Treaty of Zaragoza

The Treaty of Zaragoza, or Treaty of Saragossa, also referred to as the Capitulation of Zaragoza, was a peace treaty between the Spanish Crown and Portugal, signed on 22 April 1529 by King John III and the Emperor Charles V in the Aragonese city of Zaragoza. 

The treaty defined the areas of Castilian (Spanish) and Portuguese influence in Asia to resolve the "Moluccas issue", when both kingdoms claimed the Moluccas islands for themselves, considering it within their exploration area established by the Treaty of Tordesillas in 1494. 

The conflict sprang in 1520, when the expeditions of both kingdoms reached the Pacific Ocean, since there was not a set limit to the east.
