The Indian Civil Service (commonly known as the Imperial Civil Service or ICS) was the civil service of the Indian Government under the British colonial rule in India. This service still continues in the contemporary Civil Services of India, though these are now organised differently post-independence
The constitution provides for more Civil Services branches to be set up by giving the power to the Rajya Sabha to resolve by a two-thirds majority to establish new all-India services or central services. The Indian Forest Service and the Indian Foreign Service are the two services set up under this constitutional provision.
The running the administration of a vast and diverse country like India requires efficient management of its natural, economic and human resources. That, precisely, is the responsibility of the civil services. The country is managed through a number of Central Government agencies in accordance with the policy directions given by the ministries.
In spite of relatively contemporary careers like management and IT holding sway over the country's youth, the Civil Services of India have still not lost the vast popularity enjoyed by the old Indian Civil Service through the years since the time of the British Raj.
