Ennayiram was a Vedic college established by Rajendra I, which is now at Villupuram district. About 340 students were learning the Vedas, grammar and Upanishads under 14 teachers. This was later followed by his successors, and as a result, two more such colleges had been founded, at Tirubuvanai (near present-day Puducherry) and Tirumukkoodal (in present-day Chengalpattu district), in 1048 and 1067, respectively.
The great literary works Periyapuranam and Kamba Ramayanam belong to this period.
