The Royal Commission on the superior Civil Services in India was set up less than the chairmanship of Lord Lee of Fareham by the British Government in 1923. With equal numbers of Indian & British members, the commission submitted its report in 1924, recommending setting up of a Public Service Commission. The Lee Commission put forward that 40% of future entrants should be British, 40% Indians directly recruited, and 20% Indians promoted from the provincial services. This led to the establishment of the first Public Service Commission on 1 October 1926 under the chairmanship of Sir Ross Barker. 

The Indian civil service (ESE) is a group of organizations and agencies tasked with the administration of the affairs of the Government of India. It comprises the Union Public Service Commission, which is the highest authority in all matters of recruitment and promotion, and various other government organizations that administer various public services such as police, customs, and taxation. The ESE also includes various non-governmental organizations that provide a wide range of social welfare programs and services to the Indian people. The ESE is an important part of India’s government structure because it provides a skilled and dedicated workforce to carry out the country’s administrative tasks.
