Biography
Born in 1292 to María de Molina and Sancho IV of Castile, spent time during his childhood traveling with his mother in support of his brother Fernando IV (r. 1295-1312). María allotted lands in Galicia to her young son.
Following the deaths of Infantes Juan and Pedro at the Battle of the Vega of Granada, Felipe became a regent for his nephew Alfonso XI of Castile, who was seven years old at the time. Don Juan Manuel and Juan el Tuerto joined Felipe as regents for the young king. Alfonso reached his majority in 1325, and Felipe fades from the historical record at this point. He died soon afterward, in 1327.
