Oil wrestling (Turkish: yağlı güreş), also called grease wrestling, is the Turkish national sport. It is so called because the wrestlers douse themselves with olive oil. The term “güreş” is shared with other forms of wrestling practiced by Turkic-speakers across Europe and Central Asia, such as the Uzbek kurash, Tuvan khuresh and Tatar köräş. The wrestlers, known as pehlivan (Persian: پهلوان meaning “hero” or “champion”) wear a type of hand-stitched lederhosen called a kisbet (sometimes kispet), which is traditionally made of water buffalo hide, and most recently has been made of calfskin.
