hunting rights, church tithes, the sale of public offices and the special rights of provinces and towns. The decrees were written up over the following days and finalised on 11 August. Many dues were to end only when peasants paid compensation, but the night of 4 August is remembered as the end of the old feudal order in France.

Anne Frank and the people in the Secret Annex are arrested

In July 1942, as the deportation of Jews from the occupied Netherlands began, the Frank family went into hiding in rooms at the back of Otto Frank’s business premises at Prinsengracht 263 in Amsterdam. Four more people later joined them. The entrance was hidden behind a movable bookcase, and a small group of Otto Frank’s staff brought them food and news. For two years Anne, who turned 13 just before going into hiding, kept a diary.

On the morning of 4 August 1944 police led by an SS officer, Karl Silberbauer, entered the building, found the entrance to the annex and arrested all eight people in hiding, along with two of their helpers. How the police came to search the building has never been settled. The eight were sent to Westerbork and then to Auschwitz. Anne and her sister Margot died at Bergen-Belsen in early 1945; only Otto Frank survived. Miep Gies had saved Anne’s diary, and it was published in 1947.

Upper Volta becomes Burkina Faso

The West African state of Upper Volta, named after the upper reaches of the Volta river, won its independence from France in 1960. Its first decades were marked by poverty and a series of military coups. On 4 August 1983 a young army captain, Thomas Sankara, seized power at the head of a radical National Revolutionary Council, promising to fight corruption and make the country less dependent on foreign aid.

Exactly a year later, on 4 August 1984, Sankara gave the country a new name: Burkina Faso, made from words in two of its main languages and usually translated as ‘land of incorruptible people’ or ‘land of upright people’. A new flag and anthem followed. Sankara launched mass vaccination and tree-planting campaigns and championed women’s rights, but ruled without elections and was killed in a coup in 1987. The name he chose has remained.

NASA’s Phoenix lander sets off for the Martian Arctic

Phoenix took its name from the mythical bird that rises from its own ashes: it was built partly from a lander prepared for an earlier Mars mission that had been cancelled. Its target was the frozen plains near the planet’s north pole, where orbiting spacecraft had detected signs of water ice just below the surface.

Phoenix lifted off on a Delta II rocket from Cape Canaveral in Florida before dawn on 4 August 2007. It landed on 25 May 2008, farther north than any spacecraft before it, and its robotic arm soon dug trenches that exposed bright patches of ice, which slowly vanished in the thin Martian air. The lander confirmed that water ice lay just beneath the soil and analysed the soil’s chemistry, until the Martian winter cut off its power later in 2008.

Fangio wins the German Grand Prix in the drive of his life

The Argentine driver Juan Manuel Fangio was 46 and already a four-time world champion when he arrived at the Nürburgring in 1957. The circuit’s Nordschleife, more than 22 kilometres of twisting road through the Eifel forests, was the most demanding in motor racing. Fangio’s Maserati started with a half-full tank, planning to build a lead and then stop for fuel and tyres, while the Ferraris of Mike Hawthorn and Peter Collins ran without a stop.

The plan went wrong when his pit stop on 4 August 1957 took far longer than expected, and Fangio rejoined almost a minute behind the two Ferraris. He then broke the lap record again and again, taking corners in higher gears than he had ever dared, caught the pair and took the lead on the penultimate lap. The win sealed his fifth world championship. It was the last of his 24 Grand Prix victories, and many still call it the greatest drive in Formula One history.

Mozart marries Constanze Weber in Vienna

In 1781 Wolfgang Amadeus Mozart broke with his employer, the Archbishop of Salzburg, and settled in Vienna to make his living as a freelance composer, performer and teacher. He took lodgings with the Weber family, whom he had known for years; he had once been in love with the second daughter, the singer Aloysia. Now he fell for her younger sister Constanze, to the dismay of his father, Leopold.

The couple married in St Stephen’s Cathedral on 4 August 1782, a few weeks after the premiere of Mozart’s opera The Abduction from the Seraglio, whose heroine is also called Constanze. They had six children, of whom only two survived infancy. The marriage lasted until Mozart’s death in 1791. Constanze then worked hard to promote and publish his music, and with her second husband, Georg Nikolaus von Nissen, gathered material for one of the first biographies of the composer.

Constitution Day, Cook Islands

The Cook Islands, 15 islands scattered across a wide stretch of the South Pacific, were annexed by New Zealand in 1901. On 4 August 1965 they became self-governing in free association with New Zealand, with their own elected parliament and a premier, Albert Henry, while Cook Islanders kept New Zealand citizenship.

The anniversary is marked with Te Maeva Nui, a week-long festival in early August in which teams from the islands compete in dance, drumming, song and costume in Rarotonga, the main island.

Coast Guard Day, United States

On 4 August 1790 President George Washington signed an act, proposed by Treasury Secretary Alexander Hamilton, that paid for ten boats to enforce customs laws and stop smuggling. This small force, later known as the Revenue Cutter Service, was for some years the young republic’s only naval force.

In 1915 it merged with the Life-Saving Service to form the United States Coast Guard, which counts 4 August 1790 as its birthday and marks Coast Guard Day every year.
