The Khwarezmshahs and the Mongols, find themselves in a struggle for dominance at the beginning of the 1200s. Although Celaleddin does everything to warn his father, he would not be able to stop the Mongol invasion.

Nearly half a century had passed since the rise of the Crusaders, and life had turned into a harsh struggle for the Muslims dispersed in the region. Nureddin Zengi would fight alongside his father to stop this invasion and ensure that Urfa, which had been in the hands of the Crusaders for 50 years, would become a Muslim homeland again.
