What if the Crusades’ history was told from an Arab perspective? In fact, in 2016 al-Jazeera TV did just that. It released a four-episode documentary on the Crusades, and the trailer introduced the subject in the following words: “In the history of conflict between East and West. The mightiest battle between Christianity and Islam; a holy war in the name of religion. For the first time, the story of the Crusades from an Arab perspective.” It is clear that the producers of the al-Jazeera documentary wanted their viewers to understand the Crusades as one out of many episodes in the continuous clash between two civilizations: East/Islam and West/Christianity. All three documentaries share the same plot about the clash of civilizations fuelled by the religious ideologies of holy war and jihad. The only difference is that the al-Jazeera documentary alleges to tell the story of the Crusades “for the first time” from an Arab perspective, which actually means that it is the turn of the Muslim Arabs to tell, not a different story, but rather the same story of the clash of civilisations.
