Of all the endeavours by the First Dáil, perhaps none was more important or successful than the work to promote the republican cause through the national and international media.
The institutional vehicle for this work was the Department of Propaganda, re-named the Ministry of Publicity during the cease-fire of 1921. The agency made a significant contribution to the survival of republicanism during the dark months of 1920-21, both by bolstering the morale of those working for that cause and by undermining the self-confidence of its opponents. This it did by dint of the labours and talent of the small staff who undertook most of its work, and in the face of severe obstacles placed in its way by British counter-measures. Key to the success were the Ministers at the apex of the machine, and the assistants through which they worked.
