During the thirty years of his rule Shahjahan enjoyed the supreme power as the head of the state. There was none to challenge his power. The huge wealth and treasure amassed by his grandfather and father was utilized by Shahjahan for beautification of city and constructing magnificent buildings and tombs.
Again, the incidence of rebellion during Shahjahan’s reign was not at all high. Shahjahan’s reign would be remembered, if not for anything else, only for the architectural advancement. On the grounds as mentioned above some historians called Shahjahan’s reign as the golden period of the Mughal day in the history of India.
Of course in the opinion of modern historians Shahjahan failed to basic weaknesses of the Mughal administration and thus the epithet of the ‘golden age’ is not applicable to Shahjahan’s reign.
