George Rodger's Village of the Nubas

In 1949, the Englishman George Rodger (one of the founding members of the Magnum photo agency) learned of the existence of the Nuba tribe while travelling in the Kordofan region of the Sudan. The Nubas were a people living just as their past ancestors had lived many centuries before.
 
Remarkably, he was granted permission by the Sudanese government at the time to not only to spend time with the tribe, but to be the first ever Westerner to photograph its present-day rituals and way of life.
