The Syrian Catholics, mostly the Syro-Malabar Catholics, from various parts of Kerala had started migrating to different areas of Tamilnadu years back, i.e., in the first half of the 20th century, for the purpose of job, business etc. The Syrian Catholics who thus came in the beginning were going to the churches of the Latin Rite for fulfilling their spiritual needs. But as the territory of the undivided eparchy of Trichur was extended on 29th April 1955 to the areas of Tamilnadu, co extensive with those of the diocese of Coimbatore they got opportunity to get their spiritual needs fulfilled according to their own Mother Rite. And when the Eparchy of Palghat which was erected on 20th June 1974 bifurcating the then existing Eparchy of Trichur and adding some parishes from the then eparchy of Tellicherry, the pastoral care of the faithful in Tamilnadu was entrusted to Palghat. Later the division of districts in Tamilnadu and the increase in the number of Syrian Catholic migrants in Coimbatore area and the cultural linguistic differences between the faithful of the district of Palghat and those of the four districts of Tamilnadu (i.e. between the faithful of the undivided eparchy of Palghat) necessitated the erection of the new Eparchy of Ramanathapuram with the bifurcation of the Eparchy of Palghat. The new eparchy was inaugurated on 11th April 2010.
