September 24 is noted for various historical milestones across religious, economic, geopolitical, and industrial sectors.

In religious history, the year 622 saw the completion of the Hijra, marking the start of the Islamic calendar, and in 787, the 7th Ecumenical Council convened in Nicaea.

Geopolitical events include the 1973 recognition of Guinea-Bissau’s independence, the 1971 expulsion of 90 Soviet diplomats by the British government following espionage allegations, and the 1664 transfer of New Amsterdam from the Dutch to England, which was subsequently renamed New York.

Economic history highlights the 1869 ‘Black Friday’ in the United States, where attempts by speculators Jay Gould and James Fisk to manipulate the gold market led to a major stock market crash. In 1789, President George Washington signed the Judiciary Act, establishing the federal court system and the U.S. Supreme Court.

Other milestones include the 1493 start of Christopher Columbus’s second expedition, the 1828 establishment of the first Greek postal service, and the 1908 union of Crete with Greece.

Industrial, scientific, and cultural notes include the 1948 founding of the Honda Motor Company, Jimmy Doolittle’s first successful blind instrument flight in 1929, and the release of Nirvana’s ‘Nevermind’. Notable births include F. Scott Fitzgerald and Baron Florey.
