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. At its peak, the Toungoo Empire was the largest and strongest empire in Southeast Asia. However, it collapsed in the 18 years following Bayinnaung's death in 1581.
