After the
first invasion by the
Yuan dynasty,
Narathihapate fled
Pagan. Already experienced commanders, the brothers
Athinkhaya,
Yazathingyan, and
Thihathu strengthened their garrison at
Myinsaing. After the Mongols left,
Kyawswa succeeded his father Narathihapate. But he was just a nominal king of Pagan for he controlled no more than a few miles outside Pagan. Indeed, the Pagan Empire had ceased to exist. Instead, the real power in central Burma rested with the brothers who through their small but well-disciplined army controlled the
Kyaukse district, the most important granary of Pagan. Kyawswa had no choice but to recognize them as lords of Kyaukse. On 19 February 1293 (12th waxing of Tabaung 654 ME), the king appointed the eldest brother as viceroy of Myinsaing, the second brother as viceroy of
Mekkhaya, and the third brother as viceroy of
Pinle. The brothers already behaved like sovereign kings nonetheless. When King
Wareru of
Hanthawaddy (Lower Burma) received recognition as a tributary of the
Sukhothai Kingdom in 1294, it was the brothers, not Kyawswa, who sent a force to reclaim the former Pagan territory of Hanthawaddy. While their attempt to reconquer Hanthawaddy was unsuccessful, it left no doubt as to who held the real power in central Burma. With the three brothers increasingly acting as sovereign kings, Kyawswa sent his son to the Mongols army base in
Tagaung and asked for recognition as their vassal king in January 1297. He received the official recognition and a Chinese title on 20 March 1297. ==Invasion==
