 With the establishment of the Delhi Sultanate, Islam was spread across most parts of the Indian subcontinent.In the 14th century, the Khalji dynasty, under Alauddin Khalji, temporarily extended Muslim rule southwards to Gujarat, Rajasthan and the Deccan, while the Tughlaq dynasty temporarily expanded its territorial reach till Tamil Nadu.The break up of the Delhi Sultanate resulted in several Muslim sultanates and dynasties to emerge across the Indian subcontinent, such as the Gujarat Sultanate, Malwa Sultanate, the Bahmani Sultanate and the wealthy Bengal Sultanate, a major trading nation in the world.
