Circassian Anzaur Alyal poses for a portrait in the village of Tkhagapsh in the Lazerevskoye district of Sochi October 20, 2013. Tkhagapsh is one of the few remaining settlements in the Sochi region, that mainly consists of ethnic Circassians. "Some say, during the opening ceremony of the Olympics there will be Circassians in their traditional dresses walking in the first row. No one knows, its all a big secret. This would of course be a very good thing. At the same time, I would like people to understand that Circassians are more than just folklore dance and costumes. Our culture is very rich and ancient. There is much more to it," Alyal said. The writing on Alyal's cap reads "Circassian". Circassians are a people indigenous to the North Caucasus region, most of whom were scattered across the globe by a 19th century tsarist military campaign that caused the deaths of huge numbers. Many Circassians have called for the killings to be recognised as genocide, and have campaigned against the Sochi 2014 Winter Olympics, set to take place in the very same broad valleys and mountain slopes they say hold the bones of their ancestors.
