Agra was the first capital city of Mughal Empire in India. The golden age of the city began with the Mughals. It was known then as Akbarabad and remained the capital of the Mughal Empire under the padshahs (emperors) Akbar, Jahangir and Shah Jahan. Akbar made it the eponymous seat of one of his original twelse subahs (imperial top-level provinces), bordering (Old) Delhi, Awadh (Oudh), Allahabad, Malwa and Ajmer subahs. Shah Jahan later shifted his capital to Shahjahanabad (Old Delhi) in the year 1649 during his reign, but his son Aurangzeb moved the capital back to Akbarabad, usurping his father and imprisoning him in the Fort there. Akbarabad remained the capital of India during the rule of Aurangzeb until he shifted it to Aurangabad in the Deccan in 1653.
