Explore Southern Ireland

Southern Ireland was the larger of the two parts of Ireland that were created when Ireland was partitioned under the Government of Ireland Act 1920. It comprised 26 of the 32 counties of Ireland or about five-sixths of the area of the island, whilst the remaining six counties in the northeast of the island formed Northern Ireland.  Southern Ireland included County Donegal, despite it being the largest county in Ulster and the most northerly county in all of Ireland.
