The Chalcedonian Creed, regarding the divine and human nature of Jesus, is adopted by the Council of Chalcedon, an ecumenical council.
The Council of Chalcedon in 451 adopts the Chalcedonian Creed, defining Christ’s divine and human natures and shaping Christian orthodoxy.
The Council of Chalcedon, convened in 451 in present-day Turkey, was the fourth ecumenical council of the early Christian church. It aimed to settle disputes over the nature of Christ, which had divided bishops and emperors. The resulting Chalcedonian Creed declared that Jesus Christ exists in two natures, fully divine and fully human, united in one person without confusion or separation. This definition became the standard for both Eastern Orthodox and Western churches and remains a cornerstone of mainstream Christian theology. However, it also led to schisms with churches that rejected the council’s conclusions, such as the Oriental Orthodox churches. The creed influenced the relationship between church and state in the Byzantine Empire and solidified theological orthodoxy. Its impact continues to be felt in modern Christian doctrine and ecumenical dialogues.

Japanese Emperor Kanmu relocates his empire's capital to Heian-kyō (now Kyoto).
Emperor Kanmu relocates Japan’s capital to Heian-kyō (modern Kyoto) in 794, ushering in the Heian period.
In 794, Emperor Kanmu officially moved the seat of the Japanese imperial court from Nara to Heian-kyō, marking a strategic shift in political and religious influence. Heian-kyō was laid out on a grid pattern inspired by Chinese capitals and designed to accommodate the growing court bureaucracy. This relocation reduced the power of Buddhist monasteries in Nara and strengthened imperial authority. The move initiated the Heian period, renowned for its flourishing of Japanese art, literature, and court culture. Over the next several centuries, the city became a hub for poetry, painting, and refined aristocratic life. Many of the traditions and aesthetic sensibilities developed during this era still influence Japan today. Modern Kyoto preserves numerous historical sites from this foundational period.

Abbasid general Ahmad ibn Kayghalagh leads a raid against the Byzantine Empire, taking 4,000–5,000 captives.
In 906, Abbasid general Ahmad ibn Kayghalagh raids Byzantine territories, capturing thousands of civilians.
In 906, Ahmad ibn Kayghalagh, a leading general of the Abbasid Caliphate, led a bold raid against the Byzantine frontier. His forces penetrated deep into Anatolian provinces, targeting towns and fortifications. The campaign resulted in the seizure of four to five thousand Byzantine citizens, who were taken as prisoners. Such incursions were part of the ongoing Muslim–Byzantine border conflicts in the early tenth century. These raids weakened border defenses and disrupted local economies. Captives were often sold into slavery or ransomed back, fueling further cycles of violence. The raid exemplified the ebb and flow of power along the medieval Near Eastern frontier.

The male line of the Portuguese House of Burgundy becomes extinct with the death of King Fernando, leaving only his daughter Beatrice. Rival claimants begin a period of civil war and disorder.
The death of King Fernando in 1383 ends Portugal’s Burgundian male line and triggers a dynastic crisis and civil war.
In 1383, King Fernando I of Portugal died without a male heir, bringing the male line of the Portuguese House of Burgundy to an end. His daughter Beatrice’s claim to the throne, tied to her marriage to the Castilian prince, provoked strong opposition among Portuguese nobles. Rival claimants, most notably John, Master of Avis, contested her succession. The dispute escalated into the 1383–1385 Crisis, a period of civil war and political instability across Portugal. Key battles and shifting alliances determined control over strategic fortresses. The conflict concluded with John of Avis’s victory and coronation as King John I, founding the Avis dynasty. This resolution secured Portuguese independence and set the stage for the nation’s Age of Discoveries.

Construction of the Ladoga Canal is completed in Russia.
Construction of Russia’s Ladoga Canal, completed in 1730, improves navigation between the Neva and Volkhov rivers.
Completed in 1730, the Ladoga Canal was built along the southern shore of Lake Ladoga to connect the Neva and Volkhov rivers and bypass the lake’s treacherous waters. The project, initiated under Peter the Great, faced challenging terrain and harsh climate conditions during its seven-year construction. The canal provided a safer and more reliable trade route to the newly founded city of St. Petersburg. It played a vital role in boosting inland commerce and integrating Russia’s waterways. Over time, the canal became part of a larger network linking the Baltic Sea with Russia’s interior. Though larger modern canals have since taken precedence, the Ladoga Canal remains an important historical landmark of early Russian engineering.

The War of Jenkins' Ear begins with the first attack on La Guaira.
The War of Jenkins’ Ear begins in 1739 with a British attack on the Spanish port of La Guaira.
On October 22, 1739, Britain formally declared war on Spain in what became known as the War of Jenkins’ Ear, named after a naval incident involving Captain Robert Jenkins. The conflict started with a British expeditionary force attacking the fortified Venezuelan port of La Guaira. Underlying the war were disputes over trade rights, tariffs, and maritime jurisdiction in the Caribbean. British merchants sought to expand their influence and challenge Spanish naval superiority. Early engagements focused on capturing Spanish ports and disrupting shipping lanes. The war ultimately merged into the larger War of the Austrian Succession and ended inconclusively in 1748. Despite its limited strategic gains, the conflict heightened imperial rivalries in the Americas.

The College of New Jersey (later renamed Princeton University) receives its charter.
The College of New Jersey, later Princeton University, receives its charter in 1746, establishing a leading colonial college.
In 1746, the College of New Jersey was chartered by New Light Presbyterians seeking an institution of higher learning in the American colonies. Classes initially met in a simple log cabin before the college acquired land in Princeton and built Nassau Hall. The charter emphasized academic freedom and governance by both faculty and students. Early professors and trustees included influential figures who later became Founding Fathers. The college quickly gained a reputation for excellence in theology, philosophy, and the liberal arts. Princeton alumni played significant roles in the American Revolution and the early republic. Today, Princeton University is renowned for its scholarly achievements and historic campus.

André-Jacques Garnerin makes the first recorded parachute jump, from 1,000 metres (3,300 ft) above Paris.
French aeronaut André-Jacques Garnerin makes the first recorded parachute jump from 1,000 metres above Paris.
On October 22, 1797, French balloonist André-Jacques Garnerin performed what is recognized as the first parachute descent.
Launching from a hydrogen balloon at approximately 1,000 metres (3,300 feet) over Paris, he descended safely using a 23-foot silk parachute.
Garnerin’s design lacked a rigid frame, relying on air inflation to maintain shape.
This daring experiment proved that humans could safely return from high altitudes.
His successful landing inspired further research into aerial safety and paved the way for modern parachuting techniques.
Garnerin’s flight captured public imagination and advanced both aeronautics and popular entertainment in the late 18th century.
