Sauvira kingdom

Sauvīra was an ancient kingdom of the lower Indus Valley mentioned in the Late Vedic[3] and early Buddhist literature and the Hindu epic Mahabharata.

Its capital city was Roruka, identified with present-day Aror/Rohri in Sindh, mentioned in the Buddhist literature as a major trading center.

(3:269)[12] In section 22 of book 11, Jayadradtha is again mentioned as the king of Sindhu and Saivira, and being married to — besides Dussala (the sister of Duryodhana) — two other wives, one from Gandhara and the other from Kamboja.

The dark and handsome young man, the scourge of his enemies, standing at the edge of that tank, is the son of Suvala of the race of Ikshwaku.

And if, O excellent lady, thou hast ever heard the name of Jayadratha, the king of Sauviras, even he is there at the head of six thousand chariots, with horses and elephants and infantry, and followed by twelve Sauvira princes as his standard-bearers, named Angaraka, Kunjara, Guptaka, Satrunjaya, Srinjaya, Suprabiddha, Prabhankara, Bhramara, Ravi, Sura, Pratapa and Kuhana, all mounted on chariots drawn by chestnut horses.

Arjuna and the other Pandava princes became so powerful that they slew in battle the great Sauvira who had performed a sacrifice extending over three years, undaunted by the raids of the Gandharvas [alternatively Gandharas].

Then again Vipula, the king of the Sauviras, endued with great prowess, who had always shown a disregard for the Kurus, was made by the intelligent Arjuna to feel the edge of his power.

And Arjuna also repressed by means of his arrows (the pride of) king Sumitra of Sauvira, also known by the name of Dattamitra[,] who had resolutely sought an encounter with him.

(6:20)[20] "The Abhishahas, the Surasenas, the Sivis, and the Vasatis, the Swalyas, the Matsyas, the Amvashtas, the Trigartas, and the Kekayas, the Sauviras, the Kitavas, and the dwellers of the eastern, western, and northern countries were all resolved to fight reckless of the lives."

"[M]any combatants also, belonging to the Nishadas, the Sauviras, the Valhikas, the Daradas, the Westerners, the Northerners, the Malavas, the Abhighatas, the Surasenas, the Sivis, the Vasatis, the Salwas, the Sakas, the Trigartas, the Amvashthas, and the Kekayas, similarly fell upon him" (Arjuna).

(6:118)[22] Bhishma the son of Santanu, protected by the warriors headed by Saindhava and by the combatants of the East and the Sauviras and the Kekayas, [fought] with great impetuosity.

(6:52)[23] "[T]he diverse tribes of the Sauviras, the Vasatis, and the Kshudrakas, and the Malavas, all these, at the command of the royal son of Santanu [Bhishma], quickly approached Kiritin [Arjuna] for battle."
