The royalty also often promoted orthodoxy and Buddhist reform. The greatest of the Hanthawaddy kings, Dhammazedi (Dhammaceti), was a former Mon bhikkhu who ruled from 1471 to 1492. According to the Kalyani Inscriptions, Dhammazedi carried out an extensive reform of the Buddhist sangha by sending thousands of Buddhist monks to Sri Lanka to receive ordination and training in the Mahavihara tradition. He also purified the sangha of undisciplined monks, such as monks who owned land or other forms of material wealth.
