A parliament is a type of legislature.
The most famous parliament is probably the Parliament of the United Kingdom, which is sometimes called the "Mother of all Parliaments".[1] The word "parliament" comes from the French word parler, which means a talk.
The Althing, the national parliament of Iceland, was founded earlier (930 AD), so it is the oldest legislature in the world still existing. However, the Althing did not function as a legislature for four centuries, and its role as a primary legislature is modern.[2][3]
