Irish Republican Army–Soviet Union collaboration

During the Irish revolutionary period (1912-1923) and later Soviet Comintern trained Marxist operatives including Betty Sinclair and other Marxists like Michael O'Riordan would play roles in the establishment of Fronts and provocative agitation activities which led to the ignition of The Troubles (late 1960s - 1998) in which there were varying degrees of collaboration and contacts between the Soviet Union and the Irish movement.
