The Catholic Worker movement is an egalitarian and communitarian movement founded in 1932 centred and originating from the Catholic faith and drawing heavily from anarchist thought.  The movement is centred on communal housing — residents live simple lives dedicated to helping the poor, resisting war and fighting social injustice.  Each house is autonomous and there is no global or regional Catholic Worker headquarters — this autonomy and lack of centralized power are ideas that clearly rooted in anarchism and which would be later espoused by activist and collective spaces created after the counter-cultural revolution of the nineteen-sixties.

Income for the house can come from in-house business activities, or from residents working outside jobs.  There are currently 198 houses in the United States, 6 in Canada and 2 in Mexico.  The movement came into focus back in 2005-6 when Catholic Worker James Loney, along with three others from his Christian Peacemaker Team were kidnapped and held for ransom in Iraq.  Loney has been a long-time activist with Zacchaues House, a Catholic Worker house in Toronto, Canada.
