Casimir III founds the University of Krakow
The Polish king, eager to give his kingdom the trappings of high European civilization, established a studium generale on the model of Bologna.

The Breton mercenary Bertrand du Guesclin defeated a Navarrese-Anglo-Gascon force in Normandy on the day of Charles V's coronation, an auspicious omen for the new king's reign. Du Guesclin used a feigned retreat to draw the enemy into a trap, a tactic he would refine. He would become Constable of France within six years and the architect of a slow, methodical French recovery.
