In 1914, the SS Komagata Maru crossed oceans and jurisdictions to arrive at the west coast of Canada. Canadian officials, calling on legislative acts designed to limit the immigration of Indians, detained the ship for two months in Vancouver Harbour. Most of the 376 passengers were then forcibly returned to India. Unmooring the Komagata Maru challenges conventional Canadian historical accounts by drawing from multiple disciplines and fields to consider the international and colonial dimensions of the voyage. By situating the history of South Asians in Canada in a global-imperial context, this volume emphasizes the ways in which the Komagata Maru incident is related to issues of colonialism more generally. The contributors offer a critical reading of Canadian multiculturalism through past events and their commemoration. Ultimately, they caution against narratives that present the ship’s journey as a dark moment in the history of a redeemed nation. Unmooring the Komagata Maru demonstrates that, a hundred years later, the voyage of the Komagata Maru has yet to reach its conclusion.
