In 1624, after the Dutch occupied Taiwan, they built a fortified castle in Dayuan (present-day Anping District, Tainan City, which was still a small island at the time) and became the center of Dutch rule in Taiwan. In the second year of the castle, the Dutch bought another piece of land from the taiwanese aborigines at the cost of fifteen cotton cloths, and later built a Prominsha City here.
After the Dutch occupied Taiwan, this made the Spaniards in Luzon, the Philippines, nervous, fearing that the Dutch would block the trade routes between Luzon and Chinese mainland and Japan. In 1626, Spain sent a fleet around the easternmost point of the main island of Taiwan, Cape Tri-Sable, into the port of Keelung, occupied sheliao Island (present-day Heping Island), the northernmost point of the main island of Taiwan, and built the city of San Salvador there. In 1628, he occupied Huwei (present-day Tamsui Harbor, Taiwan) and built the city of Santo Domingo (present-day Hongmao City). In this way, the Spaniards effectively occupied Taiwan separately from the Dutch, forming a confrontational situation.
The Spaniards mainly occupied the northern Taiwan region, and in their heyday they established three provinces in northern Taiwan: Tamsui, Doraman (Gongliao District, New Taipei City, Taiwan), and Clam Zainan (Yilan County, Taiwan).
The Spaniards occupied Taiwan for two purposes, one was to preach, and the other was to serve as a trading post. After the Spaniards occupied northern Taiwan, they actively promoted Catholicism and built churches everywhere, and it is said that some indigenous people really believe in Catholicism.
Of course, the most important purpose of the Spaniards was to use northern Taiwan as a trading post. But later the Spaniards found that this stronghold was of little practical use, and China was closing the country to trade at all, and later even Japan was closed to the country and could not trade. The role of this stronghold is decreasing.
Coupled with the fact that the local indigenous people vigorously resisted the Spanish rule and burned down their city of Santo Domingo (present-day Red Mao), the contradictions became more and more intense. Later, when the Spanish rebellion broke out in luzon in the Philippines, the base of Spain in Asia, the Spaniards quickly transferred most of their troops from Taiwan to Luzon to quell the rebellion.
But don't forget, southern Taiwan was a Dutch stronghold, and when they learned that the Spaniards had gone to Luzon to quell the rebellion, then the Spanish defense in northern Taiwan was naturally very weak. So in 1642, the Dutch sent ships north to attack the Spanish stronghold, and because the defenders were not many and weak, they surrendered Kaesong without much resistance.
So, from 1626 to 1642, the Spaniards also colonized northern Taiwan for 16 years.
