The House of Commons of England started to evolve in the 13th and 14th centuries. It became the House of Commons of Great Britain after the political union with Scotland in 1707, and assumed the title of ’House of Commons of Great Britain and Ireland’ after the political union with Ireland at the start of the 19th century. The "United Kingdom" referred to was the United Kingdom of Great Britain and Ireland from 1800, and became the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State in 1922. Accordingly, the House of Commons assumed its current title.
