Birth and "how he got his name"

Legend II (Bamsi Beyrek, Son of Bay Büre Bey or Bamsi Beyrek of the Grey Horse according to translator Geoffrey Lewis^[5]) is centered around Beyrek. In the legend, it says that once the Oghuz princes all gathered somewhere. The father of Beyrek, Bay Büre, wept when he saw everyone had a son besides him. The prince asked why he was crying, he replied that it was because he doesn't have a son to carry on his family. The princes all started to pray that Bay Büre would get a son. Bay Bichen^{[a 1]} also prayed that he would get a daughter that he would marry Bay Büre's son. And they sooner or later got the children they wanted.

Mention of Beyrek's name in the second legend of the Book of Korkut Ata

Bamsi got his name after Bay Büre sent his merchants to bring some presents. As time went by, the merchants arrived in Constantinople and bought some items, however, on their way back to Bay Büre, they were attacked by some infidels. The son of Bay Büre himself came and helped the merchants by killing all the infidels who attacked them. The son of Bay Büre didn't have any name as an Oghuz Turk was given his name when he beheaded an infidel. So the son of Bay Büre decided to receive these presents from his father instead of introducing himself. When the merchants came back to Bay Büre, they started kissing the young man's hand, the young man had already arrived and didn't tell his father about anything. The merchants then realized that the young man was the son of their great Khan, Bay Büre Khan. They also told Bay Büre about what had happened in the infidels' attack, and the young man's father found out that his son had cut off the heads of his enemies. Then the young man was given the name of Bamsi Beyrek in a gathering of the Oghuz princes.

First marriage

After he got his name, Bamsi Beyrek met with the daughter of Bay Bichen, her name was Banu Chichek. After Beyrek gave a deer to Banu's nurse, they spent some time together after which both of them learned more about each other, they even have a disagreement in which both had an arm wrestle.^[6] Bamsi Beyrek also gave her a golden ring as a sign of their engagement. When Bamsı Beyrek went back to his father, his father was already aware of his desire. And after passing a lot of resistance, including having to face Yaltajuk, Banu's evil lover who convinced everyone that Bamsi was dead, Bamsi Beyrek happily got his love, Banu Chichek, and married her.

Korkut appeared as a character in this epic, he helped Bamsi outwit Chichek's evil brother, Crazy Karchar. Karchar later repented.

Abduction and death

He was then later mentioned again in Legend XI, this epic was focused on a civil war that happened between the Outer Oghuz and the Inner Oghuz. Once every three years, Kazan Khan lets both branches of the Oghuz nobles come to his tent and take anything they wish. One year, he lets the Inner Oghuz come to his tent before the Outer Oghuz arrived. The Outer Oghuz nobles were outraged at being slighted, and they swear enmity to Prince Kazan. Beyrek was from the Inner Oghuz and his wife^{[a 2]} was from the Outer Oghuz. Uruz Koja,^{[a 3]} the Bey of the Outer Oghuz, invites Bamsi Beyrek, his son-in-law, to join the rebels to test his loyalty. Beyrek refuses to rebel against Kazan, and Uruz kills him. Kazan and the Inner Oghuz come to the Outer Oghuz to avenge Beyrek's death. In the ensuing fight, Kazan kills Uruz Koja. The Outer Oghuz nobles beg Kazan's forgiveness, which he grants, and Uruz Koja's house and lands are pillaged.

Season 1–4

Burçin Abdullah as Hafsa Hatun

The character features as a supporting character in the first two seasons, mainly fighting alongside his adoptive brothers, Doğan and Turgut, and his "Bey", Ertuğrul. In season 3, Bamsı, who at first did not want to get married and thought of his horse and swords as his family, meets a Byzantine Tekfur's daughter, Helena, who he falls in love with at first sight. Helena's father, Andros, had been killed by his adoptive son, Vasilius. Vasilius, thinking that he could manipulate Helena into marrying him, starts a feud with Bamsı together with his soldier, Teo. However, Bamsı later reveals the truth about Vasilius to Helena and marries her.^[7][8] Ertuğrul also kills Vasilius later in a fight, whilst Helena converts to Islam and takes the name 'Hafsa'.^[7][8] Bamsı is later devastated after his adoptive brother and best friend Doğan is killed by Vasilius and Ural Bey. In season 4, he becomes the Chief Alp, succeeding his adoptive brother, Turgut. He has tensions with Turgut in season 4 after disagreeing over security measures implemented by Turgut as the Çavdar Bey, which allow a pregnant Hafsa to be kidnapped by Titan, but they eventually ally together to catch the traitor in the Kayı tribe, Marya Hatun, wife of Artuk Bey. Both Turgut and Bamsı later help Ertuğrul Bey and Sungur Bey against Sadettin Köpek and Baycu Noyan.

Season 5

In the fifth season, Bamsı and Hafsa appear with two children, Aslıhan,^[7][8] who is skilled with a sword and named after Turgut's martyred wife Aslıhan Hatun, and Aybars,^[7][8] who at first loves to read and study but later, to please his father, starts using a sword more often too. Hafsa constantly attempts to convince Bamsı to leave the Kayı when she has tensions with Selcan Hatun, Ertuğrul's sister-in-law, who only has tensions with her because of stress over what had been happening to her husband and sons in Ahlat. The misunderstandings between the two escalate because of the devious Sırma of the Umuroğlu, whose brother Beybolat had been the cause of the problems faced by Selcan's family. Following a failed ambush because of Bamsı, he has his position as Chief Alp taken for a while as a punishment. Bamsı, ever caring for his wife and children, is led into a trap set by Dragos, an evil former Byzantine Commander, when attempting to save his son Aybars, kidnapped by Dragos. As the season progresses, Sırma is killed, Bamsı becomes the Chief Alp again, and Hafsa and Selcan's misunderstandings are resolved.

He also helps convert Aybars' killer, Salvador, to Islam, giving him the name 'Sıddık', and adopting him as his son. After Sıddık is martyred by Princess Sofia, Bamsı mourns for him as much as he did for Aybars. He also becomes upset upon Ertuğrul's death, with the actor, Nurettin Sönmez, saying he was left "teary-eyed".^[9] Bamsı later loyally supports Osman in becoming the Bey of the Kayı tribe, as well as protecting Ertuğrul's plans for Anatolia to hand over to Osman. He is later martyred by Kara Şaman Togay, the son of his old enemy Baycu Noyan, devastating his protege Cerkutay.
