An agreement was reached in 1494, with the Treaty of Tordesillas that divided the world between the two powers. In this treaty the Portuguese received everything outside Europe east of a line that ran 370 leagues west of the Cape Verde islands (already Portuguese), and the islands discovered by Christopher Columbus on his first voyage (claimed for Castile), named in the treaty as Cipangu and Antilia (Cuba and Hispaniola). This gave them control over Africa, Asia and eastern South America (Brazil). The Spanish (Castile) received everything west of this line. At the time of negotiation, the treaty split the known world of Atlantic islands roughly in half, with the dividing line about halfway between Portuguese Cape Verde and the Spanish discoveries in the Caribbean.
