Treaty of Tordesillas
1494 treaty dividing the unclaimed world between Spanish and Portuguese sovereignty
The Treaty of Tordesillas, signed in Tordesillas, Spain, on 7 June 1494, and ratified in Setúbal, Portugal, divided the newly discovered lands outside Europe between the Kingdom of Portugal and the Crown of Castile, along a meridian 370 leagues (c. 2,100 km or 1,300 mi) west of the Cape Verde islands, off the west coast of Africa. That line of demarcation was about halfway between Cape Verde (already Portuguese) and the islands visited by Christopher Columbus on his first voyage (claimed for Castile and León), thought then to be Cipangu and Antillia, but in fact Cuba and Hispaniola; the treaty itself does not mention Cipangu nor Antillia. The lands to the east would belong to Portugal and the lands to the west to Castile, modifying an earlier bull by Pope Alexander VI. The treaty was signed on 7 June 1494, then ratified by Spain on 2 July 1494, by Portugal on 5 September 1494, and by Pope Julius II on 24 January 1506.
