Timeline
From the chronicle accounts to the present, with what the sources actually establish kept separate from what they relate.
Entries marked this way are traditional or chronicle accounts. They are recorded here because they are part of how the past has been told, not because they are independently established.
Chronicle accounts
-
543 BCE ◇
Arrival of Vijaya
The Mahavamsa relates the landing of Prince Vijaya and the founding of the Sinhalese line. The chronicle was compiled around a thousand years later and historians read its opening sections as traditional narrative.

Anuradhapura founded
Traditionally dated to the reign of Pandukabhaya, who the chronicles credit with laying out the city, its reservoirs and its quarters.
Anuradhapura
-

Sanghamitta brings a cutting of the Bodh Gaya tree to Anuradhapura. Its tending has been documented continuously since.

The Pali Canon written down
At Aluvihare in Matale, the Tipitaka is committed to writing on palm leaf for the first time, during a period of famine and war that threatened the oral transmission.
-

-
477–495 CE
Kashyapa builds Sigiriya
The citadel, water gardens and rock paintings are made during an eighteen-year reign, after which the site reverts to monastic use.
-
993–1,017 CE
Chola conquest
Repeated invasions from South India culminate in Chola rule and the abandonment of Anuradhapura as capital after more than a millennium.
Polonnaruwa
-
1,070 CE
Vijayabahu I restores Sinhalese rule
Chola rule is ended and Polonnaruwa becomes the capital. The monastic ordination lineage, by then extinct on the island, is restored with monks brought from Burma.
-
1,153–1,186 CE
Reign of Parakramabahu I
The island is unified and the irrigation network rebuilt on a scale not attempted again before the modern period. Parakrama Samudra, Gal Vihara and the Polonnaruwa monuments date from this reign.
-
1,187–1,196 CE
Reign of Nissanka Malla
The inscriptions of this reign contain the earliest known use of the word Govigama. The fixed caste ranking often projected back onto earlier periods is not attested before this.
-
1,215–1,236 CE
Invasion of Magha and the drift south-west
Polonnaruwa is abandoned and the centre of population begins a long shift towards the wet zone of the south-west. The dry-zone irrigation civilisation contracts sharply.
Shifting capitals
-
1,341 CE
Coastal settlement recorded
Chronicle and inscriptional references to communities settling along the south-western coast. Migration into the island continued throughout this period and involved many groups.
-
1,412 CE
Kotte established
Parakramabahu VI makes Kotte his capital and briefly reunifies the island — the last ruler to do so before the colonial period.
Colonial rule
-
1,505 CE
Portuguese arrival
A Portuguese fleet reaches Colombo. Control of the cinnamon trade becomes the organising interest of European involvement for the next three centuries.
-
1,592 CE
Kandy becomes the capital
The Kandyan kingdom consolidates in the highlands and remains independent for a further 223 years.
-
1,658 CE
Dutch replace the Portuguese
The Dutch East India Company takes the maritime provinces and organises cinnamon production through compulsory service, binding the Salagama community to the work under quota and supervision.
-
1,753 CE
Higher ordination restored
Monks from Siam re-establish the ordination lineage at Kandy under Weliwita Saranankara, founding what becomes the Siyam Nikaya. Ordination is open to all.
-
1,764 CE
Ordination restricted to Govigama
A faction within the Siyam Nikaya restricts higher ordination to candidates of Govigama birth, cutting the maritime communities off from a valid lineage. The restriction has never been formally lifted.
-
1,796 CE
British take the maritime provinces
Control passes from the Dutch to the British East India Company, and in 1802 Ceylon becomes a Crown Colony.
-
1,800–1,810 CE
The Amarapura Nikaya founded
Salagama, Karava and Durava laymen finance expeditions to Burma to obtain ordination directly. By 1810 there are enough ordained monks to confer higher ordination in Sri Lanka — the first monastic lineage created by lay action rather than royal patronage.
-
1,815 CE
Fall of the Kandyan kingdom
The Kandyan Convention transfers sovereignty to the British Crown, with the chiefs retaining office and the state undertaking to protect Buddhism. The whole island is under one administration for the first time since 1215.
-
1,817–1,818 CE
Uva–Wellassa rebellion
A rising against British rule led by Keppetipola, suppressed with exceptional severity — crops destroyed, villages burned, the male population of parts of Uva devastated.
-
1,832 CE
Rajakariya abolished
The Colebrooke–Cameron reforms end compulsory service tenure. Abolition on paper and change on the ground were not the same: customary obligation and unequal landholding persisted long afterwards.
-
1,848 CE
Matale rebellion
A largely peasant revolt against new taxes, suppressed under martial law within weeks. The severity of the response led to a parliamentary inquiry in London.
-
1,864 CE
The Ramanna Nikaya founded
Ambagahawatte Saranankara establishes a third fraternity, again in response to caste restriction and to lapses in monastic discipline.
-
1,873 CE
The Panadura debate
A public disputation between Migettuwatte Gunananda Thera and Christian missionaries, widely regarded as a turning point in the Buddhist revival and in the confidence of Buddhist public argument.
-
1,911 CE
Caste last recorded in the census
After this year the census stops recording caste. Every population figure for any Sri Lankan community since is inference rather than measurement.
-
1,915 CE
The 1915 riots and internments
Communal violence is followed by mass arrests under martial law, including of temperance leaders later shown to be blameless. The episode radicalised much of the emerging Ceylonese leadership.
-
1,931 CE
Universal adult franchise
The Donoughmore constitution extends the vote to all adults — the first territory in Asia, and among the first anywhere outside Europe and the settler colonies, to do so.
Independent Sri Lanka
-
1,948 CE
Independence
Ceylon becomes independent on 4 February with D.S. Senanayake as Prime Minister. The Citizenship Act of the same year disenfranchised most Indian Tamil plantation workers.
-
1,956 CE
The Sinhala Only Act

The tsunami of 26 December kills more than 30,000 people on the island and displaces around half a million.
-
2,022 CE
Economic crisis and protests
Sri Lanka defaults on its sovereign debt in April. Sustained public protests lead to the resignation of the president in July.
