House of Commons of the United Kingdom different from House of Commons of Great Britain
The House of Commons is the lower house of the Parliament of the United Kingdom. Like the upper house, the House of Lords, it meets in the Palace of Westminster in London, England. The House of Commons is an elected body consisting of 650 members known as members of Parliament (MPs). MPs are elected to represent constituencies by the first-past-the-post system and hold their seats until Parliament is dissolved.
The House of Commons of England began to evolve in the 13th and 14th centuries. In 1707 it became the House of Commons of Great Britain after the political union with Scotland, and from 1800 it also became the House of Commons for Ireland after the political union of Great Britain and Ireland. In 1922, the body became the House of Commons of the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State. Under the Parliament Acts 1911 and 1949, the Lords' power to reject legislation was reduced to a delaying power. The government is solely responsible to the House of Commons and the prime minister stays in office only as long as they retain the confidence of a majority of the Commons.History
The British parliament of today largely descends, in practice, from the Parliament of England, although the 1706 Treaty of Union, and the Acts of Union that ratified the Treaty, created a new Parliament of Great Britain to replace the Parliament of England and the Parliament of Scotland, with the addition of 45 MPs and sixteen Peers to represent Scotland. Later still the Acts of Union 1800 brought about the abolition of the Parliament of Ireland and enlarged the Commons at Westminster with 100 Irish members, creating the Parliament of the United Kingdom of Great Britain and Ireland.
The Middle English word common or commune, which is derived from the Anglo-Norman commune, meant "of general, public, or non-private nature" as an adjective and, as a substantive, "the common body of the people of any place; the community or commonalty" in the singular; "the common people, the commonalty; the lower order, as distinguished from those of noble or knight or gentle rank", or "the burgers of a town; the body of free citizens, bearing common burdens, and exercising common rights; (hence) the third estate in the English constitution; the body of people, not ennobled, and represented by the Lower House of Parliament" in the plural. The word has survived to this day in the original Anglo-Norman phrase soit baillé aux communes, with which a bill is transmitted from the House of Lords to the House of Commons.The historian Albert Pollard held a somewhat different view on the word's origins in 1920. He agreed that commons could be derived from Anglo-Norman communes, but that it referred to "civil associations" or "the counties". However, the Oxford English Dictionary, the historical dictionary of the English language, can only attest to the word meaning advocated by Pollard from the 19th and 20th centuries onwards, whereas sources for the meaning given in the previous section date from the late Middle Ages, i.e. the time of the establishment of the House of Commons.
