A historian has slammed the double standards employed in French schools which present Muslim conquerors as peaceful and brilliant, and Christians as backwards oppressors. Against the backdrop of terror attacks and rising Islamic extremism worldwide, teacher and author Barbara Lefebvre contends that education on Islam has “never been more necessary”. But the historian, who has published several books on the Holocaust, argues that textbooks’ sanitization of Muslim conquests and their presentation of an Islamic supremacist version of history is completely unhelpful.
