The Crusades: The Authoritative History of the War for the Holy Land

by Thomas Asbridge

Islamism is the polar opposite of Arab Nationalism in terms of ideology–espousing the notion that Islam must be governed as a theocracy. Nonetheless, Islamists have, if anything, been even more strident in their attempts to establish spurious links between the medieval crusades and the modern world. Given its spiritual perspective, Islamist propaganda presents the crusades as aggressive religious wars waged against the Dar al-Islam (Islamic territory), the only response to which can be violent physical jihad. One of the most influential Islamist ideologues, Sayyid Qutb (who was executed in Egypt for treason in 1966), described western imperialism as a ‘mask for the crusading spirit’, stating that ‘the crusader spirit runs in the blood of all westerners’. He also declared that there was a conspiracy of ‘international Crusaderism’ behind the West’s Levantine interventions, citing Allenby’s supposed reference to the medieval crusades as proof.
