Sundiata founds the Mali Empire at Kirina
At the Battle of Kirina on the upper Niger, the exiled Mande prince Sundiata Keita broke the sorcerer-king Sumanguru of Sosso and assembled the scattered clans into the Mali Empire. His gold and griots would reshape West Africa's political and literary geography. The Kouroukan Fouga, a charter of governance attributed to Sundiata, organized the empire's clans and trade guilds for generations to come.
Mongols hold great kurultai at Karakorum
Ogedei Khan, Genghis's successor, gathered the princes of the house of Borjigin at the new Mongol capital. They authorized simultaneous campaigns against Song China, the Middle East, and the kingdoms of eastern Europe. Karakorum's walls rose to house the spoils. The decision to attack on three fronts simultaneously demonstrated a logistical ambition that no other medieval power could have attempted or sustained.
Frederick II issues the Statute in Favour of Princes
At Mainz, the emperor granted the German princes sweeping rights over coinage, tolls, and justice in their lands. The statute ratified the decentralization of the empire and ensured that Germany would enter the modern era as a patchwork rather than a nation state. Frederick traded central authority for princely support in his Italian wars, a bargain that would haunt German politics for six centuries.
Chan Chan expands its adobe wards
The Chimu capital on Peru's north coast grew into the largest pre-Columbian city in the Americas, with its ten royal ciudadelas, each built for a dead king, arranged across twenty square kilometers of adobe walls. Its artisans produced some of the finest Andean metalwork of any era. Gold and silver vessels, hammered into impossibly thin sheets and decorated with maritime motifs, filled the royal tombs.
