A 4 part document by Alan Woods and Ted Grant. The question of nationalities has always occupied a central position in Marxist theory. In particular, the writings of Lenin deal with this important issue in great detail. It is true to say that, without a correct appraisal of the national question, the Bolsheviks would never have succeeded in coming to power in 1917. This document reviews the rich Marxist literature on this issue and applies it to today's conditions.
