The Kingdom of Hawaii is overthrown in a coup led by American and European businessmen.

American sugar planters and businessmen, backed by U.S. Marines landed from a nearby warship, orchestrated the overthrow of Queen Liliuokalani, ending the Hawaiian monarchy. The coup paved the way for U.S. annexation of Hawaii five years later, an act the United States formally apologized for in 1993, acknowledging it had been carried out without the consent of the Hawaiian people.

Scott's British expedition reached the South Pole only to discover a Norwegian flag left by Roald Amundsen's team, which had arrived over a month earlier using a faster route and sled dogs. Devastated, Scott and his four companions died of starvation and exposure during their return journey, their fate becoming a defining, tragic story of the heroic age of Antarctic exploration.

Prohibition begins in the United States as the Volstead Act takes effect, banning the sale of alcohol.

The Volstead Act provided the legal enforcement mechanism for the 18th Amendment, banning the sale, manufacture, and transport of alcoholic beverages across the United States. Rather than eliminating alcohol consumption, Prohibition drove the trade underground, fueling organized crime syndicates like Al Capone's and ultimately proving so unpopular and difficult to enforce that it was repealed in 1933.

Soviet forces liberate Warsaw from German occupation during World War II.

The Red Army's liberation of Warsaw came after the city had been devastated by German forces the previous year in retaliation for the Warsaw Uprising, an occupation during which roughly 85 percent of the city was deliberately destroyed. Soviet troops found a largely empty, ruined capital, and Poland's postwar reconstruction and political future would soon fall under Soviet-dominated communist control.

The United Nations Security Council holds its first-ever session.

Delegates from the UN Security Council's founding members convened for the first time in London, working to establish procedures for the body tasked with maintaining international peace under the new United Nations Charter.

A B-52 bomber collides with a refueling tanker over Palomares, Spain, accidentally dropping four nuclear bombs.

During a mid-air refueling attempt gone wrong, the bomber and tanker collided, killing seven crew members and scattering wreckage, including four hydrogen bombs, near the Spanish fishing village of Palomares. Three bombs were recovered relatively quickly, but the fourth, lost in the Mediterranean Sea, took over two months of searching by a specialized submarine to locate and retrieve.

A U.S.-led coalition launches Operation Desert Storm with airstrikes against Iraqi targets.

The coalition's opening air assault, involving thousands of sorties against Iraqi military targets, infrastructure, and command centers, marked the start of the Gulf War proper following Iraq's refusal to withdraw from Kuwait. The overwhelming display of precision-guided munitions and airpower, broadcast live on television, showcased a new era of high-tech warfare to a global audience.

The magnitude 6.7 Northridge earthquake strikes the Los Angeles area, causing dozens of deaths and billions in damage.

The Northridge earthquake struck a densely populated area of Los Angeles in the early morning, collapsing freeway overpasses and apartment buildings and killing 57 people despite California's relatively strict seismic building codes. It remains one of the costliest natural disasters in U.S. history and prompted significant revisions to building and infrastructure retrofitting standards.

The magnitude 6.9 Great Hanshin earthquake devastates Kobe, Japan, killing thousands.

The Great Hanshin earthquake devastated the port city of Kobe, collapsing highways, buildings, and rail lines and killing more than 6,000 people, exposing gaps in Japan's earthquake preparedness despite its reputation for strict building codes. The disaster prompted a major overhaul of Japan's emergency response systems and construction standards in the years that followed.
