ETHNONYM: Vaishya. The Vaisyas are the third-highest of the four varnas or categories into which Hindu society is traditionally divided, ranking above the Sudras. Vaisya includes a large number of distinct castes of similar ranking, traditionally traders, moneylenders, or farmers. They are entitled to wear a sacred thread.
According to the vedas, there are four varna, or castes. The highest caste, the Brahmins, are scholars and priests. The Kshatriya are warriors and rulers, while the Vaishya are merchants and skilled artisans. Under this system, the Shudra is the largest caste, and a substantial part of Hindu society. People without caste are known by a variety of terms. The Shudra have classically lived lives of service. Slaves were often classified as Shudra, as were cobblers, blacksmiths, maids, cooks, and so forth.
