A legislature (UK: /ˈlɛdʒɪslətʃər/, US: /-ˌleɪtʃər/) is a deliberative assembly that holds the legal authority to make law and exercise political oversight within a political entity such as a state, nation, or city. Legislatures are among the principal institutions of state, typically contrasted with the executive and judicial institutions. They may exist at different levels of governance—national, subnational (state, provincial, or regional), local, or supranational—such as the European Parliament.
In most political systems, the laws enacted by legislatures are referred to as primary legislation. Legislatures may also perform oversight, budgetary, and representative functions. Members of a legislature, called legislators, may be elected, indirectly chosen, or appointed, and legislatures may be unicameral, bicameral, or multicameral, depending on their constitutional design.
