In governmental systems like that of the United States, the powers of government are divided up among different branches of government. One of these branches is the legislative branch. The United States government has a legislative branch (Congress) and each state government has its own legislative branch. The basic job of the legislative branch is to make laws, though legislative branches do typically have some other duties.
The major role of the legislative branch is to make laws for their jurisdiction. The state legislatures make laws that apply in their own state and the Congress makes laws that apply to the nation as a whole. The legislative branch, in general, writes proposed laws, studies the proposals, edits and amends them, and votes on them. The bills that they pass must be signed in to law by the chief executive, but it is the legislature that is in charge of actually creating the laws.
Legislatures have other duties. One duty is to oversee the executive branch of government. The legislature can, for example, hold hearings to look into the conduct of various government agencies. It has (at the federal level) the right to approve or reject the president’s choices for leadership roles in the government agencies. This is a major role of the legislature, but is not as important as the duty of making laws.
Congress has a few other roles that do not often come into play. For example, Congress is the body that can declare war on another country. Congress is the body that impeaches officials and tries them when they are impeached. The Senate has to ratify treaties and approve of judicial appointments for them to be valid.
Thus, the legislative branch of government has a number of roles, the most important of which is the making of laws.
Another significant aspect of the legislative branch (perhaps not in the fact that it does but that it is) is that it is the most direct aspect of representation of the people in the government. Although the President is also decided through ballots, it is the ballots of the Electoral College and is therefore a less direct representation of the people, especially because the President serves as a representative of the country rather than a smaller part, as the representatives in the Senate and the House do.
The Legislative branch makes and creates laws.
Well in short, this branch consists of the Senate and House of Representatives (Congress). There are 50 states, and there are 100 senators, which means from each state there is a total of 2 senators in the House. The Legislative branch makes laws, writes laws, and creates laws.
