Irish Free State Constitution

The Constitution of the Irish Free State (Irish: Bunreacht Shaorstáit Eireann) was the second constitution of the independent Irish state.

The Constitution established a parliamentary system of government under a form of constitutional monarchy, and contained guarantees of certain fundamental rights. It was intended that the constitution would be a rigid document that, after an initial period, could be amended only by referendum.
