Akbar was the third Mughal emperor and undoubtedly the greatest. He crowned as the Mughal ruler in 1556 at the tender age of 14, when his father Humayun died suddenly. After Akbar consolidated his rule, he began constructing the Agra Fort, which coincided with the building of Humayun's tomb in Delhi . Though additions were made up until the rule of Shahjahan, who was Akbar's grandson. During the time of Akbar, the fort mainly served for military purpose, while by the time of Shahjahan it also served as a palace and court.
The lofty battlements of the Agra fort cast its protective shadow over the far stretching mansions of nobles and princes built along the riverfront. The magnificent towers, bastions and ramparts and majestic gateways symbolized the confidence and power of the third Mughal emperor. Of the nearly 500 Akbari buildings built in the Bengal and Gujarati traditions, only a few have survived, arrayed in a band on the riverfront.
