The Bayat tribe (Azerbaijani: Bayat tayfası, Turkish: Bayat boyu, Turkmen: Baýat taýpasy) is one of the Oghuz tribes in Turkmenistan, Iran, Turkey, Azerbaijan, Iraq, and Syria. When Oghuz Turks started to migrate from the Aral steppes to Khorasan in the 11th and 13th centuries, Bayat people spread throughout the region. They are sub-ethnic groups of Turkmens, Turkish and Azerbaijanis. Bayats are Muslim and speak a southern dialect of Azerbaijani language in Azerbaijan and Iran, or their own dialect of Turkish in Turkey.
