Conservatism
According to Alan Ware, Belgium, Denmark, Finland, France, Greece, Iceland, Luxembourg, Netherlands, Norway, Sweden, Switzerland and the United Kingdom retained viable conservative parties into the 1980s. Ware said that Australia, Germany, Israel, Italy, Japan, Malta, New Zealand, Spain and the United States had no conservative parties, although they had either Christian democrats or liberals as major right-wing parties. Canada, Ireland and Portugal had right-wing political parties that defied categorization: the Progressive Conservative Party of Canada; Fianna Fáil, Fine Gael and Progressive Democrats in Ireland; and the Social Democratic Party of Portugal. Since then, the Swiss People's Party has moved to the extreme right and is no longer considered to be conservative.
Libertarian socialism
Left communism is the range of communist viewpoints held by the communist left, which criticizes the political ideas of the Bolsheviks at certain periods, from a position that is asserted to be more authentically Marxist and proletarian than the views of Leninism held by the Communist International after its first and during its second congress. Left communists see themselves to the left of Leninists (whom they tend to see as "left of capital", not socialists), anarchists (some of whom they consider internationalist socialists) as well as some other revolutionary socialist tendencies (for example De Leonists, who they tend to see as being internationalist socialists only in limited instances). Although she lived before left communism became a distinct tendency, Rosa Luxemburg has heavily influenced most left communists, both politically and theoretically. Proponents of left communism have included Amadeo Bordiga, Herman Gorter, Anton Pannekoek, Otto Rühle, Karl Korsch, Sylvia Pankhurst and Paul Mattick.
