This line of demarcation was about halfway between the Cape Verde islands (already Portuguese) and the islands entered by Christopher Columbus on his first voyage (claimed for Castile and León), named in the treaty as Cipangu and Antilia (Cuba and Hispaniola). </P> <P> The lands to the east would belong to Portugal and the lands to the west to Castile . The treaty was signed by Spain, 2 July 1494, and by Portugal, 5 September 1494 . The other side of the world was divided a few decades later by the Treaty of Zaragoza, 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 . </P>
