The kings of the Pandyan Dynasty are frequently mentioned in Sangam literature of the third century BCE and onwards, in literary works such as the "Mathuraikkanci" and other early Tamil literary works such as "Cilapatikaram", which have been used by historians to identify their names and, to some extent, their genealogy. Nedunjeliyan II is referred to as the most popular warrior among the Early Pandyas, winning a battle at Talaialanganam against a coalition of forces from Cholas and Cheras and five other kingdoms. The early Pandyan kingdom extended between Travancore in the west, Vellaru river in the north and all the way to the ocean in the east and the south.
