The planning and design of the Red Fort represents a culmination of architectural development initiated in 1526 AD by the first Mughal Emperor and brought to a splendid refinement by Shah Jahan with a fusion of traditions: Islamic, Persian, Timurid and Hindu. The innovative planning arrangements and architectural style of building components as well as garden design developed in the Red Fort strongly influenced later buildings and gardens in Rajasthan, Delhi, Agra and further afield. The Red Fort has been the setting for events which have had a critical impact on its geo-cultural region.
