After ten years in Söüt, a Mongol-controlled Selçuk state, Erturul faces many Mongol commanders, including Alncak and Subutai, as well as the Selçuk assassin Beybolat, who works with the Mongols. Beybolat arrives disguised as Albast after the death of his father, Umur Bey, Bey of the Umurolu tribe, who was sent to become the new tax collector of Söüt.
Umur Bey was assassinated by Dragos, a disgraced Byzantine commander disguised as the Söüt Zangoç (transl. bellringer), who sought to take over the town. Beybolat, who succeeds his father, and Dragos, who takes control of Lefke Castle after murdering the innocent Tekfur Yannis, cause many problems for Ertugrul, including Beybolat’s temporary control of Söüt.
Beybolat’s sister, lbilge, is the only person in her family who supports justice; with her assistance, Erturul defeats and kills both Beybolat and Dragos. Following Beybolat’s death, Erturul must contend with Arikbuka, a feared Mongol spy and Alncak’s blood brother, as well as Qiyat, a spy who works for Hulagu against Berke, Erturul’s ally and the Han of the Golden Horde.
Ertugrul Season 5 concludes with Arikbuka and Qiyat’s deaths, as well as Erturul’s marriage to lbilge Hatun. Watch Previous Dirilis Ertugrul Season 4 English Subtitles.
