Origins and founding

Capitals and territory

Colombo is the executive and judicial capital and largest city; Sri Jayawardenepura Kotte is the legislative capital. The unitary island state of ~22 million people is about 74% Sinhalese, with Sri Lankan Tamils, Moors and Indian Tamils as significant minorities; Buddhism (~70%) is the foremost religion, with Hindu, Muslim and Christian minorities.

Major rulers and key events

The UNP dominated until 1956, when S. W. R. D. Bandaranaike's SLFP passed the Sinhala Only Act, igniting communal tension (1958 riots); he was assassinated by a Buddhist monk in 1959. His widow Sirimavo Bandaranaike became the world's first female prime minister (1960). Her governments suppressed the 1971 JVP Marxist insurrection (~10,000 dead), nationalised plantations and, in 1972, made the country a republic named Sri Lanka, breaking the last constitutional ties to Britain. J. R. Jayewardene's 1977 landslide brought the 1978 constitution with a powerful executive presidency and South Asia's first liberalised economy. Tamil militancy — catalysed by "standardisation" university quotas and the LTTE's 1975 assassination of Jaffna's mayor — exploded after the July 1983 pogrom into a 26-year civil war. The Indo-Sri Lanka Accord (1987) brought the Indian Peace Keeping Force and a second JVP insurrection; Presidents Premadasa (assassinated 1993) and Kumaratunga followed; a 2002 Norwegian-mediated ceasefire collapsed, and under Mahinda Rajapaksa the army destroyed the LTTE in May 2009, killing its leader Prabhakaran — at a total war cost of 80,000–100,000 lives and war-crimes allegations. The 2019 Easter bombings (269 killed), the 2019–22 economic crisis (first-ever sovereign default on $51 billion), and the 2022 Aragalaya protests drove President Gotabaya Rajapaksa from office; in 2024 the left-wing Anura Kumara Dissanayake won the presidency and his NPP a two-thirds parliamentary majority.

Government, economy and culture

Unitary semi-presidential republic; tea, garments, tourism and remittances drive an economy with South Asia's highest human development. Sinhala and Tamil are official languages; the civil war produced a large Tamil diaspora.

Decline and end (current status)

Ongoing; post-war growth was interrupted by the 2019–2022 economic collapse, with recovery underway under the post-Aragalaya government.

Legacy and significance

Sri Lanka pioneered universal franchise (1931) and female head-of-government leadership (1960), but its Sinhala-only politics and the 1983–2009 civil war stand as a cautionary study of ethnic majoritarianism; its ports give it enduring Indian Ocean strategic weight.
