III. Burma (Pagan) Buddhism
In 1057 A.D. King Anuruddha (Anawratha) became powerful in the whole of Burma, having his capital at Pagan (Central Burma). Anuruddha extended his kingdom right up to Thailand, especially the Northern and Central parts, covering areas now known as Chiengmai, Lopburi, and Nakon Pathom. Being a Theravada Buddhist, Anuruddha ardently supported the cause of Theravada which Burma, like Thailand, at first received directly from India through missionaries sent by Emperor Asoka. However, at the time under consideration, Buddhism in India was already in a state of decline, and as contact between Burma and India was then faint, Theravada Buddhism, as prevalent in Burma at that time, underwent some changes and assumed a form somewhat different from the original doctrine. This, at a later stage, became what is known in Thailand as Burma (Pagan) Buddhism. During the period of King Anuruddha's suzerainty over Thailand, Burmese Buddhism exercised great influence over the country, especially in the North where, owing to proximity, the impact from Burma was more felt.
