Anawrahtā

Also spelt Anorahta, being a Burmese variant of the Pāli form Aniruddha (or Anuruddha). Name of the king of Burma who reigned 1040-77 and who played an important role in the promotion of Buddhism and the consolidation of the country. Following his conversion to Theravāda Buddhism he sought to turn his capital Pagān into a centre for the religion, a goal he realized after a series of military victories which in due course served to unite the country.
