The United States Senate is the upper chamber of the United States Congress. Together, the United States Senate and the United States House of Representatives (the lower chamber of Congress) comprise the federal bicameral legislature of the United States. The Senate plays a role in the passage of federal legislation; it also confirms presidential appointments and provides a vital check and balance on the powers of the executive and judicial branches of government.
The composition and powers of the Senate are established by Article One of the United States Constitution. Each of the 50 states is represented by two senators who serve staggered terms of six years, for a total of 100 senators. From 1789 to 1913, each senator was appointed by the state legislature of the state they represented. Since 1913, each senator is elected by a statewide popular vote, as required by the Seventeenth Amendment.
As the upper chamber of Congress, the Senate has several powers of advice and consent. These include the approval of treaties, and the confirmation of Cabinet secretaries, federal judges (including justices of the Supreme Court), flag officers, regulatory officials, ambassadors, other federal executive officials and federal uniformed officers. If no candidate receives a majority of electors for vice president, the duty falls to the Senate to elect one of the top two recipients of electors for that office. The Senate conducts trials of those impeached by the House. The Senate has typically been considered both a more deliberative and prestigious body than the House of Representatives due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere.
The Senate chamber is located in the north wing of the Capitol Building in Washington, D.C. The vice president of the United States serves as presiding officer and president of the Senate by virtue of that office, despite not being a senator, and has a vote only if the Senate is equally divided. In the vice president's absence, the president pro tempore, who is traditionally the senior member of the party holding a majority of seats, presides over the Senate. In the early 1920s, the practice of majority and minority parties electing their floor leaders began. The Senate's legislative and executive business is managed and scheduled by the Senate majority leader.
History
The drafters of the Constitution debated more about how to award representation in the Senate than about any other part of the Constitution. While bicameralism and the idea of a proportional "people's house" were widely popular, discussions about Senate representation proved contentious. In the end, some small states—unwilling to give up their equal power with larger states under the Articles of Confederation—threatened to secede and won the day by a vote of 5–4 in what became known as the Connecticut Compromise. The Connecticut Compromise provided, among other things, that each state—regardless of population—would be represented by two senators.
First convened in 1789, the Senate of the United States was formed on the example of the ancient Roman Senate. The name is derived from the , Latin for council of elders, derived from , meaning old man in Latin. Article Five of the Constitution stipulates that no constitutional amendment may be created to deprive a state of its equal suffrage in the Senate without that state's consent. The United States has had 50 states since 1959, thus the Senate has had 100 senators since 1959.
Before the adoption of the Seventeenth Amendment in 1913, senators were elected by the individual state legislatures. Problems with repeated vacant seats due to the inability of a legislature to elect senators, intrastate political struggles, bribery and intimidation gradually led to a growing movement to amend the Constitution to allow for the direct election of senators.

Qualifications
Article I, Section 3, of the Constitution, sets three qualifications for senators: (1) they must be at least 30 years old; (2) they must have been citizens of the United States for at least nine years; and (3) they must be inhabitants of the states they seek to represent at the time of their election. The age and citizenship qualifications for senators are more stringent than those for representatives. In Federalist No. 62, James Madison justified this arrangement by arguing that the "senatorial trust" called for a "greater extent of information and stability of character":
