Pan-Islamism is dormant – yet we have to reckon with the possibility that the sleeper may awake if ever the cosmopolitan proletariat of a “Westernized” world revolts against Western domination and cries out for anti-Western leadership. That call might have incalculable psychological effects in evoking the militant spirit of Islam – even if it had slumbered as long as the Seven Sleepers – because it might awaken echoes of a heroic age. On two historic occasions in the past, Islam has been the sign [under] which an Oriental society has risen up victoriously against an Occidental intruder. Under the first successors of the Prophet, Islam liberated Syria and Egypt from a Hellenic domination which had weighed on them for nearly a thousand years. Under Zangi and Nur-ad-Din and Saladin and the Mamluks, Islam held the fort against the assaults of Crusaders and Mongols. [In] the present situation of mankind […] Islam might be moved to play her historic role once again. Absit omen.
