A journey through
25 July in history

The story of 25 July runs from the proclamation of Constantine at York in 306 to India’s first woman president in 2007. In between come the Byzantine recovery of Constantinople, the founding of Caracas, Mozart’s Symphony No. 40, the opening shots of the First Sino-Japanese War, American troops landing in Puerto Rico, Blériot’s flight across the Channel, the fall of Mussolini, an underwater atomic test at Bikini, the end of the monarchy in Tunisia, the exposure of the Tuskegee syphilis study, the birth of Louise Brown and the flaming arrow that opened the Barcelona Olympics.

Constantine is proclaimed emperor at York

The Roman emperor Constantius I had crossed to Britain with his son Constantine to campaign against the peoples of the far north. On 25 July 306 Constantius died at Eboracum, the Roman fortress that became York, and his soldiers at once acclaimed Constantine as emperor. It took him years of civil war to win the whole empire, but he went on to become the first Christian emperor and to found Constantinople.

A Byzantine general slips into Constantinople and ends the Latin Empire

In 1204 the knights of the Fourth Crusade sacked Constantinople and set up a Latin Empire there, while Byzantine princes fled to build rival states in exile. The strongest of them was the Empire of Nicaea in western Anatolia, and by 1261 its ruler, Michael VIII Palaiologos, had pushed the Latin emperor Baldwin II back to little more than the city itself. Constantinople’s great land walls still looked too strong to take by siege. In July 1261 Michael’s general Alexios Strategopoulos was near the city with only a small force, many of them Cuman horsemen. Local farmers told him that most of the Latin garrison and the Venetian fleet had sailed off to attack a nearby island. On the night of 25 July his men got inside, overpowered the guards and opened a gate, and the city fell almost without a fight. Baldwin fled by ship. Michael entered in triumph in August and was crowned in Hagia Sophia, and the restored Byzantine Empire lasted until 1453.

Diego de Losada founds Santiago de León de Caracas

The green valley below the Ávila mountain, a few miles inland from the Caribbean coast of Venezuela, was home to peoples the Spanish called the Caracas. Earlier Spanish attempts to settle there had been driven out. In early 1567 the conquistador Diego de Losada set out from El Tocuyo with a small, experienced force and fought his way into the valley against fierce resistance led by chiefs including Guaicaipuro. There he founded a city, very probably on 25 July 1567; no founding document survives, but 25 July is the feast of St James, and it is the day Caracas has always celebrated. He named it Santiago de León de Caracas, after the apostle James, the provincial governor Pedro Ponce de León and the valley’s native people. The small colonial town grew into the capital of Venezuela, the birthplace of Simón Bolívar and today a city of millions.

Mozart enters his Symphony No. 40 in his catalogue

From 1784 Mozart kept a small notebook in which he listed each new work as he finished it, with the date and the opening bars. In the summer of 1788, short of money and living in Vienna, he wrote his last three symphonies in about six weeks. The E flat symphony, No. 39, went into the notebook in June, and on 25 July 1788 he entered the Symphony No. 40 in G minor. It is one of only two symphonies Mozart wrote in a minor key, and its restless, urgent opening theme is among the most famous in classical music. Nobody knows for sure why he wrote the three symphonies or whether he heard No. 40 performed, although he later added clarinets to it, which suggests a performance was planned. His catalogue is now in the British Library.

Japanese warships open the First Sino-Japanese War off Korea

In 1894 China and Japan both sent troops into Korea, and each was determined to control it. On 25 July 1894, off the island of Pungdo near Asan Bay, Japanese cruisers attacked Chinese warships and sank the Kowshing, a British-owned steamer carrying more than 1,000 Chinese soldiers to Korea; most of the troops drowned. War was formally declared on 1 August, and Japan’s victory the next year announced it as a modern power.

American troops land in Puerto Rico at Guánica

During the Spanish-American War, General Nelson Miles led an expedition to seize Spain’s colony of Puerto Rico. Instead of landing near San Juan as expected, his ships sailed round to the south coast, and on 25 July 1898 about 3,000 men came ashore at Guánica after a brief skirmish. The campaign ended with the armistice in August, and at the peace treaty that December Spain handed Puerto Rico to the United States.

