Treaty of Tordesillas, divided the newly discovered lands outside Europe between Portugal and Spain along a meridian 370 leagues[note 1] west of the Cape Verde islands (off the west coast of Africa). This line of demarcation was about halfway between the Cape Verde Islands (already Portuguese) and the islands invaded by Christopher Columbus on his first voyage (claimed for Spain), named in the treaty as Cipangu and Antilia (Cuba and Hispaniola).
The lands to the east would belong to Portugal and the lands to the west to Spain. The treaty was ratified by Spain (at the time, the Crowns of Castile and Aragon), 2 July 1494 and by Portugal, 5 September 1494. The other side of the world would be divided a few decades later by the Treaty of Zaragoza or Saragossa, signed on 22 April 1529, which specified the antimeridian to the line of demarcation specified in the Treaty of Tordesillas. Originals of both treaties are kept at the Archivo General de Indias in Spain and at the Arquivo Nacional da Torre do Tombo in Portugal.
