"India south of the Vindhyas was under Hindu rule in the 13th century. Even in North India during the same century, there were powerful kingdoms not yet subjected to Muslim rule, or still fighting for their independence… Even in that part of India which acknowledged the Muslim rule, there was continual defiance and heroic resistance by large or small bands of Hindus in many quarters, so that successive Muslim rulers had to send well-equipped military expeditions, again and again, against the same region… As a matter of fact, the Muslim authority in Northern India, throughout the 13th century, was tantamount to a military occupation of a large number of important centres without any effective occupation, far less a systematic administration of the country at large. .... The Khalji empire rose and fell during the brief period of twenty years (A.D 1300-1320). The empire of Muhammed bin Tughlaq… broke up within a decade of his accession (A.D. 1325), and before another decade was over, the Turkish empire passed away for ever… Thus barring two every short-lived empires under the Khaljis and Muhammad bin Tughlaq… there was no Turkish empire in India. This state of things continued for nearly two centuries and a half till the Mughals established a stable and durable empire in the second half of the sixteenth century A.D."
