The Democratic Progressive Party (Chinese: 民主進步黨; Pinyin: Mínzhǔ jìnbù dǎng) is the largest party of the pan-Green coalition. It was born out of the anti-KMT Tangwai movement, officially being established in September 1986. The DPP has had two of its members become President of the Republic of China: Chen Shui-bian in 2000-2008 and incumbent Tsai Ing-wen from 2016.
The party was originally constituted by various political groups, the only common thread between whom was their dislike of the KMT. These included liberals, Taiwanese nationalists, environmentalists, feminists, and several others.
With the rapid democratisation by the end of Chiang Ching-kuo's reign and under Lee Teng-hui essentially made the DPP lose its platform, which meant it increased emphasis on ideological issues, such as identity politics and the question of Taiwan independence.
