The Third or Later Sangam period was between 600 BCE and 300 CE.

Please note: According to current knowledge, there is no scientifically based evidence for the existence of these kings of the Sangam period. The main source is the Sangam literature – particularly religious literature such as Periyapuranam, semi-biographical poems of the later Chola period, as well as the temple and cave inscriptions and the records left by medieval Cholas.