Louis Blériot flies across the English Channel

Only six years after the Wright brothers’ first powered flight, the London Daily Mail offered £1,000 to the first aviator to fly across the English Channel. By July 1909 three men were waiting on the French coast for the right weather. One of them was Louis Blériot, a French maker of car headlamps who had poured his fortune into flying machines, crashing many of them along the way. At dawn on 25 July 1909 he took off from Les Baraques, near Calais, in his Type XI, a small monoplane with a 25-horsepower Anzani engine. He carried no compass, lost sight of land in the haze and worried that rain would stop his engine. After about 36 minutes he spotted the cliffs of Dover and came down hard in a field near the castle, damaging his undercarriage and propeller. He was a hero overnight, and Britain realised that the sea no longer made it an island.

Mussolini is voted down and dismissed by the king

By the summer of 1943 Italy was losing the Second World War. Its armies had been driven out of North Africa, Allied troops landed in Sicily on 10 July, and Rome was bombed for the first time a few days later. Leading Fascists, army chiefs and the court all wanted to be rid of Benito Mussolini, who had ruled Italy for more than 20 years. On the evening of 24 July the Fascist Grand Council met for the first time since the war began. After a long night of argument it voted by a large majority for Dino Grandi’s motion asking King Victor Emmanuel III to take back his full powers. On the afternoon of 25 July the king received Mussolini, dismissed him and had him arrested as he left, naming Marshal Pietro Badoglio prime minister. Crowds celebrated in the streets. Mussolini was held on remote islands and then in a mountain hotel, until German commandos freed him in September.

The Baker test explodes an atomic bomb under Bikini lagoon

In 1946 the United States moved the people of Bikini Atoll in the Marshall Islands and anchored a fleet of old and captured warships in its lagoon to test the power of the atomic bomb against navies. On 25 July 1946 the second test, Baker, was set off about 90 feet under the water. It threw up a vast column of spray, sank eight ships and drenched much of the fleet in radioactive water, and the Bikinians have never been able to return to live there for good.

Tunisia abolishes its monarchy and becomes a republic

Tunisia had been ruled by beys of the Husaynid dynasty since 1705, and from 1881 they reigned under a French protectorate. Independence came in March 1956, won largely by the Neo-Destour party of the lawyer Habib Bourguiba, who became prime minister under the bey, Muhammad VIII al-Amin. The bey had little power, and Bourguiba had little patience for a monarchy many nationalists felt had done too little against French rule. On 25 July 1957 the Constituent Assembly voted to abolish the monarchy, declared Tunisia a republic and made Bourguiba head of state; the bey was confined to his house. Bourguiba, who as prime minister had already brought in a family law that banned polygamy and widened women’s rights, ruled as president for 30 years until he was removed in 1987. Republic Day on 25 July is a public holiday in Tunisia.

A news story exposes the Tuskegee syphilis study

From 1932 the US Public Health Service followed about 600 poor Black men in Macon County, Alabama, 399 of them with syphilis, to study the untreated disease. The men were told only that they had ‘bad blood’, and they were not offered penicillin even after it became the standard cure in the 1940s. On 25 July 1972 an Associated Press story by Jean Heller, based on a whistleblower’s evidence, revealed the study; the outcry ended it that year.

Louise Brown, the first IVF baby, is born in Oldham

Lesley and John Brown of Bristol had tried for years to have a child, but Lesley’s fallopian tubes were blocked. They were referred to Patrick Steptoe, a gynaecologist in Oldham, and Robert Edwards, a Cambridge physiologist, who had spent a decade trying to fertilise human eggs outside the body. Many scientists and churchmen thought the work was dangerous or wrong, and funding had been refused. Steptoe collected an egg from Lesley, Edwards fertilised it in a laboratory dish, and the embryo was placed in her womb about two and a half days later. On 25 July 1978 Louise Joy Brown was born by caesarean section at Oldham General Hospital, healthy and the focus of the world’s press. Since then millions of babies have been born by in vitro fertilisation. Edwards won the Nobel Prize in 2010; Steptoe had died in 1988.

A flaming arrow opens the Barcelona Olympics

The Barcelona Olympics were the first Summer Games after the end of the Cold War, and the first in decades without a boycott. Germany competed as one team again, athletes from the former Soviet Union took part as a Unified Team, and South Africa returned after more than 30 years of exclusion over apartheid. At the opening ceremony in the Olympic Stadium on Montjuïc on the evening of 25 July 1992, the basketball player Juan Antonio San Epifanio carried the torch to the Paralympic archer Antonio Rebollo. Rebollo lit an arrow and shot it high over the cauldron, igniting the flame before 67,000 spectators, a moment watched by hundreds of millions on television. The Games that followed helped transform Barcelona’s seafront and its reputation.
