Great Rebellion of 1817–1818

The Great Rebellion of 1817–1818 (Sinhala: ඌව වෙල්ලස්ස මහා කැරැල්ල), also known as the 1818 Uva-Wellassa Rebellion (after the two places where it had started), was the third Kandyan War in the Uva and Wellassa provinces of the former Kingdom of Kandy, which is today the Uva province of Sri Lanka. The rebellion started against the British colonial government under Governor Robert Brownrigg, three years after the Kandyan Convention ceded the Kingdom of Kandy to the British Crown.
