In 1989, the "Berlin wall" fell to the east, the feeling of being in the presence of the final triumph of Capitalism permeated in the collective consciousness of the Western world. In that context, the particular Venezuelan situation, expressed in the radicalization of the "Bolivarian Revolution", takes up the debate on Socialism; not nostalgically of the defeated Socialism in Eastern Europe, but from the need to think and build a "new" idea: "The Socialism of XXI Century". Analysing the most frequent postulates among those who defend the new Socialism, this article seeks to approximate a theoretical synthesis that can contribute in the search for a definition composed of affirmative statements. To meet this goal, the notions that are defining in the "Socialism of XXI Century" (the denial of nationalization, worker self-management, plurality of ownership, participatory democracy, etc.) are listed, a synthesis is performed, and the relevant conclusions are formulated, which they maintain, that, the "Socialism of the XXI Century", as a theoretical approach, is far from representing a real revolutionary theory. © 2019 Institute of Latin American Studies, Russian Academy of Sciences.
