Chero
The Chero were a Hindu tribal people of the lower Ganga plain, whose chiefs held Rohtas around 1337. Their chiefdoms had emerged in Bhojpur and Saran after the fall of the Pala Empire.
Rivalry with the Ujjainiyas drove them south towards Palamu, where Bhagwant Rai seized power in 1572. The Mughals subdued Anant Chero in 1590 and carried off fifty-four elephants. Medini Ray ruled from 1620 to 1634 and sacked Navratangarh, the Khokhra capital. In 1814 the East India Company confiscated Raja Churaman Rai's zamindari, ending the Chero state.
