Founded in October 2002, the UFPJ, short for United for Peace and Justice coalition regroups over 1300 organizations based in the United States as well as worldwide organizations, that opposed war and the policies of governments aiming toward warfare and empire building.
The coalition was created in response to the United States’ plans to invade Iraq in 2003. It was initially only meant to be a meeting of a dozens of antiwar organizations including Veterans for Peace, Peace Action, Black Voices for Peace, the American Friends Service Committee, the National Organization for Women, Not In Our Name, the National Council of Churches, and September Eleventh Families for Peaceful Tomorrows. The United for Peace and Justice coalition’s first action was a series of anti-war manifestations started on the 10th of December 2002 on the International Human Rights Day. The direct precursor of United for Peace and Justice was started by several groups such as the Green Party of the United States to and Global Exchange. The coalition was called "United We March!", and protested against the invasion of Afghanistan by the United States on the 20th April 2002.
The anti-war coalition United for Peace and Justice , which includes 1.300 associations, sent a delegate to the first international conference to support the IFC in Tokyo in January 2006, and the War Resisters League who is a member of their gropu. The UFPJ had invited a representative of the IFC, Amjad al-Jawhary, in Washington in September 2005. There is an American chapter of the UFPJ, led mainly by militants of the Communist League, a small far-left organization that struggles for freedom in Iraq, created in support of the IFC.
