In 1680, the first congregation of Nadars was started at Vadakkankulam with the conversion of a Nadar woman. The Nadar converts came neither from the lowest sections( Kalla Shanar) of the castes nor from the highest(Nadans), but from the middle subgroups and particularly the climbers. The converts were provided protection by the missionaries from the oppressions of Nadan landlords. With their traditional dominance threatened, the Nadans became the missionaries' greatest adversaries. Many Nadans supported anti-Christian societies such as the Vibuthi Sangam(the Sacred Ashes Society). However by the 1860s the opposition of the Nadans began to wane. Eventually a few Nadans actually converted to Christianity.
Nadans of Travancore
The Nadar climbers of Southern Travancore served as palmrya climbers on the lands of aristocratic Nadans in the eastern portion of Kanniyakumari. In the tradition of these Nadan families the lands were bestowed by the kings of Travancore in return for the Nadans' services.
Distinctions within the Nadar community today
The Nadan families today still retain some aura of aristocracy and authority. However, the distinctions which separated them from the rest of the Nadar community are largely gone as their once dependent climbers have gained education and improved their status greatly. The once Nadar climbers are today widely into education, business and other important fields.
