In June 1922, just seven months after Sinn Fein negotiators signed a compromise treaty with representatives of the British government to create the Irish Free State, Ireland collapsed into civil war.

Drawing on many previously unpublished sources and newly released archival material, one of Ireland's most renowned historians lays bare the course and impact of the war and how this tragedy shaped modern Ireland.
