In the early 16th century the Portuguese made commercial contacts with the town and established a commercial centre in 1554 CE. The Portuguese also conducted missionary enterprise here. In 1658, the Dutch made an agreement with King Vijaya Nayakkar of Thanjavur on 5 January 1662, by which ten villages were transferred from the Portuguese to the Dutch — Nagapattinam Port, Puthur, Muttam, Poruvalancheri, Anthanappettai, Karureppankadu, AzhingiMangalam, Sangamangalam, Thiruthinamangalam, Manjakollai, Nariyankudi. Ten Christian churches and a hospital were built by the Dutch. They released Pagoda coins with the name Nagapattinam engraved in Tamil. As per agreement between the first Maratta King Egoji of Thanjavur and the Dutch, Naagapattinam and surrounding villages were handed over to the Dutch on 30 December 1676. In 1690, the capital of Dutch Coromandel changed from Pulicat to Nagapattinam.
