Pagan Kingdom
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 granted independence in 1948. Following a coup d'état in 1962, it became a military dictatorship under the Burma Socialist Programme Party.
