Oil wrestling is one of Turkey’s most traditional sports with roots that go all the way back to ancient Mesopotamia. During the famous Kırkpınar oil-wrestling tournament in Edirne, which has been held annually since 1362, the wrestlers douse themselves in oil and then wrestle until a loser is declared (when the navel faces the sky). Oil wrestling matches can go on for up to 40 minutes and for all the peculiar oiliness, can actually be quite captivating.
