The Gandhavariya (also known as Gandhawariya and Gandhawaria) are a Rajput clan based in northern Bihar.
In past they ruled over parts of Madhepura district[1] and Saharsa district during medieval times after the decline of the Oiniwar Dynasty.
[2] One of the theories put forward about the origins of the Gandhavariyas is that they originate from a branch of the Karnat dynasty of Mithila that remained in the region after the Karnat king, Harisimhadeva fled to Kathmandu following the invasion of Ghiyasuddin Tughlaq.
[3] The writer Jyotirishwar Thakur recorded the existence of the Gandhavariyas Rajaputas in his 14th century book Varṇa Ratnākara and detailed how they held sway over much of North Bihar.
[5] The zamindari estate of Sonbarsa Raj was established by Raja Ranjit Singh who belonged to the Gandhavariya clan.
