History of the United States Senate
The United States Senate is the upper chamber of the United States Congress, which along with the United States House of Representatives—the lower chamber—comprises the legislative branch of the federal government of the United States. Like its counterpart, the Senate was established by the United States Constitution and convened for its first meeting on March 4, 1789 at Federal Hall in New York City. The history of the institution begins prior to that date, at the 1787 Constitutional Convention, in James Madison's Virginia Plan, which proposed a bicameral national legislature, and in the controversial Connecticut Compromise, a 5–4 vote that gave  states disproportionate power in the Senate. Constitutional creation 
The U.S. Senate, named after the ancient Roman Senate, was designed as a more deliberative body than the U.S. House. Edmund Randolph called for its members to be "less than the House of Commons ... to restrain, if possible, the fury of democracy." According to James Madison, "The use of the Senate is to consist in proceeding with more coolness, with more system, and with more wisdom, than the popular branch." Instead of two-year terms as in the House, senators serve six-year terms, giving them more authority to ignore mass sentiment in favor of the country's broad interests. The smaller number of members and staggered terms also give the Senate a greater sense of community. Despite their past grievances with specific ruling British governments, many among the Founding Fathers of the United States who gathered for the Constitutional Convention had retained a great admiration for the British system of governance. Alexander Hamilton called it "the best in the world," and said he "doubted whether anything short of it would do in America." In his Defense of the Constitutions of Government of the United States, John Adams stated "the English Constitution is, in theory, both for the adjustment of the balance and the prevention of its vibrations, the most stupendous fabric of human invention." In general, they viewed the Senate to be an American version of House of Lords. John Dickinson said the Senate should "consist of the most distinguished characters, distinguished for their rank in life and their weight of property, and bearing as strong a likeness to the British House of Lords as possible." Apportionment showdown 
The apportionment scheme of the Senate was by far the most controversial debate of the Constitutional Convention. Hamilton, who was joined in opposition to equal suffrage by Madison, said equal representation despite population differences "shocks too much the ideas of justice and every human feeling." Referring to those who demanded equal representation, Madison called for the Convention "to renounce a principle which was confessedly unjust." The delegates representing a majority of Americans might have carried the day, but at the Constitutional Convention, each state had an equal vote, and any issue could be brought up again if a state desired it. The state delegations originally voted 6–5 for proportional representation, but small states without claims of western lands reopened the issue and eventually turned the tide towards the status quo from the Articles of Confederation (one state, one vote). On the final vote, the five states in favor of equal apportionment in the Senate—Connecticut, North Carolina, Maryland, New Jersey, and Delaware—only represented one-third of the nation's population. The four states that voted against it—Virginia, Pennsylvania, South Carolina, and Georgia—represented almost twice as many people than the proponents. Convention delegate James Wilson wrote "Our Constituents, had they voted as their representatives did, would have stood as 2/3 against equality, and 1/3 only in favor of it". One reason a couple large states voted for the Connecticut Compromise was a fear that the small states would either refuse to join the Union, or, as Gunning Bedford Jr. of Delaware threatened, "the small ones w[ould] find some foreign ally of more honor and good faith, who will take them by the hand and do them justice". Senate historian Daniel Wirls cites the poor writing of the main alternative, the Virginia Plan, as contributing to its failure. Gunning Bedford Jr. of Delaware later admitted that he only favored equal representation because it advanced the interests of his own state. "Can it be expected that the small states will act from pure disinterestedness? Are we to act with greater purity than the rest of mankind?" In Federalist No. 62, James Madison, the "Father of the Constitution," openly admitted that the equal suffrage in the Senate was a compromise, a "lesser evil," and not born out of any political theory. "[I]t is superfluous to try, by the standard of theory, a part of the Constitution which is allowed on all hands to be the result, not of theory, but 'of a spirit of amity, and that mutual deference and concession which the peculiarity of our political situation rendered indispensable.'" Since 1789, differences in population between states have become more pronounced. At the time of the Connecticut Compromise, the largest state, Virginia, had only twelve times the population of the smallest state, Delaware. As of 2020, the largest state, California, has a population that is seventy times greater than the population of the smallest state, Wyoming. In 1790, it would take a theoretical 30% of the population to elect a majority of the Senate, today it would take 17%. Once the issue of equal representation had been settled, the delegates addressed the size of the body: to how many senators would each state be entitled? Giving each state one senator was considered insufficient, as it would make the achievement of a quorum more difficult. A proposal from the Pennsylvania delegates for each state to elect three senators was discussed, but the resulting greater size was deemed a disadvantage. When the delegates voted on a proposal for two senators per state, all states supported this number. 1789–1865 
