A war resister is a person who resists war. The term can mean several things: resisting participation in all war, or a specific war, either before or after enlisting in, being inducted into, or being conscripted into a military force.
Early usage of the term "war resister" is found in the name of the War Resisters League which was formed in 1923 by men and women who had opposed World War I. The War Resisters League is a section of the London-based War Resisters' International which was originally founded in Bilthoven, Netherlands in 1921 under the name "Paco".
In 1975, the Committee on South African War Resistance, an organisation of exiled conscientious objectors, pacifists, anti-militarists and deserters from the South African Defence Force (SADF), was formed in the aftermath of South Africa’s invasion of Angola and the Soweto uprising the following year. Its aim was to raise international awareness about the role of the SADF and to provide support to objectors in exile.
In 2008 and 2009, the Parliament of Canada officially adopted the term "war resister" to include those who are not necessarily opposed to all war, but who selectively refused to participate in the Iraq War. This practice was also adopted by various media in Canada at various times.
On January 24, 2010, the term "War Resisters" was the name of a nine-minute documentary on Global Television Network television program 16:9 (TV series). Carolyn Jarvis interviewed war resisters Robin Long and Rodney Watson, and Canadian Member of Parliament Gerard Kennedy on his Bill C-440 regarding Iraq war resisters in Canada.
