Ferdinand III of Castille
13th-century saint and king of Castile, Leon and Galicia
Feast: 30 May (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Ferdinand, King of Castile from 1217 and of León from 1230, cousin of St Louis IX, chose wise counsellors, saw to strict justice and would not overtax his people, fearing, he said, the curse of one poor woman more than an army of Saracens.
He married Beatrice of Swabia and had seven children. His highest aims were spreading the Faith and freeing Spain from Muslim rule. A member of the Third Order of St Francis, he died at Seville on 30 May 1252; many miracles took place at his tomb.
The miracles
The Catholic Encyclopedia notes many miracles at his tomb but does not describe those approved for his canonisation.
Why that counted as sanctity
A just king who feared wronging the poor more than any enemy.
