These texts by Samir Amin have been selected for the purpose of encouraging readers to learn more about his work to trace the historical trajectory of capitalism, which has consistently produced polarization at the global level. Thus the dominated peripheries cannot hope to catch up with the social organization prevailing in the dominant centres and the impossibility of global capitalism becoming stabilized in its peripheries has resulted in the long decline of capitalism, coinciding with successive waves of active involvement by the peoples of the South to shape a new world, potentially embarking on the long journey to socialism. Amin presents this major conflict of the 20th century and identifies the new challenges that the system now faces in the 21st century. His analysis is conducted in terms of historical materialism and should be a useful tool for activists struggling for socialism. Their progress is linked to the emancipation of the Asian, African and Latin American peoples.
