A Seljuk Turkish army successfully fights off the People's Crusade at the Battle of Civetot.
Seljuk Turkish forces rout the ill-equipped People's Crusade at the Battle of Civetot in 1096. The defeat serves as a stark lesson in the perils of poorly led military expeditions.
In the spring of 1096, thousands of poorly armed peasants and minor nobles formed the People’s Crusade, separate from the main First Crusade. They marched into Anatolia, encamping at Civetot near Nicaea. On October 21, Seljuk Sultan Kilij Arslan launched a surprise attack. The Crusaders, lacking discipline and beaten in cavalry charges, were overwhelmed. Many were killed or captured, effectively ending the People’s Crusade as an independent force. The loss highlighted the necessity of proper military organization and foreshadowed the challenges ahead for the main Crusader armies.

First Crusade: Crusaders led by Godfrey of Bouillon, Bohemund of Taranto, and Raymond IV, Count of Toulouse, begin the Siege of Antioch.
Crusader leaders Godfrey of Bouillon, Bohemund, and Raymond IV commence the prolonged Siege of Antioch in October 1097. This pivotal siege marks a turning point in the First Crusade as they attempt to capture one of the Levant’s most fortified cities.
On October 21, 1097, a coalition of Crusader forces, led by Godfrey of Bouillon, Bohemund of Taranto, and Raymond IV of Toulouse, encircled the city of Antioch. Antioch was a key strategic bastion and major trading center in the Levant, protected by massive walls and towers. The siege involved constructing siege towers, tunneling operations, and blockading the city’s water supplies. Crusaders endured harsh conditions, disease, and supply shortages while resisting several sorties by the defending garrison under Yaghi Siyan. Bohemund’s diplomatic maneuvers with Armenian nobles within the city would later prove crucial. After an eight-month ordeal, the Crusaders would breach Antioch’s defenses in June 1098, but only after internal strife and near-starvation. The fall of Antioch paved the way for the eventual capture of Jerusalem and the establishment of Crusader states.

Japanese Emperor Go-Kameyama abdicates in favor of rival claimant Go-Komatsu.
Emperor Go-Kameyama abdicated in 1392, concluding the Nanboku-chō period and uniting the Northern and Southern Courts under Go-Komatsu. This abdication ended decades of imperial rivalry in Japan.
During the Nanboku-chō period of Japanese history (1336–1392), rival Southern and Northern Courts each claimed legitimate rule. Southern Court Emperor Go-Kameyama, based in Yoshino, faced persistent pressure from the Ashikaga shogunate to reconcile. On October 21, 1392, Go-Kameyama formally abdicated in favor of Northern Court claimant Emperor Go-Komatsu in Kyoto. This agreement, brokered by Shogun Ashikaga Yoshimitsu, ended decades of dynastic struggle. Go-Kameyama was granted estates and an honorable retirement. Go-Komatsu’s accession reunited the imperial lineage under a single sovereign for the first time in over half a century. The compromise reinforced the shogunate’s authority while restoring nominal harmony to the emperor’s role. However, southern loyalists would continue to remember Go-Kameyama’s legacy for generations.

Martin Luther joins the theological faculty of the University of Wittenberg.
In 1512, Martin Luther joined the theological faculty at the University of Wittenberg, launching his career as a leading church scholar. This appointment allowed him to teach and lecture on biblical texts, laying the foundation for the Reformation.
After earning his Doctor of Theology degree, Martin Luther was appointed to the theological faculty at the University of Wittenberg in October 1512. As a professor, Luther delivered lectures on biblical books such as the Psalms and the Epistle to the Romans. His scholarly approach combined rigorous study of ancient texts with a deep personal faith. Wittenberg became a vibrant center for theological debate and attracted students from across Europe. Luther’s work there prepared him for his later challenges to Church practices and doctrines. His lectures on justification by faith alone would soon spark the Protestant Reformation, reshaping Western Christianity. The university’s support gave Luther the academic credibility needed to publish his 95 Theses in 1517.

