Alexios Komnenos seizes Byzantine throne
After a sharp revolt supported by his mother and brother, the young general entered Constantinople and had himself crowned emperor. Over thirty-seven years Alexios I would stabilize Byzantine finances, drive back Normans and Pechenegs, and by inviting Western help inadvertently set in motion the First Crusade. His daughter Anna Komnene would later chronicle his reign in the Alexiad, one of the great works of medieval historiography.
Song Dynasty Develops Early Paper Currency Systems
In Sichuan province, where heavy iron coins made commerce physically exhausting, merchants and provincial officials refined the jiaozi - government-issued paper certificates backed by coin reserves. These were not mere promissory notes but true currency: printed in standard denominations, enforced by law, and accepted for tax payments. Song China was inventing fiat money, a financial technology so abstract that Europe would need another six centuries to discover it independently.
Ly Dynasty Vietnam Repels Champa Incursion
Champa raiders struck northward into Dai Viet territory, testing the young dynasty's southern defenses. The Vietnamese response was swift and decisive: Ly generals pushed the Cham forces back across the frontier and launched punitive raids that reminded Champa's kings of the military lessons taught at Nhu Nguyet. Vietnam was fighting on two fronts - Song China to the north, Champa to the south - and holding both.
Battle of Dyrrachium
Robert Guiscard's Normans, having crossed the Adriatic, crushed Alexios I's relief army outside the walls of Dyrrachium. The Varangian Guard was annihilated in the fight. Byzantine power in the western Balkans collapsed. Only the recall of Guiscard to Italy by his pope-versus-emperor crisis saved Alexios from a march east. The Varangian losses were so severe that Alexios rebuilt the unit with Anglo-Saxon refugees from Norman England.
