It is the largest country in Mainland Southeast Asia, and has a population of about 54 million as of 2017. Myanmar is bordered by Bangladesh and India to its northwest, China to its northeast, Laos and Thailand to its east and southeast, and the Andaman Sea and the Bay of Bengal to its south and southwest. The country’s capital city is Naypyidaw, and its largest city is Yangon (Rangoon).
Early civilisations in the area included the Tibeto-Burman-speaking Pyu city-states in Upper Myanmar and the Mon kingdoms in Lower Myanmar. In the 9th century, the Bamar people entered the upper Irrawaddy valley, and following the establishment of the Pagan Kingdom in the 1050s, the Burmese language, culture, and Theravada Buddhism slowly became dominant in the country. The Pagan Kingdom fell to Mongol invasions, and several warring states emerged. In the 16th century, reunified by the Taungoo dynasty, the country became the largest empire in the history of Southeast Asia for a short period.
The early 19th-century Konbaung dynasty ruled over an area that included modern Myanmar and briefly controlled Manipur and Assam as well. The British East India Company seized control of the administration of Myanmar after three Anglo-Burmese Wars in the 19th century, and the country became a British colony. After a brief Japanese occupation, Myanmar was reconquered by the Allies and gained independence in 1948. Following a coup d’état in 1962, it became a military dictatorship under the Burma Socialist Programme Party.
Independence (1948–1962)

On 4 January 1948, the nation became an independent republic, under the terms of the Burma Independence Act 1947. The new country was named the Union of Burma, with Sao Shwe Thaik as its first president and U Nu as its first prime minister. Unlike most other former British colonies and overseas territories, Burma did not become a member of the Commonwealth. A bicameral parliament was formed, consisting of a Chamber of Deputies and a Chamber of Nationalities, and multi-party elections were held in 1951–1952, 1956 and 1960.
The geographical area Burma encompasses today can be traced to the Panglong Agreement, which combined Burma Proper, which consisted of Lower Burma and Upper Burma, and the Frontier Areas, which had been administered separately by the British.
