History
Parts of present-day Western Province were part of the pre-colonial Kingdom of Kotte. The province then came under Portuguese, Dutch and British control. In 1815 the British gained control of the entire island of Ceylon. They divided the island into three ethnic based administrative structures: Low Country Sinhalese, Kandyan Sinhalese and Tamil. The Western Province was part of the Low Country Sinhalese administration. In 1833, in accordance with the recommendations of the Colebrooke-Cameron Commission, the ethnic based administrative structures were unified into a single administration divided into five geographic provinces. The districts of Chilaw, Colombo, Kalutara, Puttalam, Seven Korales, Three Korales, Four Korales and Lower Bulatgama formed the new Western Province. Chilaw District, Puttalam District and Seven Korales were transferred to the newly created North Western Province in 1845. Three Korales, Four Korales and Lower Bulatgama were transferred to the newly created Sabaragamuwa Province in 1889.It is planned to create a planned Megacity under the Western Region Megapolis Plan in the Western Province designed by Surbana.
