Manginglong

During his reign, he completed the second unification of Burma, captured Siam and other places, and established Burma's hegemony in the Indochina Peninsula. He was called the "Three Great Emperors of Burma" together with Anurutta and Yong Ji Ya.

Awa was captured in 1555, and later conquered the northern Shan states, completing the second reunification of Myanmar, making its territory beyond the Bagan Dynasty, extending to Manipur in the west, to Lincheng (now Vientiane, Laos) and Keng Mai (now Chiang Mai, Thailand) in the east, and to the jurisdiction of nine Shan chieftains on the China-Myanmar border. It was the heyday in Myanmar's history. During his tenure, his political achievements were remarkable. On the political front, in order to unite all ethnic groups, the power in the Privy Council was not divided into Shan, Meng and Myanmar, and all ethnic groups were equal and occupied the same seats. On the economic front, we encourage the widespread cultivation of rice in the Ayeyarwaddy River Delta to develop agriculture, and use captured craftsmen to develop lacquerware imported from Jingmai and weaving, textile, smelting and glass manufacturing technologies imported from Manipur to develop handicrafts, formulate a unified measurement and monetary system, and promote the development of domestic and foreign trade.

In terms of legislation, in addition to ordering the compilation of the "Famous Code" and the "Nine Collections of the Code", the cases he personally decided were compiled into a code known in history as the "White Elephant King Judgment Volume", which served as the basis for officials across the country to try cases. In terms of transportation, due to the needs of the war, two main trunk lines were built from Baigu (present-day Bago) to Donggu and to Baimou, laying the foundation for the development of domestic transportation. However, due to militarism, Siam was attacked many times, resulting in barren farmland and poor people's livelihood. This led to the Pegu Peasant Uprising in 1564 and the Great Famine in 1567, which shook the rule of the Donggu Dynasty.
