November 12 in History

The dissolution of Austria-Hungary was a major political event that occurred as a result of the growth of internal social contradictions and the separation of different parts of Austria-Hungary. The more immediate reasons for the collapse of the state were World War I, the worsening food crisis since late 1917, general starvation in Cisleithania during the winter of 1917–1918, the demands of Austria-Hungary's military alliance with the German Empire and its de facto subservience to the German High Command, and its conclusion of the Bread Peace of 9 February 1918 with Ukraine, resulting in uncontrollable civil unrest and nationalist secessionism. The Austro-Hungarian Empire had additionally been weakened over time by a widening gap between Hungarian and Austrian interests. Furthermore, a history of chronic overcommitment rooted in the 1815 Congress of Vienna in which Metternich pledged Austria to fulfill a role that necessitated unwavering Austrian strength and resulted in overextension. Upon this weakened foundation, additional stressors during World War I catalyzed the collapse of the empire. The 1917 October Revolution and the Wilsonian peace pronouncements from January 1918 onward encouraged socialism on the one hand, and nationalism on the other, or alternatively a combination of both tendencies, among all peoples of the Habsburg monarchy.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated. Tanks and aircraft played major roles, the latter enabling the strategic bombing of cities and delivery of the only nuclear weapons used in war. World War II was the deadliest conflict in history, causing the death of 60 to 75 million people. Millions died as a result of massacres, starvation, disease, and genocides, including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Naval Battle of Guadalcanal took place from 12 to 15 November 1942 and was the decisive engagement in a series of naval battles between Allied and Imperial Japanese forces during the months-long Guadalcanal campaign in the Solomon Islands during World War II.

The war in Afghanistan was a prolonged armed conflict lasting from 2001 to 2021. It began with an invasion by a United States–led coalition under the name Operation Enduring Freedom in response to the September 11 attacks (9/11) carried out by the Taliban-allied and Afghanistan-based al-Qaeda. The Taliban were expelled from major population centers by American-led forces supporting the anti-Taliban Northern Alliance, thus toppling the Taliban-ruled Islamic Emirate. In 2004, the U.S.-backed Islamic Republic was established, but by then, the Taliban, led by founder Mullah Omar, had reorganized and begun an insurgency against the Afghan government and coalition forces. The conflict ended as the 2021 Taliban offensive reestablished the Islamic Emirate. It was the longest war in United States military history, surpassing the Vietnam War by six months.
