Legislature
Types of Legislatures
Two common types of legislature are those in which the executive and the legislative branches are clearly separated, as in the U.S. Congress, and those in which members of the executive branch are chosen from the legislative membership, as in the British Parliament. Respectively termed presidential and parliamentary systems, there are innumerable variations of the two forms. It should be noted that while popular assemblies of citizens, as in direct democracy, are often called legislatures, the term should properly be applied only to those assemblies that perform a representative function.
In its early history, the English
The Congress of the United States is bicameral, but rather than being rooted in societal class differences, it is based upon principles of federalism. The founders of the American republic, in order to assure acceptance of the Constitution, gave each state equal representation in the Senate, as a gesture to the smaller states, and made membership in the House of Representatives dependent upon population size, thereby favoring the larger states. Most of the American state legislatures are also bicameral.
History
While rules of law have always been a concern for society, the use of legislatures for their establishment is a relatively modern phenomenon. In earlier times, human laws were considered part of the universal natural law, discoverable through the use of reason rather than made by the declaration of the people. With the growth of belief in positive law, the increasing need in emerging modern society for adaptable law, and the decline of monarchial power, however, legislatures with law-making powers came about. One of the oldest legislatures (with the possible exception of Iceland's Althing and the Isle of Man's Tynwald) is the English Parliament, which, although originally nonelective and advisory to the king, has evolved over the centuries to the point where its lower house is now elected through universal suffrage and possesses the sovereign power of the state.
Some other modern national legislatures are the U.S.
