act of union
Act of Union. Any of several acts of Parliament uniting various parts of Great Britain. • The term applies to (1) the Laws in Wales Act (1535), which united Wales with England and made that principality subject to English law, and (2) the Union with Ireland Act (1800), which abolished the Irish Parliament and incorporated Ireland into the United Kingdom of Great Britain and Ireland. It is used loosely in reference to the Union with Scotland in 1707, which was made not by statute but by treaty, approved by separate acts of the parliaments of Scotland and England, which by the treaty dissolved each parliament and created the new state of Great Britain with one parliament, the Parliament of Great Britain.
