of British India was shifted from Calcutta to New Delhi, the last inner city of Delhi designed by Edwin Lutyens. After India's Independence from the British, New Delhi became the capital of the newly formed Republic of India. Mention in epics A long-standing tradition associates Delhi with Indraprastha and identifies the legendary city with the village Indarpat, which survived until the early 20th century within the Purana Qila. There is no tangible archeological evidence, however, which links the excavated 'painted greyware' at Purana Qila with the Bharata Khanda site.The legendary ancient city of Indraprastha is mentioned in the ancient Indian epic Mahabharata probably compiled between the 3rd century BCE and the 3rd century CE, with the oldest preserved parts not much older than around 400 BCE. There was Ochre Coloured Pottery culture in Red fort area which began around c.2000 BCE according to carbon dating. Around c.1200 BCE the region was inhabited by people of Painted Grey Ware culture which corresponds to Vedic Period. Significant prehistoric sites in Delhi include Anangpur (in the Badarpur region), as well as Harappan excavations near Narela and Nand Nagari. Medieval period Tomaras Anangpal Tomar founded Delhi in 1052. A VS 1383 inscription in Delhi Museum confirms the founding of Delhi by the Tomars. He established the Tomar Dynasty of Delhi in the early 8th century and built his capital at the Anangpur village in Haryana. The Anangpur Dam was built during his reign; the Surajkund during the reign of his son Surajpal. Chauhan The Rajput Chahamana (Chauhan) kings of Ajmer conquered Lal Kot in 1180 and renamed it Qila Rai Pithora. The Chauhan king Prithviraj III was defeated in 1192 by Muhammad Ghori in the Second Battle of Tarain, solidifying Muslim presence in northern India and shattering Rajput power in the Indo-Gangetic Plain. Late Medieval period (13th-16th centuries CE) Delhi Sultanate From 1206, Delhi became the capital of the Delhi Sultanate under the Slave Dynasty. The first Sultan of Delhi, Qutb-ud-din Aybak, was a former slave who rose through the ranks to become a general, a governor and then Sultan of Delhi. Qutb-ud-din started the construction of the Qutub Minar, a recognisable symbol of Delhi, to commemorate his victory but died before its completion. In the Qutb complex he also constructed the Quwwat-al-Islam (might of Islam), which is the earliest extant mosque in India. He was said to have destroyed twenty-seven Jain temples initially
