Louis, son of Charlemagne, received the imperial crown from the pope, continuing the Carolingian dynasty's claim to a revived Western Roman imperial title first established by his father.

Portugal gains recognition as an independent kingdom through the Treaty of Zamora.

Following decades of struggle to establish Portugal as independent from the Kingdom of Leon, the Treaty of Zamora formally recognized Portuguese sovereignty under Afonso Henriques, who became the country's first king.

A military-led revolution overthrew Portugal's centuries-old monarchy, forcing King Manuel II into exile and establishing the First Portuguese Republic amid widespread public discontent with the monarchy's declining authority and financial troubles.

A Chilean opposition coalition defeats Augusto Pinochet in a national plebiscite on his continued rule.

In a stunning upset that defied Pinochet's expectations, Chilean voters rejected the military dictator's bid to extend his rule for another eight years in a national plebiscite, a decisive step toward restoring democratic governance after 15 years of authoritarian rule following the 1973 coup.
