Carloman I and Charlemagne are crowned kings of the Franks.
Carloman I and Charlemagne are jointly crowned kings of the Franks, inaugurating a pivotal era in early medieval Europe.
In 768, following the death of their father Pepin the Short, Carloman I and Charlemagne were anointed as co-rulers of the Frankish kingdom. The joint coronation formalized the division of power between the brothers and reinforced their legitimacy among Frankish nobles and the Church. Charlemagne would later expand Frankish territories and become Emperor of the Romans, while Carloman’s premature death in 771 reunited the realm under Charlemagne’s sole leadership. This event marks the beginning of the Carolingian era, which saw cultural revival and political consolidation across Western Europe. The brothers’ alliance and eventual rivalry significantly influenced the development of medieval European governance and religious relations.

Valencia rapidly grew into a center of Mediterranean trade, culture, and agriculture under Aragonese rule. Its unique blend of Christian, Islamic, and Jewish influences shaped the region’s architecture and society. The Kingdom of Valencia remained an influential political entity until its incorporation into the Spanish crown in the modern era.

Roger Williams is banished from the Massachusetts Bay Colony after religious and policy disagreements.
Roger Williams is expelled from Massachusetts Bay Colony for championing religious freedom and separation of church and state.
In 1635, Puritan minister Roger Williams was exiled from the Massachusetts Bay Colony after clashing with colonial authorities over religious uniformity and indigenous land rights. He criticized the mandatory attendance at Puritan services and advocated for fair dealings with Native American tribes. Following his banishment, Williams took refuge with the Narragansett people, learning their language and customs. He subsequently founded Providence Plantations, which evolved into Rhode Island, as a refuge for dissenters. Williams’s pioneering ideas on religious tolerance and church-state separation profoundly influenced American principles of liberty. His legacy endures in Rhode Island’s commitment to freedom of conscience.

Hobart, capital of Tasmania, is founded.
The settlement of Hobart is established, later becoming the capital of Tasmania.
On October 9, 1804, Lieutenant John Bowen founded a British settlement at Risdon Cove on the River Derwent, naming it Hobart Town in honor of Lord Hobart. Originally intended as a military outpost to counter French expansion, it attracted convicts and free settlers seeking new opportunities. The settlement was relocated to Sullivan's Cove later that year due to better water access and soil conditions. By 1821, Hobart had been declared the capital of Van Diemen's Land and evolved into a commercial port. The city's establishment laid the foundations for Tasmania's political and cultural development. Today, Hobart stands as Australia's second oldest capital and a vibrant historic city.

Guayaquil declares independence from Spain.
The city of Guayaquil proclaims its independence from Spanish rule.
On October 9, 1820, residents of Guayaquil rose against Spanish colonial authorities and declared the city's independence, establishing the Free Province of Guayaquil. Key figures such as José Joaquín de Olmedo and José de Antepara led a largely peaceful revolution. Within days, the declaration inspired neighboring regions to join the independence movement, and Simón Bolívar's forces soon entered the city to secure control. Guayaquil's break from Spain was a turning point in the liberation of present-day Ecuador. The event paved the way for the formation of the Republic of Ecuador in 1830. Today, Guayaquil celebrates October 9 as a national holiday commemorating its emancipation.

This move aimed to secure New Zealand’s interests and stabilize governance in the South Pacific. The islands’ residents retained certain local rights while defense and foreign affairs fell under British and New Zealand oversight. The arrangement laid the groundwork for later self-governing status in free association with New Zealand, achieved in 1965.
