In 1920 a momentous decision was finalised - three Ulster counties, Cavan, Donegal and Monaghan would not be included in the new Northern Ireland. It was felt that the new entity would be more secure without those counties which had nationalist majorities. But they also had large, Protestant, Unionist, Loyalist minorities - then abandoned in the new Irish Free State.  

Ed Burke has written a new book – it's called ‘Ulster's Lost Counties: Loyalism and Paramilitarism since 1920’. In it he examines armed loyalism and resistance to Irish nationalism coming from the people of the three counties.
