La Concordia de 1474

The Concordia of 1474 was a treaty between Portugal and Castile (later Spain) aimed at resolving conflicts over territorial claims in the New World, especially in the Americas. It established guidelines for dividing lands and addressing disputes, promoting cooperation and preventing war between the two kingdoms. This agreement contributed to defining spheres of influence before the Treaty of Tordesillas later formalized more precise dividing lines. Overall, the Concordia was an important step in early European efforts to peacefully manage their overseas ambitions and territorial claims.
