White Armband Day is marked every 31st of May to honor victims of the ethnic cleansing of Prijedor in 1992.
May 31 is commemorated as White Armband Day because, in 1992, Bosnian Serb authorities in Prijedor ordered the non-Serb population of about 65,000 to identify themselves as such by wearing white armbands around their left upper arm and marking their homes with white flags.
Nearly 50,000 were then expelled and another 5,209 were murdered. Most of these men, women, and children were incarcerated in one of the three infamous concentration camps near Prijedor – Keraterm, Omarska, and Trnopolje. The victims were then subject to various forms of torture for up to several hundred days before they were either transferred or released.
These white armbands are reminiscent of the yellow Star of David the Nazi German government ordered all Jews to wear prior to the Holocaust in 1939.
The primary goal of organizing this event was to raise awareness of White Armband Day and of what transpired in Prijedor in 1992.
