Parliament

Political Institution going back to the Middle Ages. Divided into House of Commons and House of Lords. In the 17th century Parliament opposed the monarch (see: Charles I, Civil War, Oliver Cromwell). After the Glorious Revolution in 1688 it more and more came to dominate politics.

• UK Parliament (Westminster Parliament)

Devolved national parliaments (with limited rights of legislation):

• Scottish Parliament
• National Assembly for Wales

First mention of the term in 1236, then just referring to a council of advisors to the monarch.
