Christian Friedrich Schwartz was a German Lutheran Pietist missionary who worked among the Tamil people in southern India from 1750 to 1798. He witnessed the English East India Company’s unstoppable rise and transformation from a mercantile enterprise to a colonial governing power. He came to Tranquebar in 1750l twelve years later, at the invitation of the English military officers and soldiers, he joined the Society for Promoting Christian Knowledge, which had Anglican roots. His lifestyle radiating values and honesty persuaded the Hindu and Muslim rulers to seek his diplomatic services. The Company sent him as its emissary to Hyder Ali and other stakeholders. Amid his tireless public service, he remained a Lutheran missionary, establishing churches and schools, training catechists, ordaining Tamil pastors, and directing their work. After his death, the Company erected a marble monument in St. Mary’s Church in Fort St. George (now in Chennai). King Serfoji, Schwartz’s adopted son, likewise built two monuments, one in marble and the other in granite, and placed them in two churches in Thanjavur. This essay examines, for the first time, the content of these three monuments and places them within the larger context of Schwartz’s public ministry. It draws on archival documents held in the famous Mission Archives of the Francke Foundations (AFSt/M) in Halle (Saale), Germany, and the India Office Records and Private Papers (IOR) at the British Library in London, England. My most recent biography of Schwartz (2025) sheds further light on all persons, places, processes and events mentioned in this essay.
