The Toungoo dynasty (Burmese: , [t m z]; also spelt Taungoo dynasty), and also known as the Restored Toungoo dynasty, was the ruling dynasty of Burma (Myanmar) from the mid-16th century to 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. But the largest empire in the history of Southeast Asia 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.

The kingdom entered a gradual decline due to the "palace rule" of its kings. Starting from the 1720s, the kingdom was beset with raids by the Meitei people of the Chindwin River, and a rebellion in Chiang Mai. Raids by the Meitei intensified in the 1730s, reaching increasingly deeper parts of central Burma. In 1740, the Mon people in Lower Burma began a rebellion, founding the Restored Hanthawaddy Kingdom. The Hanthawaddy armies captured Inwa in 1752 and ended the 266-year-old Toungoo dynasty.

The Ava Kingdom (Burmese: အင်းဝခေတ်, pronounced [ʔɪ́ɰ̃wa̰ kʰɪʔ]) was the dominant kingdom that ruled upper Burma (Myanmar) from 1364 to 1555. Founded in 1365, the kingdom was the successor state to the petty kingdoms of Myinsaing, Pinya and Sagaing that had ruled central Burma since the collapse of the Pagan Empire in the late 13th century.

Like the small kingdoms that preceded it, Ava may have been led by Bamarised Shan kings who claimed descent from the kings of Pagan. Scholars debate that the Shan ethnicity of Avan kings comes from mistranslation, particularly from a record of the Avan kings' ancestors ruling a Shan village in central Burma prior to their rise or prominence.
