We are in a continuous process of search. This is an advantage of WIKI. Members are requested to provide evidences here instead of asking. In the past the ruling clans could be traced from Afghanistan to the remotest eastern India. The Magadha Ruler Mauryas had gone from North so we can not rule out common factors between the present geographical distribution and the past geography of Jats. Let us not follow Wikipedia as it is continuously deleting Jat content from it as our members are not taking much interest in expanding content on Wikipedia. Regarding common factors in Rajasthan and eastern India I again quote RC Majumdar -
"The Copper Age civilisation in eastern India had links with similar civilisation of central India and Rajasthan".(Majumdar, R.C., History of Ancient Bengal, 2005 edition, pp. 20-22)
Bhim Singh Dahiya has mentioned about the rule of Munda people in Magadha. The inscriptional evidences show that Jat rulers and tribes in north India from Kabul to Cuttack, in the period following the disintegration of Kushanas empire. Particularly Magadha area was under the rule of people who had the title,
Murunda. They are admitted to be Sakas or
Scythians (=Jats). [Bhim Singh Dahiya, Jats The Ancient Rulers, p.188]
These Murunda rulers of Patliputra had special relations with Peshawar. It was but natural, for, after all Murundas and Kushanas both belonged to the same Scithian stock
(=Jats). [Bhim Singh Dahiya, Jats The Ancient Rulers, p.189]
Mundas belong to the hill men of the north, who are spread over the Himalayan and Vindhyan mountains from the
Indus to the Bay of Bengal. (
