The city has experienced different phases of different dynastic powers since then where several layers of human development were added supporting in making a city which can be said to be built by people assembled from all directions of its location. The Mamluks developed Mehrauli, the Khiljis built their fort at Siri, the Tughlaqs built their cities at Tughlaqabad and Jahanpahan & later also at Ferozabad, the Suris at Sher-Garh and the Mughals gave orders first from DinPanah (then Jahangir shifted his capital to Agra) and then later from Shanjahanabad during the reign of Shahjahan which is now called to as the Old City of Delhi after which the seat of British Indian Crown was shifted to Delhi in 1911 from Kolkata where they developed the modern version of Delhi currently named as New Delhi or as Lutyens Delhi by some till 1947 since when it became the national capital of the Republic of India. The city has a long history and has been historically one of the most cosmopolitan cities of India both culturally & inter-nationally.
The city development authority shall understand the significance and importance of integrating social planning along with physical planning which will eventually bring out a more streamlined development of natural system. The physical aspects are also needed to be checked and tested with an emphasis test by means of setting a hierarchy based on inter-dependent system of the urban ecosystem. The quality of life of the citizens shall be given a wider canvas to look beyond integration of information technology into their lives. Delhi presents a live example of a city with different stages of a city’s life and if the planning fraternity understands it well then the planning process for cities can be perceived through a much more magnified vision.
