Republic of Formosa
The Republic of Formosa survived for only five months. The Japanese landed near Keelung on the northern coast of Taiwan on 29 May 1895, and in a five-month campaign swept southwards to Tainan. During the night of 4 June, on the news that the Japanese had captured Keelung, President T'ang and General Chiu fled to Tamsui, and from there sailed for the mainland on the evening of 6 June. The Japanese entered Taipei shortly afterwards.
Dutch Empire
In 1661, amidst the Qing conquest of China, Ming general Koxinga led a fleet to invade Formosa. The Dutch defense, led by governor Frederick Coyett, held out for nine months. However, after Koxinga defeated Dutch reinforcements from Java, Coyett surrendered Formosa. The Dutch would never rule Formosa again.
