Accession Shortly after he became
saopha, the Ava court came calling. King
Thohanbwa, who was deeply unpopular with his subjects even before his military defeats against Toungoo Dynasty, had been assassinated in May 1542 (Kason 904 ME). The court elected Hkonmaing king in June 1542 after the leader of the court insurrection,
Yan Naung, rejected the offer. Yan Naung agreed to remain in office and advise the new king for one year. The House of Mohnyin was furious. Not only did they believe the Ava throne rightfully belonged to them but they were also appalled by Thohanbwa's assassin Yan Naung remaining in office. Nevertheless,
Sawlon II of Mohnyin relented since the Confederation was in the middle of a serious war with Toungoo. The Confederation leadership reluctantly accepted Hkonmaing as king of Ava in August/September 1542, and agreed to continue the war.
War with Toungoo Hkonmaing prepared for war in the next 12 months. All seven Confederation states (Ava, Mohnyin, Momeik, Hsenwi, Bhamo, Hsipaw and Yawnghwe) had agreed to contribute manpower and materiel. He was not able to persuade King
Min Bin of
Arakan to stay in the alliance however. In December 1543, he personally led the Confederation's armies and navies, and invaded Lower Burma. After initial successes, they were decisively driven back by February 1544. They could not stop advancing Toungoo forces which took all the way up to
Pagan (Bagan). It was a complete disaster for Hkonmaing. He had not only failed to retake Prome but also managed to lose all of central Burma. The Confederation leadership was unsure how to respond. They sent a small army led by
Sithu Kyawhtin as a probe in late 1544, which was subsequently destroyed at
Salin.
War with Mohnyin By then, Sawlon II's patience had run out. He sent Sithu Kyawhtin with an army of 5,000 to take Ava. Sithu Kyawhtin easily took
Sagaing, and attacked
Ava (Inwa). The arrival of the rainy season of 1545 saved the day for Hkonmaing. But his territory was now badly splintered: the Mohnyin-controlled west of the Irrawaddy (present-day Sagaing Region and southern Kachin State), and Hsipaw/Onbaung-controlled eastern half (approximately, northern Mandalay Region and western Shan State). He died during the rainy season c. September 1545. He was 48. ==Notes==
