Irish Brigade (Spanish Civil War)

The Irish Brigade (Spanish: Brigada Irlandesa, Irish: Briogáid na hÉireann) fought on the Nationalist side of Francisco Franco during the Spanish Civil War. The unit was formed wholly of Roman Catholics by the politician Eoin O'Duffy, who had previously organised the banned quasi-fascist Blueshirts and openly fascist Greenshirts in Ireland.
