This article is based on the premise that the social and political foundations of the geopolitical entity known as the Irish Free State was of a conservative nature, unique in Western Europe. Of course, conservative forces also featured prominently in the early twentieth-century in other European countries. However, they were counterbalanced by forces of opposition sufficiently powerful to generate a social and political balance that was practically nonexistent within the Irish Free State. When exploring the root cause of Ireland's conservative politics, I identify an ideological connection between the lack of radical forces in the Irish Free State and the revolution through which it was established. In other words, the 1916-23 Irish Revolution indisputably laid the foundations of the ideas that were to become the dominant ideology in southern Ireland during the 1920s and 1930s.
