Parliament of Great Britain
The parliament came into existence because the Parliament of England and the Parliament of Scotland ratified the Treaty of Union. Both parliaments made legislation (the Acts of Union 1707) to make a new unitary state with anew legislature. These acts of parliament created a new United Kingdom of Great Britain and dissolved (or ended) the separate English and Scottish parliaments. The British parliament met in the old home of the Parliament of England, in the old Palace of Westminster, in the City of Westminster near the City of London. This parliament lasted nearly a century, until the Act of Union 1800 merged the separate Parliament of Great Britain and the Irish Parliament into a single Parliament of the United Kingdom. It became effective 1 January 1801, the same date the kingdom of Ireland joined with Great Britain to form the United Kingdom of Great Britain and Ireland.
