Mong Mao in the context of "Toungoo dynasty"

The Toungoo dynasty (Burmese: တောင်ငူမင်းဆက်, [tàʊɰ̃ŋù mɪ́ɰ̃ zɛʔ]; also spelt Taungoo dynasty, and also known as the Nyaungyan dynasty after 1599, was the ruling dynasty of Burma (Myanmar) from the mid-16th century to 1752. At its peak, Toungoo "exercised suzerainty from present-day Assam, Manipur to the Cambodian marches and from the borders of Arakan to Yunnan" and was the largest empire and the only great power country in the history of Southeast Asia." The dynasty ruled in two periods: the First Toungoo Empire (1510–1599) and the Nyaungyan Restoration (1599–1752).

Its early kings Tabinshwehti and Bayinnaung succeeded in reunifying the territories of the Pagan Kingdom for the first time since 1287 and in incorporating the Shan States for the first time, in addition to including Manipur, Chinese Shan States, Siam and Lan Xang. The empire collapsed in the 18 years following Bayinnaung's death in 1581. The dynasty quickly regrouped under the leadership of Nyaungyan Min and his son, Anaukpetlun, who succeeded in restoring a smaller, more manageable kingdom, encompassing Lower Burma, Upper Burma, Shan States and Lan Na by 1622. The Restored Toungoo kings, now based in Ava (Inwa), created a legal and political system whose basic features would continue under the Konbaung dynasty well into the 19th century. The crown completely replaced the hereditary chieftainships with appointed governorships in the entire Irrawaddy valley and greatly reduced the hereditary rights of Shan chiefs. Its trade and secular administrative reforms built a prosperous economy for more than 80 years.
