Between 1837 and 1920, 1.3 million indentured labourers migrated from India to sugar plantation colonies in the Indian Ocean and the Caribbean. Voices from Calcutta shows how spokesmen from Calcutta - the capital of British India - disrupted this trade and influenced the lives of these migrants. It follows Calcuttans in their journey of debating, investigating and defending indenture, unfolding a complex web of letters, petitions, interviews and investigative-reports. As the indenture debates influenced lived experience on ships and plantations, and shaped the negotiation of subjecthood and labour rights for the empire's peripatetic labourers, they became a means by which elite Calcuttans negotiated their own position within the empire. This book locates in Calcutta voices of protest that fundamentally defined the contours of post-slavery labouring across the British Empire. Instead of simply emanating from Britain, to be dutifully followed in the colonies, labour legislation was informed by voices from those very colonies.
