Osman Bey is the main protagonist in the Turkish TV series, Kuruluş: Osman, portrayed by Burak Özçivit. He also appears as a supporting character in its predecessor, Diriliş: Ertuğrul, where he is played by Emre Üçtepe. The character is based on Osman I, founder of the Ottoman Empire.
Background
Osman was the prophesied third son and youngest child of Ertuğrul Gazi and Halime Sultan. Before his birth, he featured in various prophetic dreams of his father, mother and grandparents, Sûleyman Sah and Hayme Hatun, suggesting he had a great destiny to be the future leader of the Turks and Muslims.
Personality
Osman was defiant as a child, eager to hold the honour of his tribe and fighting enemies, often going against his father's wishes. He formed a particularly close bond with Ertuğrul's warriors, Bamsı Beyrek and Abdurrahman Gazi, who admired his likeness with Ertuğrul.
Storyline
In Diriliş: Ertuğrul
After much foreshadowing and prophetic dreams, Osman first appears when he is born to Ertuğrul Gazi and Halime Sultan as their third son and youngest child. Unfortunately, Osman's birth was marked by tragedy as it would lead to the death of his mother, who dies giving birth to him. His mother's death would leave the newborn Osman without mother's milk. Eventually, Sügay Hatun became Osman's milk mother. He would become the target of the Mongol, Alangoya - sister of his father's enemy, Baycu Noyan. She would infiltrate the Kayı Tribe. However, he would be saved by his grandmother, Hayme. After the Kayı tribe settled in Söğüt, Osman continued to grow up and became a brave fighter, being the first of Ertuğrul's sons to master the use of weapons, despite his young age.
He then appears as a 10-year-old boy in the fifth season, which starts off with him saving an old man and his daughter from a group of Byzantines. As he is only a child, he is injured, only surviving with the help of İlbilge Hatun, daughter of Umur Bey. As the season passes onto a position where Ertuğrul decides to marry İlbilge, Osman is the only one of his sons who disagrees, showing an attachment to his mother. He again shows this attachment when he is kidnapped by the Mongols, whose shaman realises that he will found the Ottoman Empire, where he remembers his mother, and after Aybars Bey, who was kidnapped by the Byzantines, went to hug his mother after being rescued, being demonstrably upset at his own mother's absence. In the latter case, he is comforted by his paternal aunt, Selcan Hatun, whom he comes to regard as a mother figure. The season ends with Ertuğrul and İlbilge's marriage.
Season 1
Osman is shown as a courageous young man when he saves the Tekfur of Kulucahisar when he was about to be killed by the merciless Prensesi Sofia, although she later succeeds in killing the Tekfur. Osman can see through Alişar, the devious Selçuk Sançak Bey, and Sofia's plans, and warns Dündar, his uncle and the substitute Bey of the Kayı during Ertuğrul's absence, about them, despite his refusal to listen. Osman also falls in love with the daughter of Şeyh Edebali, called Bala, although the sheikh tries to teach Osman patience by initially not agreeing to the marriage. As Kulucahisar and Alişar continue to become more aggressive against the Kayı, Geyhatu sends Komutan Balgay to cause more trouble and stop the Kayı, especially Osman, from rebelling against the Mongols. Dündar causes more problems for Osman when Alişar kills Dündar's son and has it blamed on Osman. Soon after, along with the threat from Kulucahisar, Dündar is shown the truth, and Alişar is beheaded by Osman. Osman later marries Bala with Edebali's consent after seeing a symbolic dream, having had to ignore his cousin Aygül's love for him. Following this, after many difficulties, Balgay is presumably killed by Osman during the conquest of Kulucahisar with Sofia's death at the hands of Osman happening in the process.
