My work examines the pivotal influence of British Protestant missionaries in suppressing the practice of casteism in Kerala, India during the nineteenth and twentieth centuries. By demonstrating the impact of these missionaries upon the lower caste community of Cochin and Travancore, my study engages with the long-running academic debates around the role of missionaries as a part of colonisation. Although casteism affected every aspect of those from the lower castes, the primary focus of this study will be the discrimination of lower castes by upper castes based on their food habits, and how these were challenged by the irruption of Protestant missionaries against the backdrop of the British conquest of the Indian sub-continent
