AJGAR stands for- Ahir,Jat ,Gujjar and Rajputs.
They all have common roots and all of them are the decendents of King Yadu. It is said that if these four tribes unite together then they will become unconquerable like AJGAR or pythone.
According to the historian 'Ram Lal Hala' the word Jat is drived from word 'Yat'. There was a king named 'Yat' in Chandravanshi clan who was ancestor of Lord Krishna. The Jats are descendants of King Yat. 'Yat' later changed to 'Jat'.
On the basis of historical facts the Jats are reported to be present in India from 3102 BCE. Dr Natthan Singh writes that Jats were the Aryans and their original homeland was 'Saptasindhu'. They had to migrate from India on economic, social and political reasons after Mahabharata War for some period but they returned back to India. In the migration also they did not leave their language and cultural traditions. This view is also supported by Thakur Deshraj who writes that on the basis of ethnological, physical, cultural and linguistic characters Jats Aryans who inhabited the areas on the banks of Ganga-Yamuna or Sarswati-Sindhu during Vedic civilization. Thakur Deshraj also tells that after the great Mahabharata war Krishna formed a democratic federation or sangha of clans known as Jñātisangha. Initially Vrishni and Andhaka clans were included in this sangha and later many clans joined it. Due to political situations Jats had to migrate from India. They went up to Iran, Afghanistan, Arab, Turkistan . Chandravanshi Kshatriyas known as Yadavas spread to Iran Sindh, Punjab, Saurashtra, Central India and Rajasthan. In north-east the went upto Kashmir, Nepal, Bihar etc.. Even they went to Mongolia and Siberia. Greeks call themselves descendants of Krishna and Baladeva. China vanshi also consider themselves descendants of Aryans. The same people return to India in later periods with the names Shaka, Pahllava, Kushan, Yuezhi, Huna, Gujar
The Sinsinwar Jat rulers of Bharatpur have been recorded as Yadav, by Prakash Chandra Chandawat. Historian UN Sharma has mentioned the chronology of Krishna in which starting from Sindhupal in 64th generation of Krishna to Bharatpur ruler Maharaja Brijendra Singh (1929-1948) all the rulers are mentioned as Yaduvanshi Jats. Sidhu Jats are also Bhatti Rajput in origin, and thus Yaduvanshi in origin.
