Unabhängige Sozialdemokratische Partei Deutschlands

The Unabhängige Sozialdemokratische Partei Deutschlands (English: Independent Sozial Democratic Party of Germany), often abbreviated as USPD, was a socialistic party with authoritarian tendencies. The party was founded in 1875 by David Blaustein, who left the PKW in the process, and was mostly dead by 1880. In 1875, it was engaged in coalition talks with the DkP and PVP, making it clear to its followers that the USPD was willing to give up their socialist ideals to be included into a government. As a result, the party lost a considerable amount of its members and was completely voted out of the Reichstag in the 1880 elections.
