After the conquest of Anatolia by Seljuk Turks, a form of traditional freestyle wrestling called "Karakucak Güreşi" (literally "Ground hug") was popularized, where special leather clothing was sanctioned and wrestlers commenced the activity by pouring olive oil on their bodies in order to make it harder for the wrestler grip one's opponent. This form continued to what is today known as Yağlı Güreş or Turkish oil wrestling. In the Ottoman Empire, wrestlers learned the art in special schools called tekke (), which were not merely athletic centres, but also spiritual centres. Wrestlers oil one another prior to matches as a demonstration of balance and mutual respect. If a man defeats an older opponent, he kisses the latter's hand (a sign of respect for elders in Turkey). Matches are held all over Turkey throughout the year, but in early summer, around 1000 competitors gather in Kırkpınar for an annual three-day wrestling tournament to determine who will be the winner or baspehlivan ("chief wrestler") of Turkey. Ottoman chroniclers and writers attest that the Kırkpınar Games have been held every year since 1362, making them the world's oldest continually sanctioned sporting competition. The games have been cancelled only about 70 times. The original site was some distant. In 1924, they were moved to the present location after the Balkan War. There are some organized oil wrestling competitions outside Turkey, particularly by the Royal Dutch Power Sport Federation ("KNKF Koninklijke Nederlandse Krachtsport en Fitnessfederatie") in the Netherlands. It is notable that all of the pehlivans listed above were born into Turkish families in Bulgaria, which was then part of the Ottoman Empire. These aghas were awarded a golden belt. A to Z kids.com
