The Treaty of Zamora (5 October 1143) recognized Portugal as a kingdom with its own monarch by the Kingdom of León. Based on the terms of the accord, King Alfonso VII of León recognized the Kingdom of Portugal in the presence of his cousin King Afonso I of Portugal, witnessed by the papal representative, Cardinal Guido de Vico, at the Cathedral of Zamora. Both kings promised durable peace between their kingdoms.[1] By this treaty, Afonso I of Portugal also recognized the suzerainty of the Pope.
