The Mughal Empire ( , ; مغلیہ سلطنت, ; self-designation: گوركانى, ), was an imperial power which ruled most of the Indian subcontinent from the early 16th to the mid-19th centuries . At the height of its power, around 1700, it controlled most of the subcontinent and parts of what is now Afghanistan. Its population at that time has been estimated as between 110 and 130 million, over a territory of over 4 million km² (1.5 million mi²). Following 1725 it declined rapidly. Its decline has been variously explained as caused by wars of succession, agrarian crises fuelling local revolts, the growth of religious intolerance and British colonialism. The last Emperor, Bahadur Shah II, whose rule was restricted to the city of Delhi, was imprisoned and exiled by the British after the Indian Rebellion of 1857.

The classic period of the Empire starts with the accession of Akbar the Great in 1556 and ends with the death of Aurangzeb in 1707, although the Empire continued for another 150 years. During this period, the Empire was marked by a highly centralized administration connecting the different regions of India. All the significant monuments of the Mughals, their most visible legacy, date to this period.
