The Dublin Housing Action Committee (DHAC) was a 1960s protest group formed in response to housing shortages in Dublin, Ireland's capital city. It quickly moved to direct action and successfully squatted buildings to oppose redevelopment plans.

The British and Irish Communist Organisation (B&ICO) was a small group based in London, Belfast, Cork, and Dublin. Its leader was Brendan Clifford. The group produced a number of pamphlets and regular publications, including The Irish Communist and Workers Weekly in Belfast. Τhe group currently expresses itself through Athol Books with its premier publication being the Irish Political Review. The group also continues to publish Church & State, Irish Foreign Affairs, Labour Affairs and Problems.
