September 12 in History: Microchips, Moon Race & Treaties
September 12 marks a significant date on the global calendar, observed as European Migraine Action Day, World First Aid Day, and the United Nations Day for South-South Cooperation. From the birth of modern computing to the shifting borders of empires, this day has witnessed pivotal moments in human history.
Historical Milestones
In 1297, King Dinis of Portugal and King Ferdinand IV of Leon and Castile signed the Treaty of Alcanizes, establishing the geographic borders of Portugal that remain largely intact today. Nearly a century later, in 1383, Portugal established the “Corpo de Quadrilheiros,” the nation’s first organized police force.
In 1873, the American company Remington began the industrial production of the first commercially successful typewriter, forever changing the landscape of professional and literary communication.
The mid-20th century saw rapid technological and political shifts. In 1958, Texas Instruments debuted the first microchip, the precursor to all modern computing. Just one year later, in 1959, the Soviet probe Lunik 2 became the first man-made object to reach the Moon. These achievements set the stage for U.S. President John F. Kennedy’s 1962 declaration that the United States would put a man on the moon by the end of the decade.
Global Politics and Conflict
World War II saw a turning point on this day in 1944 as the first American troops entered Germany. Decades later, in 1990, the Allied powers (UK, U.S., and USSR) formally ceded their occupation rights, paving the way for the Reunification Treaty between East and West Germany.
In 2001, following the 9/11 attacks, NATO Secretary General George Robertson affirmed that the alliance would stand by the U.S. under Article V, marking the first time the “attack on one is an attack on all” clause was invoked.
In 2005, the Israeli military completed its withdrawal from the Gaza Strip, ending 38 years of occupation. In 2022, IOM Director-General António Vitorino met with President Volodymyr Zelensky in Kyiv to address the humanitarian crisis caused by the ongoing war in Ukraine.
Arts, Literature, and Science
The literary world remembers Elizabeth Barrett and Robert Browning, who married in secret on this day in 1846. On the modern stage, the world mourned the loss of country music legend Johnny Cash in 2003 and acclaimed “Infinite Jest” author David Foster Wallace in 2008.
Scientific achievement was celebrated in 2009 with the legacy of Norman Borlaug, the father of the “Green Revolution,” who passed away at 95. More recently, in 2025, world-renowned pianist Maria João Pires was honored with the Helena Vaz da Silva European Award for her contributions to cultural heritage.
