St. Francis Xavier was born in Navarre on April 7, 1506, the youngest of the five children of Juan de Jassa and Maria de Azpilcueta. Xavier’s family was loyal to the rulers of Navarre. Castile had annexed this territory, after much fighting, and in 1521 Navarre rebelled against Castile. Many of Francis’ relatives were involved in this fight, as was Ignatius of Loyola; however, Ignatius was fighting on the side of Castile, as that was where his family’s loyalty lay. This battle was the one in which Ignatuis’ leg was injured.
