Sancho IV of Castile

Sancho IV "the Brave" (1257/58 - April 25, 1295) was a king of Castile and León (1284 - 1295). He was the son of Alfonso X. His elder brother, Ferdinand de la Cerda, died in November 1275, and in 1282 Sancho assembled a coalition of nobles to declare for him against Ferdinand's son Alfonso, then took control of the kingdom when Alfonso X died in 1284.

In 1291, Sancho led an expedition that captured the port of Tarifa from the Moors.

Just before succumbing to a fatal illness in 1295, he appointed his queen Maria de Molina to act as regent for his son Ferdinand. He died in Toledo.
