International Day of Conscientious Objector is observed worldwide every May 15. This day highlights individuals who refuse to participate in armed conflicts for moral, political, or religious reasons. In many countries, conscientious objectors have the option to serve in public roles as an alternative to military service, although some nations do not recognize this right and may prosecute these individuals. Various events mark the observance, including a ceremony at the Commemorative Stone in London, where the names of those who have refused to kill are read aloud, and white flowers are laid to honor them. The day serves to commemorate those who reject militarism and to remember those who have faced persecution for their beliefs.
