Though generally associated with the Italian Marxist Antonio Gramsci, the idea of hegemony had a crucial history in revolutionary Russia where it was used to conceptualize the dynamics of political and cultural leadership. Drawing on extensive archival research, this study considers the cultural dimensions of hegemony, with particular focus on the role of language in political debates and in scholarship of the period. It is shown that considerations of the relations between the proletariat and peasantry, the cities to the countryside and the metropolitan centre to the colonies of the Russian Empire demanded an intense dialogue between practical politics and theoretical reflection, which led to critical perspectives now assumed to be the achievements of, for instance, sociolinguistics and post-colonial studies.
