Trotskyist in the context of "Democratic centralism"

The Minneapolis general strike of 1934 grew out of a strike by Teamsters against most of the trucking companies operating in Minneapolis, the major distribution center for the Upper Midwest. The strike began on May 16, 1934 in the Market District (the modern day Warehouse District). The worst single day was Friday, July 20, called "Bloody Friday", when police shot at strikers in a downtown truck battle, killing two and injuring 67. Ensuing violence lasted periodically throughout the summer. The strike was formally ended on August 22.

With a coalition formed by local leaders associated with the Trotskyist Communist League of America, a group that later founded the Socialist Workers Party (United States), the strike paved the way for the organization of over-the-road drivers and the growth of the Teamsters labor union. This strike, along with the 1934 West Coast Longshore Strike and the 1934 Toledo Auto-Lite Strike led by the American Workers Party, were also important catalysts for the rise of industrial unionism in the 1930s, much of which was organized through the Congress of Industrial Organizations.

International Socialist Alternative (ISA) is an international association of Trotskyist political parties.

ISA was founded by sections on one side of a split in the Committee for a Workers' International (CWI).

The Militant tendency, or Militant, was a Trotskyist group in the British Labour Party, organised around the Militant newspaper, which launched in 1964.

In 1975, there was widespread press coverage of a Labour Party report on the infiltration tactics of Militant. Between 1975 and 1980, attempts by Reg Underhill and others in the leadership of the Labour Party to expel Militant were rejected by its National Executive Committee, which appointed a Militant member to the position of National Youth Organiser in 1976 after Militant had won control of the party's youth section, the Labour Party Young Socialists.

The Socialist Workers Party (SWP) is a political party in the United Kingdom. Founded as the Socialist Review Group (SRG) by supporters of Tony Cliff in 1950, it became the International Socialists in 1962 and the SWP in 1977. The party considers itself to be Trotskyist. Cliff and his followers criticised the Soviet Union and its satellites, calling them state capitalist rather than socialist countries.

The SWP has founded several fronts through which they have sought to coordinate and influence leftist action, such as the Anti-Nazi League in the late 1970s. It also formed an alliance with George Galloway and Respect, the dissolution of which in 2007 caused an internal crisis in the SWP. A more serious internal crisis emerged at the beginning of 2013 over allegations of rape and sexual assault made against a leading member of the party. The SWP's handling of these accusations against the individual known as "Comrade Delta", later identified as Martin Smith, led to a significant decline in the party's membership. It also led to a number of formal reviews which resulted in new procedures to support any member who experienced sexual harassment or other forms of oppressive behaviour.

Socialist democracy is a political system that aligns with principles of both socialism and democracy. It includes ideologies such as council communism, social democracy, democratic socialism, and soviet democracy, as well as Marxist democracy like the dictatorship of the proletariat. It was embodied in the Soviet system (1922–1991). It can also denote a system of political party organization like democratic centralism, or a form of democracy espoused by Marxist–Leninist political parties or groups that support one-party states. The Socialist Federal Republic of Yugoslavia (1945–1992) styled itself a socialist democracy, as did the People's Republic of Bulgaria (1946–1990) and the Socialist Republic of Romania (1947–1989).

On the other hand, Trotskyist groups have interpreted socialist democracy to be synonymous with multi-party socialist representation, autonomous union organizations, worker's control of production, internal party democracy and the mass participation of the working masses. Several parties or groups that tend to have a connection to the reunified Fourth International use this label.
