Colombo is the commercial capital and largest city of Sri Lanka, situated on the west coast of the island at the mouth of the Kelani River. As of the 2021 national census, the Colombo Metropolitan Region had a population of approximately 5.6 million, making it the most populous urban area in the country. The city serves as a major financial, cultural, and administrative centre, hosting the headquarters of numerous multinational corporations, state institutions, and the official residence of the President of Sri Lanka.
Etymology
The name "Colombo" derives from the Sinhalese "Kola-amba" meaning "harbor with leafy trees," which was later adapted by Portuguese and Dutch colonial powers to the present form.
History
- Pre‑colonial period: Archaeological evidence indicates human settlement in the area dating back to the 5th century BC. The city was part of the ancient Kingdom of Kotte.
- Colonial era: Portuguese explorers arrived in 1505 and established a fort, naming the settlement "Colombo." The Dutch seized control in 1656, expanding the fortifications and establishing a trading post. The British captured Colombo in 1796, making it the administrative capital of Ceylon (now Sri Lanka) in 1815.
- Independence and modern era: Following Sri Lanka’s independence in 1948, Colombo remained the principal urban centre. In 1978, the official legislative capital was moved to Sri Jayawardenepura Kotte, but Colombo retained its economic primacy.
