Hsinbyushin (, , ; ; 12 September 1736 – 10 June 1776) was king of the Konbaung dynasty of Burma (Myanmar) from 1763 to 1776. The second son of the dynasty founder Alaungpaya is best known for his wars with Qing China and Siam, and is considered the most militaristic king of the dynasty. His successful defense against four Qing invasions preserved Burmese independence. His 1765 invasion of Ayutthaya brought an end to the Ayutthaya Kingdom. The near simultaneous victories over Qing and Siam has been referred to as testimony "to a truly astonishing elan unmatched since Bayinnaung." He also raised the Shwedagon Pagoda to its current height in April 1775.
The deputy commander-in-chief during his father's reunification campaigns (1752–1759), Hsinbyushin as king pursued an expansionist policy against his neighbors. By 1767, his armies had put down a rebellion in Manipur, captured the Laotian states, sacked and destroyed Ayutthaya, and driven back two invasions by China. However, his reckless decision to wage two simultaneous wars against China and Siam nearly cost the kingdom its independence. The third Chinese invasion forced Hsinbyushin to hastily withdraw from Siam, until an uneasy truce in 1769.
The specter of war kept the state heavily militarized, setting the stage for army commanders to mistreat the population. In 1773, the army command provoked a rebellion by ethnic Mon troops, only to suppress the mutiny with "undue severity". The warlord behavior by local governors and army commanders only increased in 1774 when Hsinbyushin suffered from what turned out to be a long illness that would ultimately claim his life. In 1775, periphery vassals states of Lan Na and Manipur both revolted. He died in June 1776 while the Burmese forces were still engaged in Siam and Manipur. The Burmese armies withdrew from Siam right after his death, leaving Lan Na under Siamese control. His wars would eventually lead to the present-day Burmese control of the Taninthayi Region, the Northern and Eastern portions of Shan State, and Kachin State.
Early life
The future king was born Maung Ywa () to Aung Zeya and Yun San in Moksobo, a large village in the Mu river valley located about 60 miles northwest of Ava, on 12 September 1736. His father Aung Zeya was the chief of the village of a few hundred households, and was part of gentry families that had administered the Mu valley for generations. His father came from a large family, and was related by blood and by marriage to many other gentry families throughout the valley. Aung Zeya claimed descent from a 15th-century cavalry commander and ultimately the Pagan royal line.
Ywa grew up during the period in which the authority of King Mahadhammaraza Dipadi of the Toungoo dynasty had largely dissipated across the kingdom. The Manipuris had been raiding increasingly deeper parts of Upper Burma between the Chindwin and Irrawaddy rivers since the mid-1720s. Ywa's home region was directly on the path of the raids, and took the brunt of the raids. With the Burmese court unable to deal with the small kingdom of Manipur, the Burmese watched helplessly as the raiders torched villages, ransacked pagodas, and taking away captives. In 1740, the Mon of Lower Burma broke away, and founded the Restored Hanthawaddy Kingdom. The central authority of the king had effectively disappeared, and a profound sense of helplessness pervaded and deepened. The Hanthawaddy armies finally toppled the Toungoo dynasty on 23 March 1752 when they captured Ava.
Military commander (1752–1760)
On 29 February 1752, three weeks before the fall of Ava, Aung Zeya founded the Konbaung dynasty to resist the upcoming Hanthawaddy rule, styling himself King Alaungpaya. The Konbaung resistance was just one of many resistance forces that had sprung up across Upper Burma (mostly by panicked ethnic Burmans but also by ethnic Shans). Many young men from 46 villages in the Mu valley, who longed to redress the humiliations of the previous decades, answered Alaungpaya's call. The 15-year-old Ywa enthusiastically joined his father's call. (He would later prove to be the most militaristic of all Konbaung kings).