João Álvares Fagundes discovers the islands of Saint Pierre and Miquelon, bestowing them their original name of "Islands of the 11,000 Virgins".
Portuguese explorer João Álvares Fagundes sighted the islands of Saint Pierre and Miquelon in 1520, naming them the 'Islands of the 11,000 Virgins'. This voyage contributed to early European knowledge of Newfoundland’s coastal archipelago.
In 1520, under a Portuguese crown charter, explorer João Álvares Fagundes set sail to locate new fishing grounds in the North Atlantic. On October 21, he came upon two small islands south of Newfoundland, which he christened the 'Islands of the 11,000 Virgins' in honor of Saint Ursula and her companions. These isles are today known as Saint Pierre and Miquelon. Fagundes’s discovery provided fishermen with sheltered harbors and valuable cod stocks. Although the Portuguese did not settle the islands permanently, his reports spread knowledge of the region’s geography and resources. Over the following century, control passed to French interests, but the islands remained an important fishing outpost. Fagundes’s voyage represents an early chapter in European exploration of Canada’s Atlantic coast.

Tokugawa Ieyasu defeats the leaders of rival Japanese clans in the Battle of Sekigahara and becomes shōgun of Japan.
Tokugawa Ieyasu’s decisive victory at the Battle of Sekigahara in 1600 paved the way for his rule as shōgun, initiating over 250 years of Tokugawa shogunate. The battle ended decades of civil strife and unified Japan under a central military government.
The Battle of Sekigahara, fought on October 21, 1600, is often called the most important clash in Japanese history. Forces loyal to Tokugawa Ieyasu (Eastern Army) faced those allied with Toyotomi Hideyori under Ishida Mitsunari (Western Army) on the plains of Gifu. Strategic defections and superior tactics allowed Ieyasu to encircle and rout his opponents within hours. This decisive victory ended the Warring States period and removed the last major obstacle to Tokugawa dominance. In 1603, Ieyasu was appointed shōgun by Emperor Go-Yōzei, establishing the Tokugawa shogunate. Under his bakuhan system, Japan enjoyed over two centuries of relative peace and stability. The battle’s legacy endures as a symbol of military acumen and the birth of modern Japan.

The flag of Taunton, Massachusetts is the first to include the word "Liberty".
In 1774, citizens of Taunton, Massachusetts, raised the first known flag emblazoned with the word 'Liberty'. This emblem became a powerful symbol of colonial resistance leading up to the American Revolution.
Amid mounting tensions with British authorities, Taunton townsfolk unveiled a unique banner on October 21, 1774, bearing the inscription 'Liberty'. Historians regard this as the earliest documented flag in North America to feature the rallying cry. The design reflected the colonists’ growing defiance over taxation without representation. As news spread, the 'Liberty' motif inspired other communities to adopt similar flags and symbols. Printers like Isaiah Thomas later popularized the device through pamphlets and newspapers. By the time of the Revolution, the word 'Liberty' had become synonymous with American identity and the fight for independence. Taunton’s emblem thus stands as a precursor to the stars and stripes that would follow.

In Boston Harbor, the 44-gun United States Navy frigate USS Constitution is launched.
The USS Constitution, a 44-gun frigate destined to become the United States Navy’s flagship, was launched at Boston Harbor on October 21, 1797. Nicknamed 'Old Ironsides', she would earn fame in the War of 1812 for her resilience in battle.
Under the Naval Act of 1794, Joshua Humphreys designed the USS Constitution as one of the first six frigates of the United States Navy. On October 21, 1797, she slid into the waters of Boston Harbor amid celebrations and proud spectators. Constructed from live oak and white oak, the vessel earned its 'Old Ironsides' nickname during the War of 1812 when British cannonballs bounced off its hull. Constitution’s heavy armament and sturdy build allowed her to secure numerous victories against enemy ships. She also served as a flagship in multiple squadrons, projecting American naval power abroad. Over two centuries later, USS Constitution remains a commissioned ship and museum piece, symbolizing early US maritime heritage.

Portland cement is patented.
In 1824, British engineer Joseph Aspdin patented Portland cement, revolutionizing construction with a durable, fast-setting hydraulic binder. This innovation laid the groundwork for modern concrete structures worldwide.
Joseph Aspdin, a Leeds bricklayer and builder, secured a patent for Portland cement on October 21, 1824. By burning a mixture of limestone and clay to produce a fine powder, Aspdin created a hydraulic binder that set stronger than previous lime mortars. He named it 'Portland cement' because its color resembled the famous Portland stone quarried in Dorset, England. This invention enabled the rapid expansion of infrastructure, bridges, and industrial buildings during the 19th century. Portland cement became the primary ingredient in concrete, transforming architectural and engineering possibilities. Its durability and versatility laid the foundation for modern skyscrapers, roads, and dams around the world. Today, Portland cement remains the most widely used construction material globally.
