"Dutch Formosa" refers to the period when the Dutch East India Company established a colony on the island of Taiwan, known as Formosa, from 1624 to 1662. The Dutch aimed to control trade routes and establish a foothold in East Asia. They built Fort Zeelandia in Tainan, which served as the center of their operations and facilitated trade with local indigenous peoples and other Asian markets. During their rule, the Dutch introduced agricultural practices and promoted the cultivation of rice and sugarcane. They also engaged in trade with the Chinese and Japanese, significantly impacting the island's economy. However, their control ended when the Ming loyalist Koxinga expelled them in 1662, leading to the establishment of a new regime on the island.
