Shrikant G Talageri was born in 1958, educated in Mumbai, India where he lives and works. Talageri has revolutionized the research into Rig Veda. He has successfully identified several historical information from Rig Veda, which he used to chronologically arrange the ten Mandalas of Rig Veda (6, 3, 7,, 4, 2, 5 and 8,9,10) . He explored the history of the kings and the sages who composed the Rigvedic hymns. Talageri utilized for his analysis, the Anukramanis in Rigveda, which are often neglected by scholars. He also studied the geographical basis of Rig Veda. As a corollary of his analysis, he establishes that Rig Veda was composed by sages living in Saraswati river valley between Saraswati and Ganga rivers (Hariyana) who were patrons of the kings who ruled in this area. These patron kings were especially the Puru and particularly the Bharata branch of the Purus. He also analyzed the probable location of origin (Punjab) of the Iranians and the Europeans. Talageri equates the Vedic-Aryans to the Purus and the Iranians to the Anus a sibling branch of the Purus. Other sibling branches includes the Drahyus, the Yadus and the Turvasus.
