Origine of Name Delhi
The name Delhi may be derived from the word 'Dhillika', though there are other theories. According to Satyarth Prakash (1875) of Swami Dayanand Saraswati, Raja Dhilu founded ancient Delhi in 800 BC, however it is not supported by any older texts. It was the name of the first medieval township of Delhi, located on the southwestern border of the present Delhi, in Mehrauli. This was the first in the series of seven medieval cities. It is also known as Yoginipura, that is, the fortress of the yoginis. It gained importance during the time of Ananga Pala Tomar. In the 12th century, the city was included in the dominions of Prithviraj Chauhan. Pasanaha Chariu of Vibudh Shridhar (VS 1189-1230) an Apabhramsha writer, provides the first reference to the legend of the origin of the name Dhilli for Delhi.
