The House of Commons of England was the lower house of the Parliament of England (which incorporated Wales) from its development in the 14th century to the union of England and Scotland in 1707, when it was replaced by the House of Commons of Great Britain after the 1707 Act of Union was passed in both the English and Scottish parliaments at the time. In 1801, with the union of Great Britain and Ireland, that house was in turn replaced by the House of Commons of the United Kingdom.
