The National Flag of Republic of Formosa was used as flag and emblem of the Republic of Formosa, which was founded in Taiwan and existed from May 23 to October in 1895. Due to its design of a blue ground and a yellow tiger, it was also called the Blue Ground Yellow Tiger Flag, or simply the Yellow Tiger Flag. On the same day the flag began its usage, Tang Jingsong (唐景崧) announced the “Declaration of Independence of the Republic of Formosa.”
