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.
Natalia Republic
The Natalia Republic was a short-lived Boer republic on the coast of Southern Africa, established in 1839 by Voortrekkers shortly after the Battle of Blood River. The area was ceded by the Zulu king Dingane to Piet Retief and his party in 1838 and stretched from the Tugela River to present day Port St. Johns. It was previously named "Natália" by Portuguese sailors. The republic was annexed by Britain in 1843 to form the Colony of Natal. After the British annexation of the Natalia Republic, most local Voortrekkers trekked north into "Transorangia", later known as the Orange Free State, and the Transvaal.
