The Yörüks, also Yuruks or Yorouks (Turkish: Yörükler; Greek: Γιουρούκοι, Youroúkoi; Bulgarian: юруци; Macedonian: Јуруци, Juruci), are a Turkish ethnic subgroup of Oghuz descent, some of whom are nomadic, primarily inhabiting the mountains of Anatolia, and partly in the Balkan peninsula. On the Balkans Yörüks are distributed over a wide area from southern Serbia, parts of Bulgaria, north to Larissa in Thessaly and southern Thrace. Their name derives from the Turkish verb yürü- (yürümek in infinitive), which means "to walk", with the word yörük or yürük designating "those who walk on the hindlegs, walkers". The Yörüks were under the Yörük Sanjak, (Turkish: Yörük Sancağı) which was not a territorial unit like the other sanjaks, but a separate organisational unit of the Ottoman Empire.
