The Treaty of Zaragoza stated the continuation of the meridian of Tordesillas in the opposite hemisphere, 297.5
marine leagues ( about 1,487
kilometers / 892
miles ) east of the Maluku.
The Philippines stood on the Spanish side, while the Maluku Islands were provided by Spain to Portugal over the payment of 350,000 gold ducats[9]. The treaty had also a safeguard stating that, if at any time the emperor wished to restore the deal, the sale would be undone and each "will have the right and the action as that is now." Obviously, this never happened, because the emperor needed desperately the Portuguese money to finance the
war of the League of Cognac against its arch-rival
Francis I of France.
The Portuguese delegation sent by king João III included, among others, António de Azevedo Coutinho, Diogo Lopes de Sequeira, Lopo Homem and Simão Fernandes. Plenipotentiaries were, from Portugal, António Azevedo Coutinho and from Spain Count Mercurio Gâtine, Garcia de Loyosa
Bishop of Osma, and Garcia de Padilla, commander of Calatrava.
Posterior measurements proved that, according to the exact anti-meridian of Tordesillas, the Maluku and also the Philippines were in the Portuguese hemisphere.
