Historical Eras
The major periods of {country}’s history at a glance.
Ancient Kingdoms
500 BCE – 1070
Sinhalese settlers from northern India established the island's first great civilization, centered on Anuradhapura from around 200 BCE. Buddhism, introduced in the 3rd century BCE during the reign of the Mauryan emperor Ashoka's emissary Mahinda, became the cornerstone of Sinhalese identity and statecraft. The era was defined by sophisticated hydraulic engineering, Buddhist chronicle-writing, and dynastic conflicts with South Indian invaders, including the legendary King Dutugamunu's victory over the Chola king Elara around 161 BCE.
Polonnaruwa & Decline
1070 – 1400
Following Chola occupation, King Vijayabahu I reunified the island and shifted the capital to Polonnaruwa, which flourished under Parakramabahu I in the 12th century as a center of Buddhist art, architecture, and expansive irrigation works. The kingdom fragmented after 1200 amid internal strife and further South Indian incursions. By the 14th century, a Tamil dynasty established the Kingdom of Jaffna in the north, permanently altering the island's political and ethnic geography.
European Colonial Era
1505 – 1815
Portuguese arrival in Colombo in 1505 initiated over three centuries of European dominance, during which successive colonial powers suppressed Buddhism and promoted Christianity. The Dutch expelled the Portuguese in 1658, controlling coastal territories until Britain assumed power in 1796 and declared Ceylon its first Crown Colony in 1802. British forces completed their conquest with the fall of the Kingdom of Kandy in 1815, extinguishing the last independent Sinhalese polity.
British Crown Colony
1815 – 1948
Under consolidated British rule, Ceylon was unified administratively and transformed economically through plantation agriculture, with Tamil laborers imported from South India to work tea and rubber estates. The British progressively extended political participation, culminating in universal suffrage under the Donoughmore Constitution of 1931. A growing nationalist movement leveraging these constitutional reforms ultimately secured full independence for Ceylon on February 4, 1948.
Ceylon / Early Independence
1948 – 1983
Independent Ceylon maintained democratic governance through successive elected governments, though communal tensions escalated sharply after Solomon Bandaranaike's 1956 election on a platform of Sinhalese nationalism and the Official Language Act, which marginalized Tamil speakers. The country adopted a new republican constitution in 1972 and renamed itself Sri Lanka. Tamil political grievances deepened through this period, leading to the formation of the Liberation Tigers of Tamil Eelam in 1976.
Civil War & Modern Era
1983 – present
The anti-Tamil pogrom of July 1983 ignited a devastating civil war between the Sri Lankan state and the LTTE, marked by four escalating Eelam Wars, suicide bombings, and the assassination of President Premadasa in 1993. The government declared military victory over the LTTE in May 2009, ending 26 years of armed conflict at enormous human cost. Post-war Sri Lanka has grappled with reconciliation, accountability for wartime abuses, economic development, and the political turbulence that culminated in the popular uprising of 2022.
