Months after a bloody siege and betrayal from within the walls, Crusader leaders spent the summer of 1098 solidifying control of Antioch, one of the great cities of the ancient Christian world. Bohemond of Taranto emerged as its ruler, founding the Principality of Antioch and setting a precedent of Crusader lords carving out personal fiefdoms rather than serving papal or Byzantine interests.
Captured near Glasgow weeks earlier, Wallace was dragged to Westminster Hall on August 22 and put through a show trial for treason and atrocities. Because he had never sworn fealty to Edward I, Wallace argued he could not be a traitor to a king he never served — a defense the court ignored. He was condemned to hanging, drawing, and quartering, executed the next day at Smithfield.
Trained as a physician, Marat became one of the French Revolution's most incendiary voices through his newspaper L'Ami du Peuple, demanding ever more radical action against perceived enemies of the Revolution. His relentless calls for violence against aristocrats and moderates helped fuel the September Massacres and the Terror. He was assassinated in his bath by Charlotte Corday in 1793, an image later immortalized by Jacques-Louis David.
Samuel Crompton's spinning mule, developed in the early 1780s by combining features of the spinning jenny and water frame, allowed British mills to produce thread fine and strong enough to rival imported Indian muslin. Too poor to patent his invention properly, Crompton saw it copied throughout Lancashire's booming textile industry, fueling the early Industrial Revolution while he received only a token parliamentary grant decades later for his contribution.
On the night of August 22, 1791, enslaved people across the Northern Plain of Saint-Domingue rose in coordinated revolt, burning plantations and killing enslavers after a secret Vodou ceremony at Bois Caïman reportedly sealed their pact days earlier. Within weeks, tens of thousands had joined the uprising. The revolt evolved into the Haitian Revolution, ending in 1804 with Haiti's independence as the first nation founded by a successful slave rebellion.
Following Guayaquil's declaration of independence from Spanish rule on October 9, 1820 would come later that year, but in the tense weeks of that same period, revolutionary leaders under José Joaquín de Olmedo worked to organize the fledgling free province and rally support across the region. Guayaquil became a crucial staging ground for the campaigns of Simón Bolívar and José de San Martín, whose famous 1822 meeting there shaped the future of Ecuador, Peru, and the broader continent's independence.
Kenyatta died in his sleep at his Mombasa residence at age 88 (his exact birth year remains uncertain), ending a presidency that began with Kenya's 1963 independence from Britain. Once imprisoned by colonial authorities for alleged links to the Mau Mau uprising, he became independent Kenya's founding leader, steering a pragmatic, Western-aligned course that brought stability but also entrenched one-party dominance. Vice President Daniel arap Moi succeeded him.
After a twelve-year, 4.4-billion-kilometer journey, Voyager 2 sent back stunning new imagery of Neptune in the days surrounding August 22, 1989, revealing swirling storm systems including the Great Dark Spot ahead of its closest approach on August 25. The flyby would be humanity's only close-up encounter with Neptune, capturing the planet's moon Triton and its faint ring system before the spacecraft continued outward into interstellar space.
