The Irish Civil War broke out on this day 100 years ago

The Irish civil war broke out 100 years ago with the eruption of violence in central Dublin. A split among republicans over the Anglo-Irish Treaty, signed with the London government six months earlier, led to fighting within Ireland. On 28th June 1922 the dispute came to a head at Dublin's judicial headquarters, known as the Four Courts. Historian Niamh Hassett joined Fran on the show.
