Parliament of Southern Ireland

The Parliament of Southern Ireland was set up during the Anglo-Irish War under the Government of Ireland Act, 1920, evolving out of the Home Rule Act 1914, to legislate for "Southern Ireland", a political entity envisaged by the British government which never became a reality. A Parliament of Northern Ireland was set up simultaneously to legislate for Northern Ireland. The Parliament of Southern Ireland consisted of two houses:

• House of Commons of Southern Ireland
• Senate of Southern Ireland

The parliament sat only once, to ratify the Anglo-Irish Treaty in order to satisfy a British demand. In reality, Dáil Éireann (which the British did not recognise), whose membership was almost identical to that of the parliament, was the only assembly with moral (if not strictly legal) authority. The parliament was abolished by the Irish Free State constitution of 1922.
