In 1919, Bolshevik Russia and its followers formed the Communist International, also known as the Comintern, to oversee the global communist movement. From the very beginning, the Comintern committed itself to ending world imperialism, supporting colonial liberation, and promoting racial equality.

Coinciding with the centenary of the Comintern's founding, Left Transnationalism highlights the different approaches interwar communists took in responding to these issues. Bringing together leading and emerging scholars on the Communist International, individual communist parties, and national and colonial questions, this collection moves beyond the hyperpoliticized scholarship of the Cold War era and re-energizes the field. Contributors focus on transnational diasporic and cultural networks, comparative studies of key debates on race and anti-colonialism, the internationalizing impulse of the movement, and the evolution of communist platforms through transnational exchange. Essays further emphasize the involvement of communist and socialist parties across Canada, Australia, India, China, Japan, Southeast Asia, Latin America, South Africa, and Europe.

Highlighting the active discussions on nationality, race, and imperialism that took place in Comintern circles, Left Transnationalism demonstrates that this organization - as well as communism in general - was, especially in the years before 1935, far more heterogeneous, creative, and unpredictable than the rubber stamp of the Soviet Union described in conventional historiography.
