Multicameralism

In contrast to unicameralism, and bicameralism, multicameralism is the condition in which a legislature is divided into more than two deliberative assemblies, which are commonly called "chambers" or "houses".^[1]^[2] This usually includes tricameralism with three chambers, but can also describe a system with any amount more. The word "multicameral" can also relate in other ways to its literal meaning of "many chambered" with use in science or biology.

The real patterns of the past are those that disappeared because they were abolished more or less recently. Most of them can be jointly defined as 'multicameralism', because they featured a number of chambers greater than two.
