Echoes of Mutiny explores how the challenges of Indian migrants to racial exclusion in the United States and Canada and British supremacy at home provoked a global inter-imperial collaboration between U.S. and British officials to repress those deemed a threat to the racial and imperial world order. In Echoes of Mutiny, Seema Sohi provides us with an expansive account of the radicalism-and the repression -of a group of Indian anti-imperialists who found a short-lived home in the United States of the early 20th century. While historians of South Asia have often treated these expatriate radicals as a small overseas outpost of the Indian independence movement, Sohi draws on a range of archival evidence to make a bolder argument: that members and associates of the Ghadar party were simultaneously contesting British colonialism and U.S. racialization and exclusion-and that their experiences produced a vision of revolutionary change that was global rather than merely national in its scope... Sohi's work is transnational history at its best: it is as dense, complex, and deeply researched as it is beautifully written.
