Following the death of Harold II at the Battle of Hastings, Edgar the Ætheling is proclaimed King of England by the Witan; he is never crowned, and concedes power to William the Conqueror two months later.

After Harold II's death at the Battle of Hastings, the Witan proclaimed Edgar the Ætheling king of England, though he was never crowned and ceded power to William the Conqueror two months later.
Following the crushing defeat at Hastings, England's Witan council faced a leadership vacuum. They selected Edgar the Ætheling, a teenager of royal bloodline, as king despite his youth and limited military support. Edgar was never formally crowned due to lack of widespread baronial endorsement. Within two months, William of Normandy advanced on London and compelled Edgar to submit peacefully. This transfer averted further civil conflict and cemented William's claim as the first Norman monarch of England. Edgar spent his later years in a subordinate role under the new regime.

Napoleon begins his exile on Saint Helena in the South Atlantic Ocean.

Napoleon Bonaparte commenced his final exile on Saint Helena, ending his dramatic return from Elba and the Hundred Days.
After his defeat at Waterloo in June 1815, Napoleon surrendered to the British and requested asylum aboard their ships. On October 15, 1815, he landed on Saint Helena, a remote volcanic island in the South Atlantic chosen for its isolation. The British governor, Sir Hudson Lowe, imposed strict restrictions on Napoleon's movement and correspondence. Over the next six years, he dictated memoirs and reflected on his career while under constant guard. Napoleon died on the island in 1821, marking the end of an era in European politics and warfare. His exile and death on Saint Helena have since become emblematic of the rise and fall of one of history's greatest military leaders.

President Lluís Companys of Catalonia is executed by the Francoist government.

In 1940, Catalonia's President Lluís Companys was executed by Francoist forces, becoming a symbol of resistance.
On October 15, 1940, Lluís Companys, the former president of Catalonia, was executed by Spain's Francoist government at Montjuïc Castle in Barcelona. Arrested after fleeing to France, he was handed over to Franco's authorities and tried by a military tribunal. Companys' execution was the only instance of a democratically elected European leader executed by a successor regime. His death intensified repression against Catalan culture and autonomy under Franco's dictatorship. Decades later, he was posthumously pardoned, and his legacy endures as a martyr for democracy and regional rights. Companys remains a potent symbol of resistance against authoritarianism in Catalonia and Spain.

New Zealand police conduct the country's first post-9/11 anti-terrorism raids, arresting 17 activists.
On October 15, 2007, New Zealand authorities executed the country's first anti-terrorism operation under new legislation, detaining seventeen individuals suspected of planning violent extremist activities. The raids, coordinated by the Police Special Tactics Group, targeted multiple locations in Auckland.

Although many charges were later dropped or downgraded, the operation reshaped New Zealand’s legal framework for counterterrorism and influenced public discourse on surveillance and community relations.
