The party was formed when the conservative-dominated National Assembly voted to impeach then President Roh Moo-hyun, loyalists and pro-Roh faction 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 MillenniumDemocratic Party joined the new party, and 5 lawmakers from the conservative Grand National Party also joined, seeking to complete political reforms. The Uri Party won a sweeping victory in the 2004 Parliamentary election, winning 152 of 299 seats. It was the first time that a liberal party had won a majority in 41 years.
Policywise, the Uri Party emphasized increased spending on social services for the low-income population while de-emphasizing economic growth. It was conciliatory towards North Korea while moving away from the traditional military alliance with the U.S. and Japan. Even after North Korea had continued testing explosive devices, Uri Party members have for continued aid to North Korea, leading to heavy criticism from conservative parties and accusations of harboring Communist sympathizers. The Uri Party placed most of the blame for the crisis on the hard-line policies of the United States toward North Korea.
Significant events
The party came to international attention when their members physically blocked the speaker's chair in the National Assembly in a failed attempt to prevent the impeachment vote on President Roh on March 12, 2004. The impeachment was influenced to the Assembly elections, which the party won a majority. On August 19, 2004, the party suffered an embarrassing setback when party chairman Shin Ki-nam resigned following revelations by a national investigation that his father had worked for the Japanese military police during the Japanese occupation. The investigation, initiated on the 56th anniversary of Liberation Day by President Roh, was a part of a national campaign to shed light on the activity of collaborators during the Japanese occupation. The campaign was vocally supported by Shin and backed by the Uri Party. The party's popularity has decreased considerably after the 2004 election because of internal strife and scandals related to the President, who had admitted to feeling "incompetent" and unfit for the job. The Uri party failed to secure a single seat out of six electoral districts in the by-election held on April 30, 2005, losing its majority status in the National Assembly. Despite they lost the majority status, they relied support from the centrist Democratic Party and left-wing Democratic Labor Party, which the liberals maintained majority in the National Assembly. Prior to the Uri Party's devastating defeat in regional elections held on May 31, 2006, Chung apologized for the party's "self-righteous attitude and inadequacy". The party failed to win in all but one area, while the opposition Grand National Party took 12 of the 16 key regional posts in the election. The Uri Party even lost in Daejeon, a city long considered a secure ruling-party stronghold.
On August 18, 2007, the delegates of the Uri Party decided to merge with the newly created liberal party called "the United New Democratic Party" to form the Democratic Party.
