The observance of Kumbh Mela dates back many centuries in Ancient India, to the Vedic period, where the river festivals first started getting organised. In Hindu mythology Kumbh mela's origin is found in one of populor creatio myths about Samudra Mathan, It was done by churning ocean of milk

The Gods had lost their strength, and to regain it, they thought of churning the Ksheera Sagara (primordial ocean of milk) for amrit (the nectar of immortality), this required them to make a temporary agreement with their arch enemies, the demons or Asuras to work together, with a promise of sharing the nectar equally thereafter . However, when the Kumbha (urn) containing the amrita appeared, a fight ensued. For twelve days and twelve nights (equivalent to twelve human years) the gods and demons fought in the sky for the pot of amrita. It is believed that during the battle, Lord Vishnu flew away with the Kumbha of elixir, and that is when drops of amrita fell at four places on earth: Prayag, Haridwar, Ujjain and Nashik, and that is where the Kumbh Mela is observed every twelve years.
