assembly, deliberative council, usually legislative or juridical in purpose and power. The name has been given to various ancient and modern bodies, both political and ecclesiastical. It has been applied to relatively permanent bodies meeting periodically, such as the ancient Greek and Roman assemblies, the Germanic tribal assemblies, the French National Assembly, the legislative houses called assemblies in certain states of the United States, and the UN General Assembly. It has also been applied to groups sitting only for special purposes and for limited periods, such as the Westminster Assembly, which met in 1643 to draft a new constitution for the Church of England.
