The Civil Services Examination, explained clearly.
India is a parliamentary democracy with a well-established administrative system. Among the many bodies that recruit professional administrators, the Union Public Service Commission stands tall — and the Civil Services Examination it conducts is the most coveted of them all.
Historical Genesis of UPSC
Civil Servants for the East India Company used to be nominated by the Directors of the Company and trained at Haileybury College in London. Following Lord Macaulay's Report of the Select Committee of British Parliament, the concept of a merit-based modern Civil Service in India was introduced in 1854. A Civil Service Commission was set up in London and competitive examinations began in 1855.
Initially the examinations were conducted only in London. In 1864, Shri Satyendranath Tagore — brother of Rabindranath Tagore — became the first Indian to succeed. From 1922 onwards, the exam began to be held in India too — first in Allahabad, later in Delhi, with the setting up of the Federal Public Service Commission.
With the passing of the Government of India Act 1935, the Federal Public Service Commission was formed on 1 April 1937. With the inauguration of the Constitution of India on 26 January 1950, it was renamed the Union Public Service Commission by virtue of Article 378.
