Delhi was under the Maurya Empire. Remnants of seven chief cities have been discovered in Delhi. Delhi has seen the rise and fall of many empires, which have left behind a surplus of monuments that are the magnificence and glory of past ages. In the 13th century, Delhi fell into the hands of the Delhi Sultanates and subsequently it came under the dominion of the Mughal Empire. Delhi passed on to the hands of the British in 1803 AD.

The actual enforcement of the legislation came in 1993.
