Akbar ascended the throne in 1556 at age 13 and established the largest empire after Ashoka, with his capital originally at Agra. He built great architectural monuments during his reign, including the grand Red Fort and city of Fatehpur Sikri. Fatehpur Sikri was built from red sandstone in the local style and included secular palaces like the Jodha Bai Palace and religious buildings like the Friday Mosque. Akbar's architectural legacy demonstrated his power and vision.
