The struggle lasted for a period of five years, costing a great number of lives, especially on the aboriginal side, which lacked sufficient means to defend itself against the armies sent by the Catholic Monarchs. Even so, resistance was fierce. The end of the conquest came in 1483, with the incorporation of the island into the Crown of Castile by Pedro de Vera, who managed to subjugate the natives of Gáldar in the northwest of the island.
