The Nadar community was not a single caste, but developed from an assortment of related subcastes, which in course of time came under the single banner Nadar. Nadar climbers were the largest subsect of today's Nadar community. A few subsects of the Nadar community, such as the Nelamaikkarars, were traditionally wealthy landlords and money lenders. Historically, most Nadars were cultivators of palmyra trees and jaggery and a few were also involved in the toddy trade. Nadar climbers had faced discrimination from major upper castes in some regions. The martial art of Varma Kalai was historically practiced by the Nadars.
