Today in History — Monday, August 3.
1492 — Christopher Columbus, with Juan de la Cosa serving as second-in-command, sets sail on his first transatlantic voyage from Palos de la Frontera, Spain. His small fleet comprised three ships — the Santa María, the Pinta, and the Niña — bound westward for what Columbus believed would be the "Indies." The expedition was financed in large part by the Spanish Crown under King Ferdinand II of Aragon and Queen Isabella I of Castile. Columbus would ultimately complete four voyages to the Americas, never reaching the Asian destinations he sought but opening a sustained period of European exploration and colonization of the Western Hemisphere.
1596 — German astronomer and Lutheran priest David Fabricius discovers the light variation of Mira (Omicron Ceti), making it the first recognized variable star. Mira's brightness fluctuates dramatically over a period of roughly 332 days, a phenomenon later studied in greater detail by his son, Johannes Fabricius. The star's name, derived from the Latin word for "wonderful," became the prototype for an entire class of long-period pulsating variables known as Mira variables, of which thousands have since been identified.
1914 — Germany invades Belgium and declares war on France, dramatically widening the conflict that would become known as World War I. The invasion followed the Schlieffen Plan, a strategic framework calling for a rapid advance through neutral Belgium to outflank French defenses before turning east to face Russia. The violation of Belgian neutrality prompted Britain to declare war on Germany the following day.
1934 — Adolf Hitler merges the offices of German Chancellor and President into a single position following the death of President Paul von Hindenburg, declaring himself "Führer" (leader) of the German Reich. The consolidation effectively ended the Weimar Republic's constitutional structure and removed the last institutional check on Nazi authority within the German state.
1967 — An additional 45,000 U.S. soldiers are deployed to Vietnam, escalating American military involvement in the conflict under President Lyndon B. Johnson. The buildup was part of a steady increase in U.S. ground forces that would peak at over 500,000 troops the following year, making Vietnam the largest American military commitment since the Korean War.
1972 — The U.S. Senate ratifies the Anti-Ballistic Missile (ABM) Treaty with the Soviet Union, an agreement reached during the Strategic Arms Limitation Talks (SALT I). The treaty limited each nation to two ABM deployment areas designed to defend against missile-delivered nuclear weapons. The ABM Treaty remained a cornerstone of U.S.-Soviet nuclear arms control for three decades until the United States formally withdrew in June 2002 to pursue national missile defense systems.
2001 — U.S. President George W. Bush signs into law the Iran and Libya Sanctions Act (ILSA) Extension Act of 2001, extending sanctions originally enacted in 1996 against foreign companies investing in the energy sectors of Iran and Libya. The legislation was later renamed the Iran Sanctions Act (ISA) in 2006 after sanctions on Libya were lifted following that country's 2003 renunciation of weapons of mass destruction.
