Factual error: At the end, Jamiel climbs one of the palace towers and, as a sign of victory, hoists the Arabian flag. Only thing: Baghdad was located in Persia (today's Iran and Iraq), not Arabia; and the shown flag, the green 'shahada', did not appear until the late 18th century. The ancient Persian flag, as far as I could find out, showed a star.
