"the "Gurjara Pratihara Empire" which continued in full glory for nearly a century, was the last great empire in Northern India before the Muslim conquest." This honour is accorded to the empire of Harsha by many historians of repute but without any real justification, for the Pratihara empire was probably larger, certainly not less in extent rivalled the Gupta Empire and brought political unity and its attendant blessings upon a large part of Northern India. But its chief credit lies in its succecessful resistance to the foreign invasions from the west, from the days of Junaid. This was frankly recognised by the Arab writers themselves.
