Jerusalemfell into the hands of the crusaders at the end of the eleventhcentury. The fall of the city actually reflected the internalproblemof Muslim civilisation. It was almostnine decades later that Jerusalemwas successfully recapturedby Ṣalāḥal-Dīn al-Ayyūbī(d. 1193). Some scholars have aview thatṢalāḥal-Dīn’s victory was in fact an outcome of Sunni revival triggered by the spiritual thoughtor taṣawwufofAbū Ḥāmid al-Ghazālī (d. 1111).This viewbecomes even more interesting when examinedwith the theory of civilisationdeveloped by Malik Bennabi (d. 1973), a twentiethcentury Algerian Muslim thinker. Some scholars have discussed Malik Bennabi’s thought, but it seems few, if any, have used his theoryto interpret certain historical chapter. This article attempts to re-read the history of the struggle for Jerusalemin the crusading period through Bennabi's perspectiveand discussesthe importance of al-Ghazālī in this struggle.
