Sindhuveli! Sinauli! Samama? Sammadhama?

2000 BC - A war breaks out at Sinauli, on the banks of the Yamuna River, around the same time when the cities of Indus named Mohenjo-daro and Harappa fell. The 'Battle of the Ten Kings', as it is called in 'Rig Veda' finally ends at the river Yamuna. What is the connection between the two? What is the connection between the Vedic period which begins after this and the Tamil language which was spoken in the northern region of present day India gets altered? Who were the Nagas faced by King Sudas and Vashista? Which Pandyan king is found in the 'Pashupathi Seal'? Who are the ancestors of the fictional characters in the Mahabharata? There is only one answer to all these questions. He was the commander of Kapadapuram, Nedunchezhiyan.
