Kartavirya
Kartavirya (कार्तवीर्य) (Also known as Kartavirya Arjuna) or Sahasrarjuna or Sahasrabahu was a king of Haihaya Vansha. He was a legendary king of an ancient kingdom during the Ramayana period with capital at Mahishamati which is on the banks of Narmada River in the current state of Madhya Pradesh. Kartavirya was son of Kritavirya, king of the Haihayas. This is his patronymic, by which he is best known; his real name was Arjuna. He is described as having a thousand hands and a great devotee of god Dattatreya.
In Jat history
History of the Jats:Dr Kanungo/Origin and Early History (p.11-12) writes that There is no greater improbability in deriving Jat, Jat or Jut, - as the tribal name is pronounced in various forms in the different provinces from the Indian Yadu or Yadava than from the Chinese Yuti or Ye-ta-li-to. If the phonetic difficulty alone stands in the way of recognising the Yadava origin of the Jats, there cannot be any objection in identifying the Jats with the Jatas or Sujatas, a branch of the great Haihaya Yadavas.
Hundred sons of Kartavirya
Of the hundred sons of Kartavirya, the five principal were Sura, Surasena, Vrishana, Madhu and Jayadhwaja. From the last sprang up the five great divisions of the Haihaya tribe, the Talajanghas, Vitihotras, Avantyas, Tundikeras, and Jatas also called Sujatas from the prolific number (Wilson's Vishnu Puran pp. 417-418). Wilson seems to entertain a doubt whether the Haihayas are not the Huna and Saka tribes engrafted upon the great genealogical tree of the Aryans by the clever Puranic ethnologists. The Jats were known by the name of Sus, Abars, and many other names, as Beames says. We shall meet these contentions in the appendix "The Yadus.
