The Battle of Toro was a royal battle from the War of the Castilian Succession, fought on 1 March 1476, near the city of Toro, between the Castilian-Aragonese troops of the Catholic Monarchs and the Portuguese-Castilian forces of Afonso V and Prince John of Portugal. The battle had an inconclusive military outcome, as both sides claimed victory: the Castilian right wing was defeated by the forces under Prince John who possessed the battlefield, but the troops of Afonso V were beaten by the Castilian left-centre led by the Duke of Alba and Cardinal Mendoza.
