Pagan kingdom

To the north another group of people, the Burmese began infiltrating the area as well. By 849, they had founded a powerful kingdom centred on the city of Pagan (now spelled Bagan) and filled the void left by the Pyu. The kingdom grew in relative isolation until the reign of Anawrahta (1044 - 77) who successfully unified all of Myanmar by defeating the Mon city of Thaton in 1057. Consolidation was accomplished under his successors Kyanzittha (1084-1112) and Alaungsithu (1112-1167), so that by the mid-12th century, most of continental Southeast Asia was under the control of either the Pagan Kingdom or the Khmer Empire. The Pagan kingdom went into decline as more land and resources fell into the hands of the powerful sangha (monkhood) and the Mongols threatened from the north. The last true ruler of Pagan, Narathihapate (reigned 1254-87) felt confident in his ability to resist the Mongols and advanced into Yunnan in 1277 to make war upon them. He was thoroughly crushed at the Battle of Ngasaunggyan, and Pagan resistance virtually collapsed. The king was assassinated by his own son in 1287, precipitating a Mongol invasion in the Battle of Pagan; the Mongols successfully captured most of the empire, including its capital, and ended the dynasty in 1289 when the Mongols installed a puppet ruler in Myanmar.
