Early royal service He and his younger brother both followed his father's footsteps, and by the late 1250s had entered the royal service. In 1259–60, both brothers accompanied their father, then commander-in-chief, on the second Missagiri campaign (in present-day
Rakhine State). The campaign ended Missagiri's two-year-old rebellion but their father died on the return trip. Both brothers both vied to succeed their father's title Yazathingyan. The king refused but allowed them to serve at his court with the titles of Ananda Pyissi and Yanda Pyissi, respectively.
Chief minister Ananda Pyissi rose to be a minister, by perhaps as early as 1261, and eventually the chief minister by 1271. In the late Pagan period, the chief minister was the first among four or five ministers of the court, and had the responsibility to command the armed forces as well. As chief minister, Ananda Pyissi spent much of the 1270s trying to keep his kingdom out of the advancing grasp of the
Mongol Empire. In 1271, the Mongols, who first captured the neighboring state to the northeast of Pagan in 1253, demanded nominal tribute. Aware of the gravity of the situation, Ananda Pyissi advised the king to use diplomacy, and avoid war. But there was little room to maneuver. Not only did the king refuse to submit, but he sent an army to reconquer the
Wa and
Palaung regions at the border that had gone over to the Mongols. The Yunnan government sent another embassy on 3 March 1273 to Pagan, again demanding tribute. Ananda Pyissi's court tried to stall the Mongol embassy. But the king again refused, and according to the chronicles, he ordered the diplomats executed over the objections of Ananda Pyissi. At any rate, in 1275, the Yunnan government recommended war to the emperor. The emperor agreed. In the ensuing
battle of Ngasaunggyan, the larger Burmese army was defeated by the smaller, more mobile Mongol army. After the dust settled, the Mongols had gained up to Tagaung, and established a Mongol province with a garrison at Tagaung. The 1285 peace negotiations, recorded in a contemporary inscription, were the last known Burmese record of Ananda Pyissi. by an arrow shot. According to Chinese records, the Yunnan prince re-appointed someone by the name of Ananda as the Burmese king's senior official (presumably as chief minister), and that Ananda was killed alongside the king when the king was assassinated. ==Notes==
