India, July 16 -- The National Council for Education Research and Training (NCERT) has revised the Class 8 social science textbook, pointing out many instances of "religious intolerance" during the Delhi Sultanate and the Mughal period.

The book, which introduces the students to the Sultanate and the Mughal periods, describes Babur as a "brutal and ruthless conqueror, slaughtering entire populations of cities", Akbar's reign as a "blend of brutality and tolerance", and Aurangzeb, who destroyed temples and gurdwaras, The Indian Express reported.

The NCERT said it has includeda disclaimer with the revisions in a "Note on Some Darker Periods in History" that "no one should be held responsible today for events of the past".
