Toungoo briefly built Southeast Asia's largest empire
From a Sittaung River outpost, Burma's Toungoo kings reunited Pagan's lands, absorbed Shan realms, and reached Assam to Cambodia's marches. Bayinnaung's death in 1581 shattered the first empire; a leaner Ava restoration lasted until Mon rebels took Inwa in 1752.
The Toungoo—or Taungoo—dynasty ruled Burma from the mid-sixteenth century to 1752, remembered in Burmese historiography as the Second Burmese Empire and, after 1599, as the Nyaungyan line. At its height it claimed suzerainty from Assam and Manipur to the Cambodian marches and from Arakan's borders to Yunnan—probably Southeast Asia's largest empire. Mingyi Nyo founded the First Toungoo Empire at Taungoo in 1510 as Ava crumbled; after Shan forces took Inwa in 1527, Burmese speakers flocked south and the town became a new power center.
Tabinshwehti reunified most of Burma, crushed Hanthawaddy's capital at Bago, and was crowned at Bagan in 1544. He shifted the capital to commercial Bago, failed against Arakan and Ayutthaya (1547–49), and was assassinated in 1550. Brother-in-law Bayinnaung then ruled thirty years, taking Manipur (1560) and Ayutthaya (1564) and stretching influence from Laos to Siam before dying in 1581 on the eve of an Arakan campaign. Within eighteen years the overstretched realm collapsed; Nyaungyan Min and Anaukpetlun rebuilt a smaller kingdom of Lower and Upper Burma, Shan States, and Lan Na by 1622.
Restored kings at Ava replaced valley hereditary chiefs with appointed governors, trimmed Shan hereditary rights, and ran censuses from 1635—Thalun's inquest then estimated about two million people in the Irrawaddy valley. Trade and secular reforms underwrote more than eighty years of prosperity before palace politics, Meitei raids from the 1720s, Chiang Mai revolt, and the 1740 Mon rising that founded Restored Hanthawaddy. Hanthawaddy armies captured Inwa in 1752, ending 266 years of Toungoo rule; Konbaung successors still inherited much of the legal-political template.
