The pink triangle has become one of the symbols of the modern gay rights movement, but it originated in Nazi concentration camps during World War II. In many camps, prisoners wore badges. These badges were colored based upon the reason for imprisonment. In one common system, men convicted for sexual deviance, including homosexuality wore a pink triangle. The icon has been reclaimed by many in the post-Stonewall gay rights movement as a symbol of empowerment, and, by some, a symbol of rememberance to the suffering of others during a tragic time in history.
