Devanampiya Tissa of Anuradhapura

Tissa, later Devanampiya Tissa, also known as Devanape Tis, was one of the earliest kings of Sri Lanka based at the ancient capital of Anuradhapura. According to the traditional chronology, he ruled from 307 BC to 267 BC, but the modified chronology adopted by modern scholars such as Wilhelm Geiger assigns his reign to 247 BC to 207 BC. His reign was notable for the arrival of Buddhism in Sri Lanka under the aegis of the Mauryan Emperor Ashoka the Great. The primary source for his reign is the Mahavamsa, which in turn is based on the more ancient Dipavamsa.
