‘To think of emancipation’, a century after the global revolutionary wave that began in 1917, is to question the very term emancipation. Who is the subject of this emancipation and who emancipates who, in a struggle that is anything but an ideological game between four walls. This emancipation has its source in the working class (manual and intellectual). It cannot be assimilated to a “struggle of the people”, whose “Cause” would be national and patriotic. ‘To think of emancipation’ in  is to look back at the great proletarian revolutionary insurrections in Russia and Germany and draw lessons from them at the beginning of the third millennium. In doing so, the revolution in Germany from 1918 to 1921 is an essential milestone, since it raised the question of the forms of organization of any revolutionary class struggle: workers councils, workers’ unions, revolutionary factory organizations, factory committees or action committees. Like the Russian Revolution, it raised – albeit to a lesser degree, in the absence of a real takeover of power – the question of socialization of the means of production, and therefore of the abolition of the capitalist system based on profit.
