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.
Republic of West Florida
The boundaries of the Republic of West Florida included all territory south of parallel 31°N, east of the Mississippi River, and north of the waterway formed by the Iberville River, Amite River, Lake Maurepas, Pass Manchac, Lake Pontchartrain, and the Rigolets. The Pearl River, with its branch that flowed into the Rigolets, formed the eastern boundary of the republic. A military expedition from the republic attempted but failed to capture the Spanish outpost at Mobile, which was situated between the Pearl and the Perdido River, farther to the east. Despite its name, none of the Republic of West Florida was within the borders of the present-day state of Florida, but rather entirely within the present borders of Louisiana.
