Query: What was the only state-run educational system in Ireland prior to comprehensive schools?
Context: Comprehensive schools were introduced into Ireland in 1966 by an initiative by Patrick Hillery, Minister for Education, to give a broader range of education compared to that of the vocational school system, which was then the only system of schools completely controlled by the state. Until then, education in Ireland was largely dominated by religious persuasion, particularly the voluntary secondary school system was a particular realisation of this.
