How did thousands of Indians who migrated to the Pacific Coast of North America during the early twentieth century come to forge an anticolonial movement that British authorities claimed nearly toppled their rule in India during the First World War? Seema Sohi traces how Indian labor migrants,students, and intellectual activists who journeyed across the globe seeking to escape the exploitative and politically repressive policies of the British Raj, linked restrictive immigration policies and political repression in North America to colonial subjugation at home. In the process, theydeveloped an international anticolonial consciousness that boldly confronted the British and American empires. Hoping to become an important symbol for those battling against racial oppression and colonial subjugation across the world, Indian anticolonialists also provoked a global inter-imperialcollaboration between U.S. and British officials to repress anticolonial revolt. They symbolized the hope of the world's racialized subjects and the fears of those who worried about the global disorder they could portend. Echoes of Mutiny provides an in-depth and transnational look at the deeply intertwined relationship between anti-Asian racism, Indian anticolonialism, and state antiradicalism in early twentieth century U.S. and global history. Through extensive archival research, Sohi uncovers the dialecticalrelationship between the rise of Indian anticolonialism and state repression in North America and demonstrates how Indian anticolonialists served as catalysts for the implementation of restrictive U.S. immigration and antiradical laws as well as the expansion of state power in early twentiethcentury India and America. Indian migrants came to understand their struggles against racial exclusion and political repression in North America as part of a broader movement against white supremacy and colonialism and articulated radical visions of anticolonialism that called not only for the endof British rule in India but the forging of democracies across the world.
