I want to know the answer to the following question:
What group founded the Delhi Sultanate in the 13th century?
All the background I'm provided with is that "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.". Is that enough to answer the question?
