It dwells on the most remarkable dynasties ever to lead the Muslim world - the Abbasids of Baghdad, the Umayyads of Damascus and Cordoba, the Merinids of Fez, the Ottomans of Istanbul, the Mughals of India and the Safavids of Isfahan - and some of the most charismatic leaders in Muslim history, from Saladin in Cairo and mighty Tamerlane of Samarkand to the poet-prince Babur in his mountain kingdom of Kabul and the irrepressible Maktoum dynasty of Dubai.
