After the death of Ertugrul, the reins of rule over the Turkish lands passed to his heir, the 23-year-old Osman I Ghazi. The youth inherited the territory of Phrygia, but this ambitious leader was not satisfied: he dreamed that the fame of the power of his homeland would resound around the world. Despite his limited experience, the young ruler set about expanding his country's borders with success: he annexed a significant part of Byzantium, ensuring the Turks access to the Sea of Marmara and the Black Sea, and he united with Muslims who had fled from the Mongols. The bravest warrior of his army was Osman himself: he was always in the thick of the action, setting a worthy example for his brothers in arms. Through the efforts of this sultan, Turkey would become a great empire that would bear his name. But that would come years later, for now he faces many trials ahead: betrayal by close people, new conquests and losses, the intrigues of envious rivals, and the greatest love of his life.
