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.
Zamboanga City
Before the end of the 19th century, the Republic of Zamboanga was established right after when the Zamboangueño revolutionary forces defeated the last Spanish Government in Zamboanga and when Fort Pilar was turned over to General Vicente Álvarez, the first genuinely elected president who ruled the República de Zamboanga from 18 May 1899 until November 1899. The Republic of Zamboanga continued to exist until 1903 with Isidoro Midel as the 2nd President under a puppet government of the United States of America, and who was succeeded by Mariano Arquiza.
