As the membership of a communist party was to be limited to active
cadres in Lenin's theory, there was a need for networks of separate organizations to mobilize mass support for the party. Typically, communist parties built up various
front organizations whose membership was often open to non-communists. In many countries, the single most important front organization of the communist parties was its
youth wing. During the time of the
Communist International, the youth leagues were explicit communist organizations, using the name '
Young Communist League'. Later the youth league concept was broadened in many countries, and names like 'Democratic Youth League' were adopted. Some
trade unions and students', women's, peasants', and cultural organizations have been connected to communist parties. Traditionally, these mass organizations were often politically subordinated to the political leadership of the party. After the fall of communist party regimes in the 1990s, mass organizations sometimes outlived their communist party founders. in
Hanoi At the international level, the Communist International organized various international front organizations (linking national mass organizations with each other), such as the
Young Communist International,
Profintern,
Krestintern,
International Red Aid,
Sportintern, etc. Many of these organizations were disbanded after the dissolution of the Communist International. After the
Second World War new international coordination bodies were created, such as the
World Federation of Democratic Youth,
International Union of Students,
World Federation of Trade Unions,
Women's International Democratic Federation and the
World Peace Council. The Soviet Union unified many of the Comintern's original goals in the
Eastern Bloc under the aegis of a new organization, the
Cominform. Historically, in countries where communist parties were struggling to attain state power, the formation of wartime alliances with non-communist parties and wartime groups was enacted (such as the
National Liberation Front of Albania). Upon attaining state power these Fronts were often transformed into nominal (and usually electoral) "National" or "Fatherland" Fronts in which non-communist parties and organizations were given token representation (a practice known as
Blockpartei), the most popular examples of these being the
National Front of East Germany (as a historical example) and the
North Korean Reunification Front (as a modern-day example). Other times the formation of such Fronts was undertaken without the participation of other parties, such as the
Socialist Alliance of Working People of Yugoslavia and the
National Front of Afghanistan, though the purpose was the same: to promote the communist party line to generally non-communist audiences and to mobilize them to carry out tasks within the country under the aegis of the Front. Recent scholarship has developed the comparative political study of global communist parties by examining similarities and differences across historical geographies. In particular, the rise of revolutionary parties, their spread internationally, the appearance of charismatic revolutionary leaders and their ultimate demise during the decline and fall of communist parties worldwide have all been the subject of investigation. == Naming ==
