Sancho IV the Brave was the King of Castile, León and Galicia from 1284 to his death. He was the second son of Alfonso X and Yolanda, daughter of James I of Aragon.
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.
Sancho was recognized and supported by the majority of the nobility and the cities, but a sizable minority opposed him throughout his reign and worked for the heirs of Ferdinand de la Cerda. One of the leaders of the opposition was his brother John, who united to his cause the lord of Biscay, Lope Díaz III de Haro. Sancho responded by executing the Lord of Biscay and incarcerating his brother. According to the chroniclers, he cemented his hold on power by executing 4,000 other followers of Infante Alfonso, son of Ferdinand de la Cerda, in Badajoz. He executed 400 more in Talavera and more in Ávila and Toledo.
Upon dispensing with this opposition, Sancho pardoned his brother, who was released. John bided his time before fomenting revolt again: the conflict over Tarifa. He called in the aid of the Marinids of Morocco and besieged Guzmán the Good in his castle (1291). Tarifa was faithfully defended until Sancho could rescue it and the Marinids retreated to Morocco.
Just before succumbing to a fatal illness, he appointed his queen, María de Molina, to act as regent for his nine year-old son, Ferdinand IV. He died in 1295 in Toledo.
Sancho married Maria de Molina in 1282 and they had the following children:
Isabella (1283–1328). Married first James II of Aragon and secondly John III, Duke of Brittany.
Ferdinand IV (1285–1312).
Alfonso (1286–1291)

Philip (1292–1327). Married his cousin Margarita de la Cerda, daughter of Alfonso de la Cerda (1270-1333).
