Vijayabahu I of Polonnaruwa
King of Sri Lanka
1030 CE to 1110 CE
Vijayabahu I (born, Prince Keerthi ) (ruled 1055–1110) is a medieval king of Sri Lanka.
Born to a royal bloodline, he grows up at a time when part of the country is occupied by invaders from the Chola Kingdom of Tamilakam.
He assumes rulership of the Ruhuna principality in the southern parts of the country in 1055.
Following a seventeen-year-long campaign, he successfully drives the Chola out of the island in 1070, reuniting the country for the first time in over a century.
During his reign, he re-establishes Buddhism in Sri Lanka and repairs much of the damage caused to infrastructure during the wars.

Maritime South Asia (964 – 1107 CE): Chola Expansion, Western Chalukyas, and Polonnaruwa’s Ascent
Maritime South Asia includes peninsular India south of the Narmada River (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, Maharashtra, Goa, Dadra and Nagar Haveli and Daman and Diu, southern Odisha, southern Chhattisgarh), Sri Lanka, Lakshadweep, the Maldives, and the Chagos Archipelago.
-
Anchors: the Tamil plains, Deccan plateau, Kerala backwaters, Sri Lanka’s dry and wet zones, and the Maldives–Chagos island chains.
Climate and Environmental Shifts
-
Monsoons remained reliable during the later Medieval Warm Period, supporting agricultural expansion in Tamil Nadu, Kerala, and Andhra.
-
Occasional droughts affected the Deccan interior, but extensive irrigation tanks and Kerala’s backwaters cushioned the impact.
-
Sri Lanka shifted from Anuradhapura toward Polonnaruwa, continuing to invest in reservoirs and canals.
-
The Maldives were increasingly tied into South Indian trade circuits under Chola influence, though still reliant on coconuts and fisheries; Lakshadweep and Chagos remained small-scale subsistence islands.

Long-Term Significance
By 1107, Cholas dominated peninsular India and maritime South Asia; Sri Lanka recovered autonomy; island chains were drawn into Indian Ocean circuits.
King Vijayabahu I drives the Chola out of Sri Lanka in CE 1070.
Considered by many as the author of Sinhalese freedom, the king recaptures Anuradhapura but rules from Polonnaruwa, slightly less than one hundred kilometers to the southeast.
During his forty-year reign, Vijayabahu I (1070-1110) concentrates on rebuilding the Buddhist temples and monasteries that had been neglected during Chola rule.
He leaves no clearly designated successor to his throne, and a period of instability and civil war will follow his rule until the rise of King Parakramabahu I, known as the Great (1153-86).
