March 16

March 16 is the 76th day of the year, and the American record for it runs from 1782 to 2021 — a span of 239 years. The entry that anchors it: Mississippi formally ratifies the Thirteenth Amendment to the United States Constitution, 1995.

The revolutionary generation left its own mark on the date. In 1782, American Revolutionary War — Spain captured the island of Roatán from England off the coast of what is now Honduras.

The antebellum decades brought the date closer to the country’s central argument. In 1802, Congress passed the Military Peace Establishment Act, authorizing the establishment of the U.S. Army Corps of Engineers to operate the U.S. Military Academy at West Point, New York.

After 1945 the date reflects a country operating at global scale. In 1960, African American civil rights activists in Savannah, Georgia, conducted a sit-in, commencing the Savannah Protest Movement. Two years on, in 1962, Flying Tiger Line Flight 739, a charter flight carrying U.S. and South Vietnamese soldiers, disappeared without a trace, prompting one of the largest searches in the history of the Pacific. Then, in 1984, William Buckley, the U.S. Central Intelligence Agency station chief in Beirut, Lebanon, was kidnapped by Islamic fundamentalists.

The most recent entries fall within living memory. In 1995, Mississippi formally ratifies the Thirteenth Amendment to the United States Constitution, becoming the last state to approve the abolition of slavery. The Thirteenth Amendment was officially ratified in 1865. Then, in 2020, the Dow Jones Industrial Average falls by 2,997.10, the single largest point drop in history and the second-largest percentage drop ever at 12.93%, an even greater crash than Black Monday (1929). This follows the U.S. Federal Reserve announcing that it will cut its target interest rate to 0–0.25%. A year later, in 2021, Atlanta spa shootings — eight people are killed and one is injured in a trio of shootings at spas in and near Atlanta, Georgia, U.S. A suspect is arrested the same day.

The date is also a birthday. Among the Americans born on March 16: James Madison (1751), American academic and politician, 4th President of the United States; John Pope (1822), American general; Andrew Smith Hallidie (1836), English-American engineer and inventor; Rebecca Cole (1846), American physician and social reformer; and Patsy Donovan (1865), Irish-American baseball player and manager.

March 16 is also a date of endings. Among the Americans who died on it: Benjamin Wadsworth (1737), American minister and academic; Nathaniel Bowditch (1838), American ocean navigator and mathematician; David Wilmot (1868), American politician, sponsor of Wilmot Proviso; and Art Croft (1884), American baseball player.
