Later history Some scholars have held that the rulers of Sri Lanka ensured that Theravāda remained traditional, and that this characteristic contrasts with Indian Buddhism. However, before the 12th century CE, more rulers of Sri Lanka gave support and patronage to the Abhayagiri Theravādins, and travelers such as Faxian saw the Abhayagiri Theravādins as the main Buddhist tradition in Sri Lanka.
