Taiwan Solidarity Union
In the months following the 2000 presidential election, Lee Teng-hui's supporters established the Taiwan Solidarity Union, which advocated a more radical brand of Taiwan independence than the DPP. For this, Lee was expelled from the KMT and the KMT gradually moved itself to a more conservative and pro-reunificationist position. This permitted the formation of two rival coalitions that have since dominated Taiwanese politics: the Pan-Blue Coalition formed by the KMT, People First Party, and New Party and the Pan-Green Coalition formed by the Democratic Progressive Party and Taiwan Solidarity Union.
