Mehmed II inherits the Ottoman throne, going on to conquer Constantinople two years later and end the Byzantine Empire.

Mehmed II inherited the Ottoman throne as a young teenager and quickly proved a formidable military strategist, orchestrating the 1453 siege that finally captured Constantinople after centuries of failed attempts by earlier Muslim rulers. The conquest ended the thousand-year-old Byzantine Empire and secured Ottoman control over a crucial crossroads between Europe and Asia.

Portuguese explorer Bartolomeu Dias becomes the first known European to round the southern tip of Africa, opening a sea route toward Asia.

Dias's voyage, commissioned by the Portuguese crown to find a sea route around Africa, was nearly cut short by a mutinous crew demanding to turn back. His discovery of the passage around what he named the "Cape of Storms," later renamed the Cape of Good Hope, opened the way for Vasco da Gama's historic voyage to India a decade later.

Speculative trading in tulip bulbs collapses in the Dutch Republic, an episode often cited as one of history's first recorded financial bubbles.

At the height of the speculative frenzy, single rare tulip bulbs sold for prices exceeding those of luxury homes, driven by a futures market in bulbs that hadn't even flowered yet. The sudden collapse wiped out fortunes overnight and is frequently cited by economists as an early cautionary example of speculative market bubbles.

The London Protocol formally establishes Greece as a fully independent, sovereign nation after its long war against Ottoman rule.

The protocol, negotiated by Britain, France, and Russia, formally recognized Greek independence after a lengthy war of liberation from the Ottoman Empire that had drawn sympathy and volunteers from across Europe, including the poet Lord Byron. It established Greece as a fully sovereign kingdom rather than an autonomous Ottoman province.

The Fifteenth Amendment to the U.S. Constitution is ratified, prohibiting the denial of voting rights based on race.

The amendment completed the Reconstruction-era trio of constitutional changes addressing slavery and citizenship, following the Thirteenth and Fourteenth Amendments. Despite its clear language, discriminatory practices like poll taxes and literacy tests were used for nearly a century afterward to suppress Black voting, particularly in the South, until the Voting Rights Act of 1965.

The United States severs diplomatic relations with Germany over its resumption of unrestricted submarine warfare, a major step toward American entry into World War I.

The break followed Germany's announcement that it would resume sinking merchant and passenger ships without warning, including those flying neutral flags, a policy that had previously outraged American public opinion after the sinking of the Lusitania. The severance of relations was a direct precursor to the U.S. declaration of war on Germany two months later.

Adolf Hitler privately outlines his goals for German expansion into Eastern Europe and the harsh subjugation of its populations.

Speaking privately to German army leaders shortly after becoming chancellor, Hitler laid out ambitions for conquering territory in the East to provide "living space" for the German population, foreshadowing the brutal occupation policies later carried out during the invasion of the Soviet Union. The speech offers early evidence of his expansionist and genocidal intentions.

Roughly 1,000 American bombers strike Berlin in one of the largest daylight bombing raids of World War II.

The raid was part of a sustained Allied strategic bombing campaign intended to cripple German industry and morale in the war's final months. Berlin, though repeatedly targeted throughout the war, endured some of its heaviest bombardment in these final months as Allied forces closed in from both east and west.

Musicians Buddy Holly, Ritchie Valens, and J. P. "The Big Bopper" Richardson die in a plane crash, an event later immortalized as "The Day the Music Died."

The three young musicians, all rising stars of early rock and roll, died when their chartered small plane crashed in an Iowa snowstorm shortly after takeoff. The tragedy, later commemorated in Don McLean's song "American Pie," is widely regarded as one of the first great losses in rock music history.

The Soviet probe Luna 9 achieves the first successful soft landing on the Moon, transmitting the first images from its surface.

Luna 9's landing, achieved after several earlier Soviet and American attempts had crashed or missed the Moon entirely, proved that a spacecraft could survive touchdown on the lunar surface without sinking into deep dust, a real concern among scientists at the time. The mission provided crucial data ahead of the crewed Apollo landings.
