Delhi finds prominent reference right from the times of the epic Mahabharata. Its control passed from one ruler/dynasty to another, beginning with the Mauryas, Pallavas, Guptas of Central India, and then to the Turk and Afghan during the 13th to 15th centuries, and finally to the Mughals in the 16th century. In the latter half of the 18th century and early 19th century, the British rule was established in Delhi. In 1911, Delhi became the centre of all activities after the capital was shifted from Kolkata. It was made a Union Territory in 1956. Lying in the northern part of the country, Delhi is surrounded by Haryana on all sides except the east, where it borders with Uttar Pradesh. The 69th Constitutional amendment is a milestone in Delhi's history, as it got a Legislative Assembly with the enactment of the National Capital Territory Act, 1991.
