K. N. Sivaraja Pillai

Pillai stressed analysis of historicity of tradition in the study of ancient Tamil history. In his 1932 book, Chronology of the Ancient Tamils, he wrote, "...venerable as the Sangam tradition in the Tamil land first put into shape by the commentator on [Iraiyanar Akapporul] and sedulously propagated by later commentators, we have to examine it closely and satisfy ourselves first about its authenticity and secondly for its evidentiary value for the purposes of history."

Sivaraja Pillai was regarded as a pioneer in the study of ancient verbal terminations.^[3]
