KshatriyaKshatriya (क्षत्रिय) (from Sanskrit kṣatra, "rule, authority"; also called Rajanya) is one of the four varna (social orders) of Hindu society and is associated with warrior aristocracy. The Sanskrit term kṣatriyaḥ is used in the context of later Vedic society wherein members were organised into four classes: brahmin, kshatriya, vaishya and shudra. The administrative machinery in the Vedic India was headed by a tribal king called Rajan whose position may or may not have been hereditary.
