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.
Ta-Chia-hsi revolt
The Ta Chia-Hsi Revolt (; also Taikasei revolt) of 1731-32 was a major aboriginal revolt on Formosa, which saw the Taokas tribe take up arms against the Qing authorities following a series of issues with the corvee labor policy. The Taokas swept southward and were joined by other plains aboriginal groups, stopping to lay siege to the walled city of Changhua. The revolt ended following the Qing enlisting the help of the An-li tribe and Green Standard troops from the south.
