Definition of "dangwai"

The evolution of Taiwan’s democracy — starting with the dangwai (黨外, “outside the party”) political movement during the 1970s and 1980s, the formation of the Democratic Progressive Party (DPP) in 1986 and the party’s ascent to government in 2000 — was a long and thorny path involving contributions by many democracy advocates.

During the latter part of Taiwan's authoritarian period, social protest movements arose that complemented the periodic efforts of the political opposition- the dangwai-to open the political system. One of the most prominent movements occurred in the town of Lukang in Changhua County in 1986.
