1130 CE
A year marked by the coronation of Roger II as King of Sicily, uniting the Norman territories of southern Italy and Sicily into a powerful Mediterranean kingdom, and the beginning of a papal schism that divided the Western Church.
Geopolitics & Diplomacy
- Roger II was crowned King of Sicily on Christmas Day in Palermo, unifying the Norman domains of Sicily, Calabria, and Apulia into a single kingdom that would become one of the wealthiest and most culturally diverse states in medieval Europe.
- A contested papal election produced two rival popes, Innocent II and Anacletus II, splitting the Church and European political allegiances for the next eight years.
- Roger II supported Anacletus II, who had granted him the royal title, while most of Europe recognized Innocent II, creating a complex web of political and religious loyalties.
Economy & Finance
- The Kingdom of Sicily under Roger II benefited from its position at the crossroads of Mediterranean trade, with Norman, Arab, Greek, and Jewish communities contributing to a thriving multicultural economy.
Climate & Environment
- Atmospheric carbon dioxide concentration was approximately 275 parts per million, as later confirmed by ice core analysis.
Culture & Society
- The Norman court in Palermo became renowned for its blending of Latin Christian, Byzantine Greek, and Arab Islamic cultural traditions in art, architecture, and governance.
- The estimated world population was approximately 333 million.
