The Uzbeks (Oʻzbek/Ўзбек, pl. Oʻzbeklar/Ўзбеклар) are the largest Turkic ethnic group in Central Asia. They comprise the majority population of Uzbekistan but are also found as a minority group in Afghanistan, Tajikistan, Kyrgyzstan, Kazakhstan, Turkmenistan, Russia and China. Uzbek diaspora communities also exist in Turkey, Saudi Arabia, and Pakistan.
The origin of the word Uzbek remains disputed. One view holds that it is eponymously named after Oghuz Khagan. Oghuz Khagan also known as Oghuz Beg, the word Uzbek is derived from the name of Oghuz Beg. Another states that the name means independent or the lord itself, from Oʻz (self) and the Turkic title Bek/Bey/Beg. There is another theory which holds that the pronunciation of Uz comes from one of the Oghuz Turks variously known as Uz or Uguz united with the word Bey or Bek to form uguz-bey, meaning "leader of an oguz".
