Ibn Ezra, Judah

Son of Joseph ibn Ezra of Granada; Spanish state official of the twelfth century. He was raised by Alfonso VII. of Castileto the position of commander of the frontier fort of Calatrava, to the dignity of "nasi" (prince), and, a few years later, to the post of majordomo of the royal household. Judah used his position and wealth to benefit his coreligionists, who were persecuted by the victorious Almohades. With the permission of Alfonso, Judah also vigorously combated Karaism, which was gaining ground in Castile, and wrote in refutation of its arguments.
