Mendoza, Pedro González de

Mendoza, Pedro González de (pā`thrō gōnthä`lĕth dā māndō`thä), 1428–95, Spanish cardinal and archbishop of Toledo. He was the son of the poet Iñigo López de Mendoza, marqués de Santillana. He supported Henry IV of Castile in his struggles against the nobles and later sided with Isabella I against Juana la Beltraneja. More a soldier than a prelate, he fought in the battle of Toro (1476) against the Portuguese and later took part in the conquest of Granada. He also cultivated literature and wrote religious and political works.
