Karen Armstrong is a former nun who writes broadly on political and religious issues including the crusades and Islam. As a well known critic of modern western attitudes towards Islam, Armstrong has often sought to draw attention to what she sees as historical injustices carried out by westerners in the East. She lists the crusades among these injustices. For example, in her work, Islam: A Short History, she writes:
It was, for example, during the Crusades, when it was Christians who had instigated a series of brutal holy wars against the Muslim world, that Islam was described by the learned scholar-monks of Europe as an inherently violent and intolerant faith, which had only been able to establish itself by the sword. The myth of the supposed fanatical intolerance of Islam has become one of the received ideas of the West. [pp. 179-180]
Of all of those currently writing on the crusades, her work is probably among the most popular and well known to the general public. In my case, I have had history students who have read her books in other settings come to me confused about apparent contradictions between what they were learning in my class and what they read in her book. I also once had a member of the general public, after reading a guest column I once wrote for the Florida Times Union, email me for the same reason, seeking clarification. The reason for these contradictions is because I have been trained as a medieval historian and work within the current dominant historiography of the crusades, much of which is decidedly at odds with some of the claims Armstrong makes in her works.
