Democratic Party (South Korea, 2008)

The party was originally formed as the Uri Party (Yeollin Uri-dang) when loyalists to president Roh Moo-hyun in the Millennium Democratic Party chose to break ranks from other party members who showed lukewarm support for the administration. Some 42 out of 103 lawmakers of the Millennium Democratic Party joined the new party, and 5 lawmakers from the Grand National Party also joined, seeking to complete political reforms. As a result of the 2004 Parliamentary election, the party won an outright majority in the National Assembly by winning 152 of 299 seats. It was the first time in over 40 years that a centre-left party had won a majority in the legislature.

On 18 August 2007, the delegates of the Uri Party decided to disband the party and merge with the newly created liberal party Grand Unified Democratic New Party (대통합민주신당; 大統合民主新黨). After a year, the Grand Unified Democratic New Party merged with the Democratic Party on 17 February 2008, to form the United Democratic Party (Tonghapminjudang).^[1][2] In July 2008, the party changed its name to the Democratic Party.

In local elections 2010, the Democratic Party scored a victory in eight mayoral and gubernatorial posts, including the Inchon mayorship.^[3]

On 16 December 2011, the DP merged with the minor Citizens Unity Party to form the Democratic United Party. The Korean Confederation of Trade Unions also participated in the forming.^[4][5]
