Henry initially sought to recover territory lost to Castile by assisting the revolt of Philip, brother of Alfonso X of Castile, in 1270, but eventually declined, preferring to establish an alliance with Castile through the marriage of his son Theobald to Violant of Castile, daughter of Alfonso X. This failed with the death of the young Theobald after he fell from a battlement at the castle of Estella in 1273.
