Persecution of homosexuals in Nazi Germany and the Holocaust
The pink triangle, rendered in hot pink as a gay pride and gay rights symbol, was originally rendered in pink and used pointed downward on a Nazi concentration camp badge to denote homosexual men.
Upon the rise of Adolf Hitler, gay men and, to a lesser extent, lesbians, were two of the numerous groups targeted by the Nazi Party and were ultimately among Holocaust victims. Beginning in 1933, gay organizations were banned, scholarly books about homosexuality, and sexuality in general, were burned, and homosexuals within the Nazi Party itself were murdered.
The Gestapo compiled lists of homosexuals, who were compelled to sexually conform to the "German norm."
Between 1933 and 1945, an estimated 100,000 men were arrested as homosexuals, of whom some 50,000 were officially sentenced.
Most of these men served time in regular prisons, and an estimated 5,000 to 15,000 of those sentenced were incarcerated in Nazi concentration camps.
It is unclear how many of the 5,000 to 15,000 eventually perished in the camps, but leading scholar Rüdiger Lautmann believes that the death rate of homosexuals in concentration camps may have been as high as 60%.
Homosexuals in the camps were treated in an unusually cruel manner by their captors.
