"Not surprisingly, nationalism was replaced by a form of militant Hinduism, and the communal atmosphere in Indian politics in the late 1930s and the 1940s tended to vitiate the study of ancient and medieval history. The Gupta period became the ‘Golden Age’ largely because it was the period of renascent Hinduism. Many of the ills of India were ascribed to ‘the Muslim invasions and rule’. It was maintained that Hinduism in its Sanskritic form was the essential culture of India, and other forces were in a sense an intrusion."
