Kuru Kingdom
Kosambi was one of the greatest cities in India from the late Vedic period until the end of Maurya Empire with occupation continuing until the Gupta Empire. As a small town, it was established in the late Vedic period, by the rulers of Kuru Kingdom as their new capital. The initial Kuru capital Hastinapur was destroyed by floods, and the Kuru King transferred his entire capital with the subjects to a new capital that he built near the Ganga-Jamuma confluence, which was 56 km away from the southernmost part of the Kuru Kingdom now as Prayagraj previously called Allahabad.
