The Diocese of Salem comprises of civil districts of Salem and Namakkal. In 1623 Southern Kongunadu, part of Salem District, under Madurai Nayakkars accepted Christianity, through Fr. Robert De Nobili, S.J. and his successors, the Portuguese Jesuits of the Madurai Mission. About 1654, the Italian Jesuits of the Mysore mission had a residence near Hosur.. In 1687, the Mysore Mission laboured in the entire area of the present diocese. Fr. De Cunha died in 1711 at Kapiganathi near Hosur.
