Muslim rule started in parts of north India in the 13th century when the Delhi Sultanate was founded in 1206 CE by the Central Asian Turks. The Delhi Sultanate ruled the major part of northern India in the early 14th century, but declined in the late 14th century when several powerful Hindu states such as the Vijayanagara Empire, Gajapati Kingdom, Ahom Kingdom, as well as Rajput dynasties and states, such as Mewar dynasty, emerged. The 15th century saw the emergence of Sikhism. In the 16th century, Mughals came from Central Asia and gradually covered most of India. The Mughal Empire suffered a gradual decline in the early 18th century, which provided opportunities for the Maratha Empire, Sikh Empire and Mysore Kingdom to exercise control over large areas of the subcontinent.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During what century did the Mughal empire decline?
early 18th century
