Origin of The Azeris - Oghuz Arrival

Oghuz Arrival

Ibn al-Athir, an Arab historian, declared that the Oghuz Turks had come to Transoxiana in the period of the caliph Al-Mahdi in the years between 775 and 785. In the period of the Abbasid caliph Al-Ma'mun (813 – 833), the name Oghuz starts to appear in the works of Islamic writers. By 780, the eastern parts of the Syr Darya were ruled by the Karluk Turks and the western region (Oghuz steppe) was ruled by the Oghuz Turks.

Oghuz dominance in Southwestern Asia begins in the 11th century, with the Seljuk Empire. The Southwestern Turkic dialects gradually supplanted the Tat, Azari, and Middle Persian dialects in northern Iran, and a variety of Caucasian languages in the Caucasus, particularly Udi, and had become the dominant during the High to Late Medieval period, under the rule of the White Sheep Turkomans and Black Sheep Turkomans (14th to 15th century), the process of Turkification being mostly complete by the Safavid period (16th century).
