Republic of Formosa
The Republic of Formosa (), was a short-lived republic that existed on the island of Taiwan in 1895 between the formal cession of Taiwan by the Qing Dynasty of China to the Empire of Japan by the Treaty of Shimonoseki and it being taken over by Japanese troops. The Republic was proclaimed on 23 May 1895 and extinguished on 21 October, when the Republican capital Tainan was taken over by the Japanese. Though sometimes claimed as the first Asian republic to have been proclaimed, it was predated by the Lanfang Republic in Borneo, established in 1777, as well as by the Republic of Ezo in Japan, established in 1869.
Taiwan
As the Qing dynasty was defeated in the First Sino-Japanese War (1894–1895), Taiwan, along with Penghu and Liaodong Peninsula, were ceded in full sovereignty to the Empire of Japan by the Treaty of Shimonoseki. Inhabitants on Taiwan and Penghu wishing to remain Qing subjects were given a two-year grace period to sell their property and move to mainland China. Very few Taiwanese saw this as feasible. On 25 May 1895, a group of pro-Qing high officials proclaimed the Republic of Formosa to resist impending Japanese rule. Japanese forces entered the capital at Tainan and quelled this resistance on 21 October 1895. Guerrilla fighting continued periodically until about 1902 and ultimately took the lives of 14,000 Taiwanese, or 0.5% of the population. Several subsequent rebellions against the Japanese (the Beipu uprising of 1907, the Tapani incident of 1915, and the Musha incident of 1930) were all unsuccessful but demonstrated opposition to Japanese colonial rule.
