The Treaty of Zaragoza or Saragossa, also called the Capitulation of Zaragoza or Saragossa, was a peace treaty between Castile and Portugal, signed on 22 April 1529 by King John III of Portugal and the Habsburg Emperor Charles V in the Aragonese city of Zaragoza. The treaty defined the areas of Castilian and Portuguese influence in Asia in order to resolve the "Moluccas issue", which had arisen because both kingdoms claimed the lucrative Spice Islands (now Indonesia's Malukus) for themselves, asserting that they were within their area of influence as specified in 1494 by the Treaty of Tordesillas. The conflict began in 1520, when expeditions from both kingdoms reached the Pacific Ocean, because no agreed meridian of longitude had been established in the far east.
