The people of Anatolia were forced to live under the threat of the Byzantine Empire while also suffering from a Mongolian invasion. The Kayı tribe, frontiersmen who remained in Söğüt, were in a constant state of red alert due to their location. When Ertuğrul Ghazi fell ill, a power vacuum emerged, leading to a struggle between his youngest son Osman—heroic and brave—and his uncle Dündar, a skilled statesman who had become the most successful politician after Ertuğrul. Dündar’s hunger for power grew after his brother’s sickness, and he was ready to defeat anyone who opposed him. Aygül, responsible for the women’s administration within the Kayı tribe, had loved Osman since childhood and wished to marry him. Bala Hanım, the daughter of Şeyh Edebali, sought to protect her people and, like Osman, prioritized their future. Their paths crossed, and they fell in love at first sight, but betrayals and plots created major obstacles. Osman fought both internally and externally to secure the Kayı tribe’s future and to reunite with Bala Hanım by overcoming these challenges.
