Kuruluş: Osman season 1

The first season of the Turkish TV series, Kuruluş: Osman, created by Mehmet Bozdağ, premiered on 20 November 2019 and concluded on 24 June 2020.

Plot
10 or 15 years after the Berke-Hulagu war, Ertuğrul Ghazi goes to Konya and he leaves his brother, Dündar Bey, in charge of his tribe. Dündar Bey is easily swayed by others into doing their misdeeds. He falls into the trap of the devious Selçuk Sançak Bey, Alişar, and the merciless princess of Kulucahisar, Sofia, who seeks to kill all the Turks. Osman, Dündar's nephew, can see through Alişar and Sofia's plans and warns him about them, despite his refusal to listen. As they continue to build more tension against the Kayı, Geyhatu sends Komutan Balgay to cause more trouble and stop the Kayı, especially Osman, from rebelling against the Mongols. Dündar, who bows down to the Mongols becoming the Sançak Bey, can't see Alişar's anger over his position being given over to him and he believes him when Alişar blames Osman for his son's killing. Soon after, along with the threat from Kulucahisar, Dündar is shown the truth, Alişar is beheaded by Osman, and Osman has married his love, Bala. Following this, after many difficulties, Balgay is presumably killed by Osman while Kulucahisar is conquered by the Kayı with Sofia's death happening in the process.

Production
The season was written and produced by Mehmet Bozdağ and directed by Metin Günay. The theme music is by Alpay Göktekin and Zeynep Alasya.

Filming
It was filmed in a plateau set up in Riva, Beykoz. A separate part of the shooting location was reserved for the horses and animals of the series, where they lived in a natural environment and were looked after by their instructors. At the shooting location of the series, huge castles, inns, baths, mosques, churches were meticulously built to the finest detail. At the time when the series was first being filmed, 60 separate teams of carpenters were working on the plateau, the largest in Europe, and 1500 people were working feverishly for the first season. In the series, an 800-meter artificial lake was transformed into a huge river.

Casting
At first, when the series was named Diriliş: Osman, Aslıhan Karalar, the actress who played Burçin Hatun, was thought to play the role of Malhun Hatun, who didn't even appear in this season. The thought was established due to the fact that Malhun Hatun was Osman I's second wife according to history and that Aslıhan Karalar was the first young actress who was confirmed to join the series. However, in the series, Osman's first partner is Bala Hatun played by the Turkish actress Özge Törer. This was only revealed with the release of the series' first episode.

Music
The theme music is by Alpay Göktekin and Zeynep Alasya. Alpay Göktekin died on 5 May 2020, so therefore, could only compose the music for season one of the series.

Release
The first trailer for the season was released on 14 October 2019. The second trailer was launched on 24 October 2019 and fans were waiting for the new series to finally be aired on 20 November 2019 on ATV (Turkey).
