The Ceylon Civil Service, popularly known by its acronym CCS, was the premier civil service of the Government of Ceylon under British colonial rule and in the immediate post-independence period. Established in 1833, it functioned as part of the executive administration of the country to various degrees until Ceylon gained self-rule in 1948. Until it was abolished on 1 May 1963 it functioned as the permanent bureaucracy or secretariat of Crown employees that supported the Government of Ceylon.
Much of the duties of the CCS was taken over by the much larger Ceylon Administrative Service (CAS) which was created absorbing all executive management groups such as the CCS officers and the Divisional Revenue Officers' Service, was to be established with five grades. It was renamed following the declaration of the republic in 1972 as the Sri Lankan Administrative Service which is now the key administrative service of the Government.
The origins of the service dates back to 1798, when the Secretary of State for the Colonies appointed several officers to assist the British Governor of Ceylon in the administration of the coastal areas. After Ceylon became a crown colony in 1802, an advisory council was formed to assist the Governor, made up of the Colonial Secretary, Chief Justice, Commander of Troops and two other members. Colonial Secretary and the other two members where civil servants. Once the Kingdom of Kandy was taken over by the British in 1815, a British Resident Sir John D'Oyly was appointed along with a Board of Commissioners who were civil servants.
Following the Colebrooke-Cameron Commission recommendations administration of the coastal provinces and the former Kingdom of Kandy were merged and administration formed into one. Thus a central civil service, known as the Ceylon Civil Service was formed in 1833 to handle the administration of the island under the directive of the Governor. As per the Colebrooke-Cameron Commission, the Executive Council of Ceylon and the Legislative Council of Ceylon was formed. Each had members of the Ceylon Civil Service as officials. Most of these were CCS officers including Colonial Secretary and Colonial Treasure. Government Agents were appointed from senior CCS officers to administrate each province.
