The Acts of Union were two Acts of Parliament: the Union with Scotland Act 1706 passed by the Parliament of England, and the Union with England Act passed in 1707 by the Parliament of Scotland. They put into effect the terms of the Treaty of Union that had been agreed on 22 July 1706, following negotiation between commissioners representing the parliaments of the two countries. The Acts joined the Kingdom of England and the Kingdom of Scotland (previously separate states with separate legislatures, but with the same monarch) into a single, united kingdom named "Great Britain".
