Parliament of Southern Ireland

The Parliament of Southern Ireland was a Home Rule legislature established by the British Government during the Irish War of Independence under the Government of Ireland Act 1920. It was designed to legislate for Southern Ireland, a political entity which was created by the British Government to solve the issue of rising Irish nationalism and the issue of partitionism, while retaining the whole of Ireland as part of the United Kingdom.
