Pre-colonial map window (1820s–1885)

The late Konbaung dynasty reached its greatest extent under Bodawpaya and his successors, acquiring Arakan (1785), Manipur (1814) and Assam (1817) — an overextension that collided with British India. Three Anglo-Burmese wars dismembered it: the First (1824–26) cost Arakan, Assam, Manipur and Tenasserim (Treaty of Yandabo); the Second (1852) cost Lower Burma; and the Third (1885) ended with the fall of Mandalay, King Thibaw's exile and annexation on 1 January 1886. King Mindon's modernisation efforts (1853–78) had proved insufficient against British power.

Origins & foundation (modern state)

Political history & notable rulers

The parliamentary era (1948–62) saw AFPFL governments, elections in 1951–52, 1956 and 1960, ethnic insurgencies (Karen, Kachin, Shan) and Kuomintang incursions, plus the distinction of U Thant's election as UN Secretary-General (1961). On 2 March 1962 General Ne Win seized power, imposed the "Burmese Way to Socialism" — nationalisation, central planning and isolation — and ruled through a Revolutionary Council, then, under the 1974 constitution of the Socialist Republic of the Union of Burma, through the Burma Socialist Programme Party (BSPP). Protests were crushed (Rangoon University 1962, U Thant's funeral 1974). Economic collapse triggered the nationwide 8888 Uprising (1988); thousands were killed and General Saw Maung's SLORC junta seized power on 18 September 1988, renaming the country Myanmar in 1989 and refusing to honour the NLD's 1990 election landslide.

Economy, culture & religion

Once a leading rice exporter, Burma became one of the world's poorest countries under autarkic socialism. Theravada Buddhism (c. 88%) remained socially central, with monks repeatedly at the forefront of protest.

Peak & territorial extent

The Union inherited the colonial borders — Burma Proper plus the Shan, Kachin, Karen, Kayah, Chin and Rakhine frontier areas — c. 678,000 km²; the dataset's 813k figure reflects the 1820s Konbaung maximum.

Decline & end

The BSPP state effectively ended with the 1988 uprising and SLORC coup; the socialist republic was formally wound up as the junta rebranded the state (1989) and ruled until a managed transition in 2011.

Legacy & modern connections

The 1948–88 trajectory — ethnic federalism disputes, military dominance and autarkic failure — set the template for Myanmar's later crises, including the 2021 coup and ongoing civil war.
