A unicameral legislature is a type of legislative body that consists of a single chamber or house, as opposed to a bicameral system which has two separate chambers. This structure can simplify the lawmaking process and make governance more efficient, but it can also limit representation and checks and balances compared to a bicameral system. The concept is particularly relevant when discussing the early governmental structures in the United States, especially in relation to the challenges faced under the Articles of Confederation and the debates during the Constitutional Convention.
