When the Jesuit missionaries returned in the 1830s, following the revival of their Society, they were shocked at the lapse in formal religious observance and in general Christian morality, as well as the opulent lifestyle being led by the Paravar elite which contrasted with the dilapidated state of the churches. Around that time the elite, along with some other groups such as Nadar traders, were making significant amounts of money from a surge in export demand for processed cotton, using their existing wealth from the pearl fisheries as a means to expand their interests into this booming sector. By 1845 Tuticorin was the location of the main cotton export activities in southern India and by the end of the century it was the fifth largest port in the entire of India.
