who invaded the indian subcontinent around 1500 bce
Muslim rule started in parts of north India in the 13th century when the Delhi Sultanate was founded in 1206 CE by Central Asian Turks; though earlier Muslim conquests made limited inroads into modern Afghanistan and Pakistan as early as the 8th century. The Delhi Sultanate ruled the major part of northern India in the early 14th century, but declined in the late 14th century. This period also saw the emergence of several powerful Hindu states, notably Vijayanagara, Gajapati, Ahom, as well as Rajput states, such as Mewar. The 15th century saw the advent of Sikhism. The early modern period began in the 16th century, when the Mughal Empire conquered most of the Indian subcontinent. 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.
