During the period between the Irish Civil War and [[World War II]], the IRA was largely engaged in social issues, which they approached from a left-wing perspective. While a number of IRA men joined the socialist and communist [[International Brigades]] in the [[Spanish Civil War]], they engaged in generally non-violent protest in Ireland. This approach was unpopular, partially due to the influence of the conservative Catholic Church in Ireland, and IRA membership dwindled. | During the period between the Irish Civil War and [[World War II]], the IRA was largely engaged in social issues, which they approached from a left-wing perspective.
