How would it be possible to create Shiite-majority populaces in Egypt, Middle East, North Africa and Sudan while keeping Albania, Bosnia, Caucasus, Central Asia, Indian subcontinent, southeast Asia and Turkey Sunni?
Keep the Fatimid Caliphate in Egypt and wank it all the way from Argelia to the levant and sudan but keep all the rest of the Muslim world sunni. And make shure they convert the majority of their people to ismaeli shia.
