Portuguese on Coromandel & Mannar Pearl Coasts

The early 16th century saw the Portuguese establishing a significant presence on the Indian subcontinent's eastern seaboard, notably along the Coromandel and Mannar coasts. Their primary motivations were control over the profitable spice trade and the prestigious pearl fisheries of Mannar. Key fortified trading posts, such as São Tomé de Meliapor (Mylapore) and Tuticorin (தூத்துக்குடி), became crucial centers for both their economic ventures and their missionary efforts. Contemporaneous accounts, including those by Portuguese chroniclers like Tomé Pires and limited local Tamil records, portray a dominant maritime power. A notable event was the mass conversion of the Paravars (பரவர்), traditional pearl fishers of the Gulf of Mannar, to Catholicism in the 1530s. This conversion was largely to secure Portuguese protection against Muslim rivals and local rulers, resulting in the enduring Christian community seen today. The Portuguese left behind architectural remnants such as churches and fortresses. Their economic control, however, was built upon a violent mercantile system. They frequently implemented a 'cartaz' system, which required local ships to obtain permits, and enforced their authority through superior naval strength. This period caused considerable upheaval but also integrated Tamil trading networks into a wider, European-dominated global economy. ## Why this matters The Portuguese arrival fundamentally reshaped the geopolitical, economic, and religious landscape of the Coromandel and Mannar coasts. Their influence initiated new trade dynamics, created lasting religious communities, and introduced a coercive commercial system that had far-reaching consequences for the region's inhabitants and its future integration into global trade networks.
