Danmarks Retsforbund (in English known as the Justice Party or Single-Tax Party) was founded in 1919. The party's platform is based upon the principles of U.S. economist Henry George who advocated a single tax on all land. The party was elected to parliament for the first time in 1926, and they were moderately successful in the post-war period and managed to join a governing coalition with the Social Democrats and the Social Liberal Party from the years 1957-60. In 1960 they dropped out of the parliament. However in the 1973 Danish parliamentary election (the so-called Landslide Election) the party won 5 seats in Folketinget, because of their opposition against Danish membership of the European Economic Community. They were represented until 1981 and also in the European Parliament 1978-79 (by Ib Christensen). The 1970s were followed by a dropoff of party support, and the party ceased to run at a national level in 1990, but in 2005 the party ran together with Minoritetspartiet (the Minority Party): this wasn't with any success since the Minority Party only achieved 0.3% of the votes.
