November 16

Prince Edward becomes King of England upon the death of his father, Henry III, though he is away on crusade and not crowned for nearly two years.

Edward learned of his accession while returning from the Ninth Crusade and took his time travelling home through Europe, confident enough in the peace of his realm to delay his coronation until August 1274. He would reign as Edward I, remembered as 'Longshanks' for his conquests in Wales and wars against Scotland.

Francisco Pizarro's forces capture Inca Emperor Atahualpa at the Battle of Cajamarca, a turning point in the Spanish conquest of Peru.

The Battle of Cajamarca saw Pizarro's small force ambush Atahualpa's much larger but unprepared retinue, capturing the Inca emperor and killing thousands of his followers with minimal Spanish casualties, thanks to superior weaponry and the element of surprise. His subsequent capture and eventual execution effectively decapitated Inca resistance, accelerating the Spanish conquest of the empire.

Spanish conquistador Francisco Pizarro and his men capture the Inca emperor Atahualpa at the Battle of Cajamarca.

Despite being vastly outnumbered, Pizarro's small force ambushed Atahualpa's unarmed retinue, killing thousands of Inca attendants and taking the emperor hostage. Atahualpa's capture and subsequent execution the following year opened the way for the Spanish conquest of the Inca Empire.

King Gustavus Adolphus of Sweden is killed at the Battle of Lützen during the Thirty Years' War.

King Gustavus Adolphus of Sweden, one of the most celebrated military innovators of his era, was killed leading a cavalry charge at the Battle of Lutzen during the Thirty Years' War, though his forces ultimately won the engagement. His death removed a formidable Protestant leader from the conflict but did not immediately alter Sweden's continued involvement in the war.

British forces capture Fort Washington from Patriot defenders during the American Revolutionary War.

British and Hessian forces overwhelmed the American garrison defending Fort Washington on Manhattan Island, resulting in the capture of nearly 3,000 Continental Army soldiers, one of the most significant American defeats of the entire Revolutionary War.

British and Hessian forces capture Fort Washington on Manhattan Island, dealing a heavy blow to George Washington's Continental Army.

The assault overwhelmed the fort's garrison and netted nearly 3,000 American prisoners along with valuable artillery and supplies, one of the worst American defeats of the Revolutionary War. The loss forced Washington's army into a difficult retreat across New Jersey that winter, though it survived to fight on.

Britain, France, and Russia sign the London Protocol, agreeing to establish an autonomous Greek state under nominal Ottoman suzerainty.

The agreement followed the three powers' naval intervention at the Battle of Navarino the previous year, which had crippled the Ottoman-Egyptian fleet during the Greek War of Independence. The protocol paved the way for full Greek independence, recognised two years later, and marked Britain's growing role as an arbiter of the Eastern Mediterranean's affairs.

Explorer David Livingstone becomes the first European to see Victoria Falls in present-day Zambia-Zimbabwe.

David Livingstone became the first European recorded to see the massive waterfall on the Zambezi River, naming it Victoria Falls in honor of the British monarch, though local peoples had known the site for generations under different names. His accounts of the falls' scale and power sparked significant European interest in exploring the African interior.

Scottish missionary and explorer David Livingstone becomes the first European to see the waterfall on the Zambezi River he names Victoria Falls.

Local Kololo guides knew the falls as Mosi-oa-Tunya, 'the smoke that thunders,' and Livingstone renamed them in honour of Queen Victoria. His account of the falls, among the largest in the world, captivated Victorian Britain and cemented his reputation as the era's most celebrated African explorer.

Twenty-four Victoria Crosses are awarded for actions during the relief of Lucknow, the most ever presented for a single day's fighting.

The medals recognised acts of extraordinary bravery during the Indian Rebellion of 1857, as British and loyal Indian forces fought to break the siege of the Lucknow Residency. Instituted the previous year, the Victoria Cross remains Britain's highest award for gallantry in the presence of the enemy.

English engineer John Ambrose Fleming receives a patent for the thermionic valve, the first practical vacuum tube.

Fleming's diode, developed while consulting for the Marconi Company, allowed alternating current to be converted into a detectable direct current signal, making it essential for early radio receivers. The device launched the field of electronics and remained central to radio, television, and computing technology until the transistor's invention decades later.

The Federal Reserve Bank of the United States officially opens, establishing the nation's central banking system.

The Federal Reserve system began operations following passage of the Federal Reserve Act the previous year, establishing a network of regional reserve banks intended to provide the United States with a more stable and elastic currency and banking system. The system was created partly in response to recurring financial panics that had destabilized the American economy in preceding decades.

Chemist Albert Hofmann first synthesizes LSD from ergotamine at Sandoz Laboratories in Basel, Switzerland.

Chemist Albert Hofmann first synthesized LSD while researching potential medicinal compounds derived from a fungus that grows on rye, though its powerful psychoactive properties were not discovered until he accidentally absorbed a small amount several years later. The substance would go on to play a significant, controversial role in psychiatric research and 1960s counterculture.

The Royal Air Force bombs Hamburg in retaliation for the devastating German raid on Coventry days earlier.

The strike was part of an escalating cycle of night bombing between Britain and Germany during the early stages of the Blitz, as both air forces targeted each other's industrial cities. Hamburg, a major port and shipbuilding centre, would go on to suffer far larger Allied raids later in the war, including the devastating 1943 firestorm of Operation Gomorrah.

UNESCO is established as an international organization for education, science, and cultural cooperation.

UNESCO was founded in the aftermath of World War II to promote international collaboration in education, science, and culture as a means of building lasting peace through mutual understanding between nations. The organization has since become known for initiatives including its World Heritage Site designation program, which recognizes places of outstanding cultural or natural significance.

The United Nations Educational, Scientific and Cultural Organization is founded in London.

Established in the aftermath of the Second World War, UNESCO was created to promote international cooperation in education, science, and culture as a means of building lasting peace. It went on to establish the World Heritage List and numerous other programmes protecting cultural and natural sites around the globe.

NASA launches Skylab 4, sending a crew of three astronauts on an 84-day mission.

Skylab 4's crew conducted the longest crewed spaceflight to date at the time, spending 84 days aboard America's first space station while performing extensive scientific research, including detailed observations of the Sun and Comet Kohoutek. The mission also gained notoriety for a brief crew strike over a demanding workload imposed by mission control.

Metal detectorist Eric Lawes discovers the Hoxne Hoard in Suffolk, the largest hoard of late Roman gold and silver ever found in Britain.

Searching for a friend's lost hammer, Lawes instead unearthed nearly 15,000 Roman coins along with gold jewellery and silver tableware, buried around 410 AD as Roman rule in Britain collapsed. Now held by the British Museum, the hoard offered an unprecedented window into wealth and daily life in Roman Britain's final years.

NASA launches Artemis 1, an uncrewed test flight beginning the program's return to the Moon.

Artemis 1 launched as an uncrewed test flight of NASA's new Space Launch System rocket and Orion spacecraft, sending the capsule on a journey around the Moon to validate systems before future crewed missions. The successful mission marked the beginning of NASA's renewed effort to return astronauts to the lunar surface after a decades-long absence.
