Spanish Dominican friar Tomas de Berlanga, bishop of Panama, became the first documented European to encounter the Galapagos Islands after ocean currents blew his ship off course en route to Peru. His accounts of the giant tortoises and unusual wildlife predated Charles Darwin's famous visit by three centuries.

King Charles I dissolves the English Parliament and begins eleven years of Personal Rule without summoning it again.

The dissolution followed years of bitter disputes over taxation, religion and royal authority, and Charles had three MPs physically held down in the Commons so a protest could be read before the session ended. His subsequent Personal Rule, funded through controversial measures like Ship Money, deepened resentment that eventually erupted into the English Civil War in 1642.

Following the death of his powerful chief minister, Cardinal Mazarin, the 22-year-old Louis XIV announced he would rule France without a prime minister, governing directly himself. His subsequent decades-long reign, marked by centralized absolute authority and the construction of Versailles, made him the archetype of European absolute monarchy.

The US Senate ratifies the Treaty of Guadalupe Hidalgo, formally ending the Mexican-American War.

Under the treaty, Mexico ceded roughly half its territory to the United States, including present-day California, Nevada, Utah, and parts of several other states, in exchange for $15 million and the assumption of certain debts. The vast territorial transfer reshaped the map of North America and set the stage for later disputes over slavery's expansion into the newly acquired lands.

Alexander Graham Bell successfully makes the first telephone call, reportedly saying "Mr. Watson, come here, I want to see you."

Working in his Boston laboratory, Alexander Graham Bell successfully transmitted clear speech to his assistant Thomas Watson in another room, reportedly saying "Mr. Watson, come here, I want to see you." The demonstration proved the telephone's practical viability just days after Bell had secured his patent.

Scottish-born inventor Alexander Graham Bell conducts the first successful test of the telephone, transmitting intelligible speech to his assistant Thomas Watson.

Bell's famous words, 'Mr. Watson, come here, I want to see you,' were spoken through the device just days after his patent had been granted. The test, conducted in Boston where Bell had settled, proved that the telephone could transmit clear speech rather than just tones, turning his patented invention into a working technology that would soon reshape communication worldwide.

An underground explosion at the Courrières coal mine in northern France kills 1,099 miners, the worst mining disaster in European history.

The blast, likely triggered by coal dust or firedamp, tore through kilometres of tunnels serving multiple pits, trapping workers including boys as young as thirteen. Rescue efforts were hampered by fires and toxic gas, and a small number of survivors were found alive nearly three weeks later. The disaster triggered a wave of miners' strikes across France demanding safer working conditions.

Siam cedes suzerainty over four northern Malay states to Britain under the Anglo-Siamese Treaty of 1909.

The agreement transferred the states of Kedah, Kelantan, Perlis and Terengganu from Siamese to British control in exchange for financial compensation and railway concessions, fixing the modern border between Thailand and Malaysia. The four states joined other British-controlled Malay territories, later forming part of the Federation of Malaya, which gained independence in 1957 and became modern Malaysia in 1963.

The arrest followed Gandhi's calls for non-cooperation with British rule, including a widely read editorial urging Indians to withdraw allegiance from the colonial government. He pleaded guilty at his trial, telling the court that resisting a government that had done more harm to India than any previous system was 'almost a religious duty.' He was sentenced to six years but released early in 1924.

Astronomers discover a system of rings around the planet Uranus.

Astronomers observing a stellar occultation from an airborne observatory unexpectedly detected a system of narrow rings encircling Uranus, making it only the second planet after Saturn known to have such a feature. The discovery prompted renewed interest in ring systems that was later confirmed by Voyager 2's 1986 flyby.

Astronomers discover that the planet Uranus is encircled by a system of rings, only the second planet known to have them after Saturn.

The rings were detected indirectly when Uranus passed in front of a distant star, and observers watched the star's light flicker several times before and after the planet itself blocked it, revealing narrow, previously unknown rings. The discovery, made using telescopes including one aboard a flying observatory, prompted a reassessment of how common planetary ring systems might be.

The crash, involving a Boeing 737 MAX, was the second fatal accident with the model in five months, following a similar crash of a Lion Air jet in Indonesia. Investigations pointed to a faulty automated flight-control system, prompting aviation regulators worldwide to ground the entire 737 MAX fleet for nearly two years while Boeing redesigned the system.

Silicon Valley Bank collapses and is seized by US regulators, the second-largest bank failure in American history.

The California-based lender, a major financier of technology startups, failed after a bond portfolio hit by rising interest rates and a rapid depositor run left it unable to meet withdrawal demands. Its collapse triggered fears of wider contagion in the banking sector, prompting emergency measures from US regulators to guarantee deposits and stabilise confidence in regional banks.
