Sancho, Count of Provence

Sancho (1161–1223) was the youngest son of Count Ramon Berenguer IV of Barcelona and Queen Petronilla of Aragon. He inherited Provence after the assassination of Ramon Berenguer III in 1181, but Alfonso II deposed him in 1185 for allying with Toulouse and Genoa.

He served as regent of Provence from 1209 and, after Peter II fell at Muret in 1213, as regent of Aragon for the young James I from 1214. His regencies ended in 1218, when papal pressure forced him out for supporting Raymond VI of Toulouse against the Albigensian Crusade, and he died in 1223.
