Ruins of once grand temples are strewn around north India.

 Ruins of once grand temples are strewn around north India. Almost all of them date back to what is variously known in prevalent textbooks as the 'medieval period' of Indian history. British authors of Indian history called it the 'Muslim' period of Indian history. Historians associated with the Indian History Congress routinely gave lectures on how some other name needed to be used but still, the Indian History Congress-- dominated by historians from Aligarh and Delhi-- has continued to divide its scholarly efforts into the 'ancient', 'medieval' and 'modern' period. Almost all the departments of history in the universities of India too are divided in the same manner. The British had called the ancient period as the Hindu period, the medieval period as the Muslim period and the modern period was associated with  British rule.
