Christianity in the state of Tamil Nadu, India is the second largest religion in the state. According to tradition, St. Thomas, one of the twelve apostles, landed in Malabar Coast in AD 52. In the colonial age many Portuguese, Dutch, British and Italian Christians came to Tamil Nadu. Priests accompanied them not only to minister the colonisers but also to spread the Christian faith among the non-Christians in Tamil Nadu. Currently, Christians are a minority community comprising 6% of the total population. Christians are mainly concentrated in the southern districts of Tamil Nadu - Kanyakumari, Thoothukudi and Tirunelveli.
