who had most of asia in its sphere of interest after the treaty of saragossa
Treaty of Zaragoza Under the treaty, Portugal gained control of all lands and seas west of the line, including all of Asia and its neighbouring islands so far "discovered", leaving Spain with most of the Pacific Ocean. Although the Philippines was not mentioned in the treaty, Spain implicitly relinquished any claim to it because it was well west of the line. Nevertheless, by 1542, King Charles V had decided to colonise the Philippines, assuming that Portugal would not protest too vigorously because the archipelago had no spices. Although he failed in his attempt, King Philip II succeeded in 1565, establishing the initial Spanish trading post at Manila. As his father had expected, there was little opposition from the Portuguese.
