Background and detail
Background. Following Columbus's voyages, Portugal claimed the islands under the 1479 Treaty of Alcáçovas and the 1481 papal bull Aeterni regis. Spain rejected these claims, asserting ownership of the discovered islands and warning Portugal against interference.
Terms. The treaty established a meridian 370 leagues west of the Cape Verde islands. Lands east of the line belonged to Portugal, while lands west belonged to Castile. This arrangement modified an earlier bull issued by Pope Alexander VI.
Ratification. After signing on 7 June 1494, the treaty was ratified by Spain on 2 July 1494 and by Portugal on 5 September 1494. Pope Julius II provided further ratification on 24 January 1506, solidifying the agreement.
