The Ottoman Turks were a tribe of Central Asian Türks who come from the area that is now Uzbekistan and Turkmenistan. They crossed into Anatolia as warriors on horseback and delivered sound victories over the Byzantine Empire and the Seljuk Turks (another tribe in Anatolia with similar provenance).
