The Social Democratic Party of Ukraine (united) (), is a Ukrainian political party that was originally established as the Social Democratic Party of Ukraine. At the 1998 and 2002 parliamentary elections it won parliamentary seats, but has since then failed to win any seats. When in the Verkhovna Rada the party was influential, but since the Orange Revolution (of late 2004) it has been marginalized. History Social Democratic Party of Ukraine The Social Democratic Party of Ukraine () was founded in May 1990. Unlike the originally-united SD, the Social Democratic refused to follow democratic socialism and was against the Ukrainian federalist movement. The party joined the People's Movement of Ukraine, which already had some of its members in Verkhovna Rada. During the 1991 presidential elections, it supported Viacheslav Chornovil. In May 1992, Yuriy Zbitnyev was elected a head of the party replacing, Oleksandr Suhonyako. Suhonyako, who wanted the party to follow social liberalism policies left the party with his supporters. In the spring of 1993, two parties were merged: the Social Democratic Party of Ukraine and the United Social Democratic Party of Ukraine (led by Yuriy Buzduhan) and were registered as a single party, called the Social Democratic Party of Ukraine. Buzduhan was head of the new party. Before the next parliamentary elections, the new party was to be also merged with the Party of Democratic Revival of Ukraine, but such agreements fell through, and the parties ran independently. The party elected two People's Deputies in the 1994 Ukrainian parliamentary election, Buzduhan and Hryhoriy Ryhachov. Following the 1994 parliamentary election, the party split into two factions. The first was led by Buzduhan, and was re-registered as the Social Democratic Party of Ukraine. The other faction, led by Yuriy Zbitnyev also wanted to be registered as SDPU, but was denied registration under such name. Social Democratic Party of Ukraine (united) In 1995, a new merger was registered by Ministry of Justice of Ukraine where the Zbitnyev's faction of former SDPU merged with Party of Human Rights () of Vasyl Onopenko and Ukrainian Party of Justice () of Mykhailo Hrechka to form the Social Democratic Party of Ukraine (united). The head of the new party was Minister of Justice Vasyl Onopenko, while his deputies were Viktor Medvedchuk, Yuriy Zbitnyev and Mykhailo Hrechka. The documents of the new party stated that it was the successor of SDPU, Party of Human Rights and Ukrainian
