We know that of the 5 ever undefeated kings of India, 3 belonged to the Tamil country.
Can we document their greatest nemesis and some one(king/chieftain/general) who challenged them.
I remember reading someplace about where RJC and a older Vanthiyadevar fought a tooth and nail battle with the Nagas, not sure if it was RJC or RRC. Ofcourse, ravidasan the all time classic on RRC proxy war.
Do we have more information on these infamous Nemesis of the greats who ruled in the dravidian land?
