Introduction / History
The Barwar are Hindu caste, found in North India. The Barwar are a denotified tribe, one of the tribal groupings that was deemed as criminal under the Criminal Tribes Act.

The community is said to have originated in the Saran district of Bihar. They were expelled from Saran, by the local Raja, and settled in the Awadh region. The Raja of Bast, in Awadh then expelled them again, as they continued their marauding activities in his dominion. They have three subdivisions, the Sawang, Gulam and Tilam. The Sawang group considers itself to be of pure Barwar origin, while the other two groupings are descendants of individuals kidnapped by the Sawang.

The Barwar historically were a community associated with marauding and plunder. The British colonial authorities made various attempts to suppress their brigandage. With the departure of the British, the community was denotified. The Barwar now have scheduled caste status.
