This volume explores for the first time the complex interrelationships between labour, nationalist movements and ethnicity during the Age of Imperialism 1870-1939.. "Two of the most debated contemporary issues focus on the decline of labour, particularly socialist ideologies, and the rise of nationalism. It is sometimes assumed that the demise of one led or caused the triumph of the other. Indeed it is often thought that labour as an internationalist movement underestimated and misunderstood the power of nationalism. This book, by linking these historical phenomena, sets this debate in a more accurate historical context.
