August 21 in History

Congress passed the Hawaii Admission Act in March 1959, ending decades of plantation owner dominance by empowering immigrant descendants who held U.S. citizenship through their territory status. President Eisenhower signed the bill into law, triggering a 94.3% voter approval that transformed Hawaii from a contested territory into the fiftieth state. This shift dismantled the old political order, launching rapid modernization and establishing the Office of Hawaiian Affairs to protect indigenous culture within the new state framework.

Vincenzo Peruggia, an Italian handyman who had helped install the Mona Lisa's protective glass case, simply lifted the painting off its four iron pegs, hid it under his smock, and walked out of the Louvre on August 21, 1911. The theft wasn't discovered for over 24 hours because the museum had only 150 guards for 400 rooms. Pablo Picasso was questioned as a suspect. Poet Guillaume Apollinaire was arrested and jailed. Peruggia kept the painting in his apartment in Paris for two years before attempting to sell it to a Florentine art dealer, who alerted authorities. Peruggia claimed he was a patriot returning the painting to Italy. The theft made the Mona Lisa the most famous painting in the world; before 1911, it was just another Leonardo.

The Bois Caiman ceremony on the night of August 14, 1791, was a Vodou ritual led by Dutty Boukman, an enslaved man from Jamaica, that served as the signal for a coordinated slave uprising across the northern plain of Saint-Domingue (Haiti). Within a week, over 1,000 plantations were burning and hundreds of slaveholders had been killed. The French colony was the most profitable in the Caribbean, producing 40% of the world's sugar and 60% of its coffee through the labor of roughly 500,000 enslaved people. The uprising launched the Haitian Revolution, a thirteen-year struggle that ended with Haitian independence in 1804, making it the only successful slave revolt in history and the first Black republic in the Western Hemisphere.

General Arthur Wellesley (the future Duke of Wellington) defeated a French army under General Junot at Vimeiro on August 21, 1808, scoring the first significant Allied land victory of the Peninsular War. Wellesley employed the defensive tactics that would become his signature: positioning infantry on a reverse slope to shield them from artillery, then delivering devastating close-range volleys when the French columns crested the ridge. The battle demonstrated that well-disciplined British line infantry could consistently defeat French column attacks. Wellesley was prevented from pursuing the defeated French by his superiors, who negotiated the controversial Convention of Cintra allowing the French to evacuate Portugal with their weapons and loot intact.

Nat Turner, a literate enslaved preacher who believed he received divine visions, led between 50 and 75 enslaved and free Black people on a two-day rampage through Southampton County, Virginia, beginning on August 21, 1831. They killed 55 to 65 white men, women, and children before militia forces crushed the revolt. Turner evaded capture for two months before being found hiding in a hole under a fence. He was tried, convicted, and hanged. White mobs retaliated by killing an estimated 120 to 200 Black people, many of whom had no connection to the revolt. Southern states responded with draconian laws prohibiting the education of enslaved people, restricting their movement, and banning Black religious gatherings without white supervision.
