Glappo

Glappo (or Glappe) (baptized as Charles or Carolus) was the leader of Warmians, one of the Prussian clans, during the Great Prussian Uprising (1260–1274) against the Teutonic Knights.

In 1249 Pope Urban IV had installed the papal legate Jacob Pantaleon to aid the Teutonic Order and after the battle at the Durbe, the pope called for a crusade against the Prussians and sent knights who were on their way against the Tatars back to the crusades against the Prussians. During those crusades and as a result the unbaptized parts of the Prussians began uprisings and Glappo and his men successfully captured Braunsberg. When Glappo ambushed and killed forty people who left the castle to gather firewood and fodder, the Bishop of Warmia decided against trying to defend the town and abandoned it.
