Michael Phelps breaks the record set in 1964 by Larisa Latynina for the most medals won at the Olympics.

Michael Fred Phelps II is an American former competitive swimmer. He won more Olympic medals than any other athlete, a total of 28 medals across four Olympic Games. Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16). At the 2004 Summer Olympics in Athens, Phelps tied the record of eight medals of any color at a single Games, held by gymnast Alexander Dityatin, by winning six gold and two bronze medals. Four years later, when he won eight gold medals at the 2008 Beijing Games, he broke fellow American swimmer Mark Spitz's 1972 record of seven first-place finishes at any single Olympic Games. At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro, he won five gold medals and one silver. This made him the most successful athlete of the Games for the fourth Olympics in a row.

Operation Banner, the presence of the British Army in Northern Ireland, and the longest-running British Army operation ever, comes to an end.

Operation Banner was the operational name for the British Armed Forces' operation in Northern Ireland from 1969 to 2007, as part of the Troubles. It was the longest continuous deployment in British military history. The British Army was initially deployed, at the request of the unionist government of Northern Ireland, in response to the August 1969 riots. Its role was to support the Royal Ulster Constabulary (RUC) and to assert the authority of the British government in Northern Ireland. This involved counter-insurgency and supporting the police in carrying out internal security duties such as guarding key points, mounting checkpoints and patrols, carrying out raids and searches, riot control and bomb disposal. More than 300,000 soldiers served in Operation Banner. At the peak of the operation in the 1970s, about 21,000 British troops were deployed, most of them from Great Britain. As part of the operation, a new locally-recruited regiment was also formed: the Ulster Defence Regiment (UDR).

Ranger program: Ranger 7 sends back the first close-up photographs of the moon, with images 1,000 times clearer than anything ever seen from earth-bound telescopes.

The Ranger program was a series of uncrewed space missions by the United States in the 1960s whose objective was to obtain the first close-up images of the surface of the Moon. The Ranger spacecraft were designed to take images of the lunar surface, transmitting those images to Earth until the spacecraft were destroyed upon impact. A series of mishaps, however, led to the failure of the first six flights. At one point, the program was called "shoot and hope". Congress launched an investigation into "problems of management" at NASA Headquarters and Jet Propulsion Laboratory. After two reorganizations of the agencies, Ranger 7 successfully returned images in July 1964, followed by two more successful missions.

USS Nevada is sunk by an aerial torpedo after surviving hits from two atomic bombs (as part of post-war tests) and being used for target practice by three other ships.

USS Nevada (BB-36), the third United States Navy ship to be named after the 36th state, was the lead ship of the two Nevada-class battleships. Launched in 1914, Nevada was a leap forward in dreadnought technology; four of her new features would be included on almost every subsequent US battleship: triple gun turrets, oil in place of coal for fuel, geared steam turbines for greater range, and the "all or nothing" armor principle. These features made Nevada, alongside her sister ship Oklahoma, the first US Navy "standard-type" battleships.

The Holocaust: Under instructions from Adolf Hitler, Nazi official Hermann Göring orders SS General Reinhard Heydrich to "submit to me as soon as possible a general plan of the administrative material and financial measures necessary for carrying out the desired Final Solution of the Jewish question."

The Holocaust, known in Hebrew as the Shoah, was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered around six million Jews across German-occupied Europe, approximately two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, Chełmno and Majdanek death camps in occupied Poland. Concurrent Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups, such as the Romani and Soviet POWs.

The NSDAP (Nazi Party) wins more than 38% of the vote in German elections.

The Nazi Party, officially the National Socialist German Workers' Party, was a far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party, existed from 1919 to 1920. The Nazi Party emerged from the extremist German nationalist, racist, and populist Freikorps paramilitary culture, which fought against communist uprisings in post–World War I Germany. The party was created to draw workers away from communism and into völkisch nationalism. Hitler stated while on trial for his role in the Beer Hall Putsch in February 1924 that “I have resolved to be the destroyer of Marxism”, a statement which he later applied to those opposed to the Nazi Party in 1926, claiming “They tried to paralyze the one party that would have been able to give opposition to this Red pest.” Initially, Nazi political strategy used socialist rhetoric to gain the support of the lower middle class; that was later downplayed to gain the support of business leaders. By the 1930s, the party's main focus shifted to antisemitic and anti-Marxist themes. The party had little popular support until the Great Depression, when worsening living standards and widespread unemployment drove Germans into political extremism.

Hundred Years' War: Battle of Cravant: A Franco-Scottish army is defeated by the Anglo-Burgundians at Cravant on the banks of the river Yonne.

The Hundred Years' War was a conflict between the kingdoms of England and France and a civil war in France during the late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years.

Attempted usurpation by John Komnenos the Fat for the throne of Alexios III Angelos.

John Komnenos, nicknamed "the Fat", was a Byzantine noble who attempted to usurp the imperial throne from Alexios III Angelos in a short-lived coup in Constantinople on 31 July 1201. The coup drew on opposition to the ruling Angelid dynasty among rival aristocratic families and the common people, who were dissatisfied by the dynasty's failures against external foes. John had previously been an obscure figure, but he became the figurehead of the uprising because of his imperial blood, as he was descended from the illustrious Komnenian dynasty (1081–1185). However, the real driving force behind his coup was probably the ambitious Alexios Doukas Mourtzouphlos. With the support of the capital's populace, the plotters managed to seize most of the Great Palace in Constantinople's southeastern corner, which the mob proceeded to loot, and John Komnenos was crowned in the Hagia Sophia. Alexios III, however, was secure in his residence in the northwestern Palace of Blachernae, and he sent forces by sea to land in the part of the Great Palace still held by the loyal Varangian Guard. Most of the urban mob dispersed for the night, and the Varangians had little difficulty in suppressing the coup. John Komnenos was captured and executed with many of his followers.

Battle of Alexandria: Mark Antony achieves a minor victory over Octavian's forces, but most of his army subsequently deserts, leading to his suicide.

The Battle of Alexandria was fought on July 1 to July 30, 30 BC between the forces of Octavian and Mark Antony during the last war of the Roman Republic. In the Battle of Actium, Antony had lost the majority of his fleet and had been forced to abandon the majority of his army in Greece, where without supplies they eventually surrendered. Although Antony's side was hindered by a few desertions, he still managed to narrowly defeat Octavian's forces in his initial defence. The desertions continued, however, and, in early August, Octavian launched a second, ultimately successful, invasion of Egypt, after which Antony and his lover, Cleopatra, committed suicide.
