The Democratic Justice Party (DJP) was the ruling party of South Korea from 1980 to 1998. It was formed in 1980 as the Democratic Republican Party and was the political vehicle for Chun Doo-hwan.
When 1979, Park Chung-hee's assassination, Chun Doo-hwan of the party created it the 'Democratic Justice Party' in 1980. Even though a less authoritarian constitution was enacted that year, the political system was rigged heavily in favor of the DJP. The situation changed in 1987, when DJP presidential candidate Roh Tae Woo promised that year's election would be free and democratic. In 1990, the DJP merged with Kim Young Sam's Reunification Democratic Party and Kim Jong-pil's New Democratic Republican Party to form the Democratic Liberal Party.
