History of UPSC
The history of the Union Public Service Commission (UPSC) reflects India’s journey toward establishing a fair, transparent, and merit-based system for recruiting civil servants. Before independence, appointments to senior government positions were largely influenced by British administrative policies, and competitive examinations were conducted mainly in England, making it difficult for most Indians to participate.
Over the years, several reforms were introduced to create an independent recruitment system that would select capable individuals based on merit rather than privilege. These reforms eventually led to the establishment of the Union Public Service Commission, which today serves as India’s premier constitutional recruitment agency.
Since its formation, UPSC has played a vital role in strengthening the Indian administrative system by ensuring that recruitment to civil services remains impartial, transparent, and based solely on merit.
Evolution of UPSC
The development of UPSC took place over several decades through important constitutional and administrative reforms.
1854 – Introduction of Competitive Civil Service Examination
The British Government introduced an open competitive examination for recruitment to the Indian Civil Services (ICS) based on the recommendations of the Macaulay Committee. However, these examinations were conducted only in London, making it difficult for Indian candidates to participate.
1924 – Lee Commission Recommendations
The Lee Commission, officially known as the Royal Commission on the Superior Civil Services in India, recommended the creation of an independent Public Service Commission to ensure fair recruitment and reduce political influence in civil service appointments.
These recommendations became the foundation for India’s modern civil service recruitment system.
1926 – Establishment of the First Public Service Commission
On 1 October 1926, the first Public Service Commission was established in India under the chairmanship of Sir Ross Barker.
Although its powers were limited, it marked the beginning of an independent recruitment process for government services.
1935 – Government of India Act
The Government of India Act, 1935 significantly strengthened the recruitment system by providing for the establishment of:
- Federal Public Service Commission
- Provincial Public Service Commissions
- Joint Public Service Commissions
This Act laid the groundwork for the present-day UPSC and State Public Service Commissions.
1950 – Formation of the Union Public Service Commission
After India adopted its Constitution on 26 January 1950, the Federal Public Service Commission was renamed the Union Public Service Commission (UPSC) under Article 315 of the Constitution of India.
Since then, UPSC has functioned as an independent constitutional body responsible for recruiting officers for various Central Government services through a transparent and merit-based selection process.
