Those who you are refferring to as Great Mughal emporers, most of them were bloody tyrants who had unleashed a string of murder, terror, rapes and plundering of temples. ( not to mention the killings and imprisonment of their own siblings and parents)
They did NOT bring along an era of great new architecture, but in most of the places destroyed many beautiful monuments. Indeed, you yourself are at a loss ( for almost 12th century to 1875, you can mention only Jama Masjid, Red Fort (Taj Mahal is a disputed heritage ) ) Contray to your statement Aurangazeb was not able to win much teritorry, was an utter failure against Chatrapati Shivaji, and finally died with a will to destroy the Maratha kingdom
