[11] There are certain historical sources that state that the Anushteginids, who ruled vast parts of Central Asia from 1077 to 1231 under the title of Khwarazmshahs, descended from the Begdili tribe of the Oghuz Turks.

[12] The dynasty was founded by commander Anush Tigin Gharchai, a former Turkic slave of the Seljuq sultans, who was appointed as governor of Khwarezm.

[14] The Aq Qoyunlu Sultans claimed descent from Bayindir Khan, through a grandson of Oghuz Khagan.

[15] Ottoman historian and ambassador to the Qara Qoyunlu, Şükrullah states that Ertuğrul's lineage goes to Gökalp, a son of Oghuz Khagan.

The author states that the information was shown during a court of Jahan Shah, from a book written in Mongolian script.

When they had consulted each other and understood the custom of Oghuz (Khan), they appointed Osman khan.Bayezid I advanced this claim against Timur, who denigrated the Ottoman lineage.

But his Chinese stepmother and half-brother, who was the heir to the throne, became intimidated by his power and convinced Qara Khan that Oghuz was planning to dethrone him.

He married her as well and had three more sons whom he named Gök (Sky), Dağ (Mountain), and Deniz (Sea) (in Turkmen).

After his sons were born, Oghuz Khan gave a great toy (feast) and invited all of his begs (lords).

At the feast, he gave this order to his lords: I have become your Khan; Let's all take swords and shields; Kut (divine power) will be our sign; Gray wolf will be our uran (battle cry); Our iron lances will be a forest; Khulan will walk on the hunting ground; More seas and more rivers; Sun is our flag and sky is our tent.

One night, a large male wolf with grey fur (which is an avatar of Tengri) came to his tent in an aura of light.

Then, Oghuz and his six sons carried out campaigns in Turkistan, India, Iran, Egypt, Iraq and Syria, with the grey wolf as their guide.

Oghuz Khan broke the golden bow into three pieces and gave each to his three older sons Gün, Ay, and Yıldız.

According to Abulgazi, Oguz Khan could have lived four thousand years before Prophet Muhammad during the time of the legendary ancient king Keyumars.

[23][24] The French Encyclopedia of Diderot and d'Alembert mentions that Oghuz Khan lived long before the Persian king Cyrus II.

Stralenberg also notes that among the Central Asian peoples, Oghuz Khan enjoys the same fame as Alexander the Great and Julius Caesar among Europeans.
