Important Events That Happened On December 15 In History

1025 – Constantine VIII’s Solo Reign Begins
After 63 years serving as co-emperor—first with his father and then his brother—Constantine VIII became the sole ruler of the Byzantine Empire. His long-awaited solo reign, however, was marked by indifference to governance and a focus on pleasure, weakening the state.
1161 – A Jin Emperor Falls to Assassins
