In 2011 Jim Naughten spent 4 months photographing the Herero tribe of Namibia. His book, Conflict and Costume, is an in-depth look at the bold and gorgeous costumes that have come to represent the cultural identity of the Herero people.

The style of dress was introduced during the German/Herero conflict in the early 20th century, when nearly 80% of the Herero population was wiped out. Though the attire was originally forced upon the Herero people, it has since become a tradition and point of pride. “If a warrior killed a German soldier he would take and wear their uniform as a badge of honor, and to ‘take’ or appropriate their power. A version of these uniforms is worn by Herero men today at festivals and ceremonies, to honor the fallen ancestors and to keep the memories alive.”
