Historical Statutes and Background on Early Irish Law

Before 1921, Statutes which applied to Ireland included UK statutes which originally applied to Ireland, or those UK statutes extended to Ireland by the Irish Parliament. For the period of 1800-1921, the Union period, statutes applying to Ireland are in the Public General Acts of the UK parliament.
