In the final episode, Rageh Omaar explains how the collapse of the Ottoman Empire following the First World War left problems that still exist in Europe and the Middle East. Rageh also reveals how struggles at the heart of the Ottoman story have recently been reignited on the streets the Ottomans once ruled, from Syria to Turkey.

It underwent a social revolution led by military commander and secular visionary Mustafa Kemal Ataturk. So why is Ottomanism back on the political agenda? And why are many politicians in the West hoping that Turkey can provide a role model as a modern, Islamic democracy?
