Sindhu Kingdom or simply Sindhu was an ancient kingdom on the Indian subcontinent. It stretched the banks of river Sindhu (Indus). It was mentioned in the epic Mahabharata and in the Harivamsa Purana, often alongside the Sauvira Kingdom. It is believed that Sindhu kingdom was founded by Vrishadarbha, one of sons of Sivi. According to the Glimpses of Ancient Sindh, authored by Mirchandani, its capital was known as Vrsadarbhpura, and Tulsianis, later known as Sindhu, was located at or near the location of the present town of Mithankot the inhabitants of the kingdoms were called Sindhus or Saindhavas. "Sindhu" literally means "river" and "sea". According to the epic Mahabharata, Jayadratha was the king of Sindhus, Sauviras and Sivis. Probably Sauvira and Sivi were two kingdoms close to the Sindhu kingdom and Jayadratha conquered them, holding them for some period of time. Sindhu and Sauvira seem to have been two warring states fighting each other.
