Right-wing politics
Although the right-wing originated with traditional conservatives, monarchists, and reactionaries, the term extreme right-wing has also been applied to movements including fascism, Nazism, and racial supremacy. From the 1830s to the 1880s, there was a shift in the Western world of social class structure and the economy, moving away from nobility and aristocracy towards capitalism. This general economic shift toward capitalism affected centre-right movements such as the British Conservative Party, which responded by becoming supportive of capitalism. In the United States, the Right includes both economic and social conservatives. In Europe, economic conservatives are usually considered liberal and the Right includes nationalists, nativist opposition to immigration, religious conservatives, and historically a significant presence of right-wing movements with anti-capitalist sentiments including conservatives and fascists who opposed what they saw as the selfishness and excessive materialism inherent in contemporary capitalism.
Left communism
Left communism is the range of Marxist viewpoints held by the left-wing of communism which criticizes the political ideas and practices espoused—particularly following the series of revolutions which brought World War I to an end—by Bolsheviks and by social democrats. Left communists assert positions which they regard as more authentically Marxist and proletarian than the views of Marxism–Leninism espoused by the Communist International after its first congress (March 1919) and during its second congress (July–August 1920).
