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.

Osman was defiant as a child, eager to hold the honour of his tribe and fighting enemies, often going against his father's wishes.

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.

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.

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.

Osman later marries Bala with Edebali's consent after seeing a symbolic dream, having had to ignore his cousin Aygül's love for him.

Followed by Ertuğrul's return to the tribe, Yavlak Arslan, the new Uç Bey, seeks to create his own state and sees Osman as an obstacle, although they later unite against the new threat created by the Mongol Geyhatu, who allies with the new Tekfur of İnegöl, Aya Nikola, against the Turks of Anatolia.

He is eventually advised by Şeyh Edebali to marry Malhun Hatun to provide an heir to his Beylik,[2][3] which he reluctantly agrees .

He and his first wife Bala's prayers for a child were heard and soon they had a baby boy, who was named Alaeddin Ali.

However, Osman foils the Byzantine's plans by rescuing his sons, with the help of his wives, and ultimately ends up conquering Bilicek - killing its Tekfur in the process.

But Osman's elder brother Gunduz died of his injuries sustained during the battle, leaving everyone mourning his loss.

In 2020, Pakistan's Federal Minister for Science and Technology Fawad Chaudhry, met Burak Özçivit when he visited the Kuruluş: Osman set with his family.

[4][5] It is unknown when he met the Turkish actor but it's likely that it was after Osman became the Kayı Bey due to Burak's outfit.
