Bayinnaung, who would go on to assemble the largest empire in the history of Southeast Asia, is crowned King of Burma.

Bayinnaung Kyawhtin Nawrahta was King of Burma from 30 April 1550 until his death in 1581, during the Toungoo dynasty. His reign is considered one of the most momentous in Burmese history, famously described as "the greatest explosion of human energy ever seen in Burma." During his rule, he assembled the largest empire in Southeast Asian history, which encompassed much of present-day Myanmar, as well as the Shan States, Lan Na, Lan Xang, Manipur, and the Ayutthaya Kingdom.

The Toungoo dynasty (Burmese: တောင်ငူမင်းဆက်, ; also spelt Taungoo dynasty, and also known as the Nyaungyan dynasty, was the ruling dynasty of Burma 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 and the Nyaungyan Restoration.

This is a list of the monarchs of Burma (Myanmar), covering the monarchs of all the major kingdoms that existed in the present day Burma (Myanmar). Although Burmese chronicle tradition maintains that various monarchies of Burma (Mon, Burman, Arakanese), began in the 9th century BCE, historically verified data date back only to 1044 CE at the accession of Anawrahta of Pagan. The farther away the data are from 1044, the less verifiable they are. For example, the founding of the city of Pagan (Bagan) in the 9th century is verifiable–although the accuracy of the actual date, given in the Chronicles as 849, remains in question–but the founding of early Pagan dynasty, given as the 2nd century, is not.
