Anarcho-syndicalist organizations were involved in the Spanish Revolution, such as the CNT (Confederación Nacional del Trabajo / National Confederation of Labor), which was long affiliated with the International Workers' Association (AIT). When working with the latter group it was also known as CNT-AIT. Historically, the CNT has also been affiliated with the Federación Anarquista Ibérica.

The most notable aspect of the social revolution was the establishment of a libertarian socialist economy based on coordination through decentralized and horizontal federations of participatory industrial collectives and agrarian communes. In anarchist strongholds like Catalonia, the figure was as high as 75%. Factories were run through worker committees, and agrarian areas became collectivized and run as libertarian socialist communes. Many small businesses like hotels, barber shops, and restaurants were also collectivized and managed by their workers.

Republic (with arms, logistics, military advisers and the NKVD), just as Fascist Italy, Fascist Portugal and Nazi Germany were assisting the opposing Nationalist insurgency. The largest number of volunteers came from France where the French Communist Party had many members, and communist exiles from Italy and Germany. Many Jews were part of the brigades, being particularly numerous among the volunteers coming from the United States, Poland, France, England, and Argentina.
Republican volunteers who were opposed to Stalinism did not join the Brigades but instead enlisted in the separate Popular Front, the POUM (formed from Trotskyist, Bukharinist and other anti-Stalinist groups, which did not separate Spaniards and foreign volunteers -such as George Orwell), or anarcho-syndicalist groups such as the Durruti Column, the IWA and the CNT.

activity related to ISIL and other extremist groups, and are a large strain on the region's economy. The autonomous region is ruled by a coalition which bases its policy ambitions to a large extent on democratic libertarian socialist ideology of democratic confederalism and have been described as pursuing a model of economy that blends co-operative and market enterprise, through a system of local councils in minority, cultural and religious representation. The main military force of the region is the Syrian Democratic Forces, an alliance of Syrian rebel groups formed in 2015. The SDF is led by the Kurdish majority People's Protection Units (YPG).

there are two major social classes, the relationship between these two classes is exploitative, and that this situation can only ultimately be resolved through a social revolution. The two classes are the proletariat (the working class), who make up the majority of the population within society and must work to survive; and the bourgeoisie (the capitalist class), a small minority who derives profit from employing the working class through private ownership of the means of production. According to this analysis, revolution would put the working class in power and in turn establish social ownership of the means of production which is the primary element in the transformation of society towards communism.
After 1917, a number of states were identified as communist: these states espoused Marxism?Leninism or a variation of it. Along with social democracy, communism became the dominant political tendency within the international socialist movement by the 1920s. In practice, the model under which these nominally communist states operated was, in fact, a form of state capitalism or a non-planned administrative-command system and not an actual communist economic model in accordance with most accepted definitions of ?communism? as an economic theory.
