Historical Trajectory
Phase I: Rise
Parakramabahu VI founded the Kingdom of Kotte in 1412 with support from Ming China. Capitalising on this alliance, he extended control across Sri Lanka by conquering the Jaffna kingdom and the Vanni principalities, briefly uniting the island under a single Sinhalese administration. His forces also launched a punitive expedition against the Vijayanagar dynasty and seized a strategic port, establishing Kotte as the dominant political power on the island.
Phase II: Zenith
At its height in the 15th century, the Kingdom of Kotte held sway over much of Sri Lanka, commanding tribute from former rival polities and projecting military power onto the Indian mainland. The capital, Kotte, functioned as a centre of Sinhalese Buddhist culture and royal patronage. The kingdom's diplomatic ties with Ming China bolstered its international standing and provided a counterweight to regional threats from South Indian powers.
Phase III: Decline
The kingdom's authority eroded sharply in the 16th century as the rival Kingdom of Sitawaka and Kingdom of Kandy chipped away at its territory. Portuguese intervention deepened the crisis: King Dom João Dharmapala ceded his realm to Portugal, triggering the Sinhalese-Portuguese War that effectively dissolved Kotte. The remaining territories were absorbed into Sitawaka and Kandy, while Jaffna was reconquered by Kanakasooriya Cinkaiariyan, completing the kingdom's disintegration by 1597.
