“The event, in September 2012, was called ’Wrestling for Peace and Unity,’ and featured matches by two rival tribal groups, the Bor-Dinka and the Mundari. This was the first of a series of events planned in South Sudan with a focus on using the sport of wrestling to build relations between communities. Wrestling is popular among most tribal groups in South Sudan, and these matches have a long history as a customary method of resolving conflict. The goal is to use this sport to provide a space in which to build peace. It’s also a good business opportunity, considering how popular wrestling is.“