The Senate originally met, virtually in secret, on the second floor of Federal Hall in New York City in a room that allowed no spectators. For five years, no notes were published on Senate proceedings. A procedural issue of the early Senate was what role the vice president, the President of the Senate, should have. The first vice president was allowed to craft legislation and participate in debates, but those rights were taken away relatively quickly. John Adams seldom missed a session, but later vice presidents made Senate attendance a rarity. Although the founders intended the Senate to be the slower legislative body, in the early years of the Republic, it was the House that took its time passing legislation. Alexander Hamilton's Bank of the United States and Assumption Bill (he was then Treasury Secretary), both of which were controversial, easily passed the Senate, only to meet opposition from the House. In 1797, Thomas Jefferson began the vice presidential tradition of only attending Senate sessions on special occasions. Despite his frequent absences Jefferson did make his mark on the body with the Senate book of parliamentary procedure, his 1801 Manual of Parliamentary Practice for the Use of the Senate of the United States, which is still used. The decades before the American Civil War are thought of as the "Golden Age" of the Senate. Backed by public opinion and President Jefferson, in 1804, the House voted to impeach Supreme Court Justice Samuel Chase, 73–32. The Senate voted against conviction, 18–16. The Senate seemed to bring out the best in Aaron Burr, who as vice president presided over the impeachment trial. At the conclusion of the trial Burr said:

Even Burr's many critics conceded that he handled himself with great dignity, and the trial with fairness. Over the next few decades the Senate rose in reputation in the United States. John C. Calhoun, Daniel Webster, Thomas Hart Benton, Stephen A. Douglas, and Henry Clay overshadowed several presidents. Sir Henry Maine called the Senate "the only thoroughly successful institution which has been established since the tide of modern democracy began to run." William Ewart Gladstone said the Senate was "the most remarkable of all the inventions of modern politics. Among the greatest of debates in Senate history was the Webster–Hayne debate of January 1830, pitting the sectional interests of Daniel Webster's New England against Robert Y. Hayne's South. During the pre-Civil War decades, the debate over slavery consumed the Senate with the House consistently opposed to slavery. Since the banning of slavery north of the Mason–Dixon line a lot of effort went into maintaining equal numbers of slave and free states in order to preserve southern states' ability to preserve slavery. In the Missouri Compromise of 1820, brokered by Henry Clay, Maine was admitted to the Union as a free state to counterbalance Missouri. The Compromise of 1850, brokered by Henry Clay and Stephen Douglas, may have also helped postpone the Civil War. 1865–1913 

In the post-Civil War era, the Senate dealt with great national issues such as Reconstruction and monetary policy. Given the strong political parties of the Third Party System, the leading politicians controlled enough support in state legislatures to be elected Senators. In an age of unparalleled industrial expansion, entrepreneurs had the prestige previously reserved to victorious generals, and many were elected to the Senate. In 1890–1910 a handful of Republicans controlled the chamber, led by Nelson Aldrich (Rhode Island), Orville H. Platt (Connecticut), John Coit Spooner (Wisconsin), William Boyd Allison (Iowa), along with national party leader Mark Hanna (Ohio). Aldrich designed all the major tax and tariff laws of the early 20th century, including the Federal reserve system. Among the Democrats Arthur Pue Gorman of Maryland stood out. From 1871 to 1898, the Senate did not approve any treaties. The Senate scuttled a long series of reciprocal trade agreements, blocked deals to annex the Dominican Republic and the Danish West Indies, defeated an arbitration deal with Britain, and forced the renegotiation of the pact to build the Panama Canal. Finally, in 1898, the Senate nearly refused to ratify the treaty that ended the Spanish–American War. 1913–1945 
The Senate underwent several significant changes during the presidency of Woodrow Wilson, the most profound of which was the ratification of the 17th Amendment in 1913, which provided for election of senators by popular vote rather than appointment by the state legislatures. Another change that occurred during the presidency of Woodrow Wilson was the limitation of the filibuster through the cloture vote. The filibuster was first used in the early Republic, but was seldom seen during most of the 19th century. It was limited as a response to the filibuster of the arming of merchant ships in World War I. At that time, the public, the House, the great majority of the Senate, and the president wanted merchant ships armed, but less than 20 Senators, led by William Jennings Bryan fought to keep US ships unarmed. Wilson denounced the group as a "group of willful men". The post of Senate Majority Leader was also created during the Wilson presidency. Before this time, a Senate leader was usually a committee chairman, or a person of great eloquence, seniority, or wealth, such as Daniel Webster and Nelson Aldrich. However, despite this new, formal leadership structure, the Senate leader initially had virtually no power, other than priority of recognition from the presiding officer. Since the Democrats were fatally divided into northern liberal and southern conservative blocs, the Democratic leader had even less power than his title suggested. Rebecca Felton was sworn in as a Senator for Georgia on November 21, 1922, and served one day; she was the first woman to serve in the Senate. Joseph T. Robinson of Arkansas, the Democratic leader from 1923 to 1937, saw it as his responsibility not to lead the Democrats, but to work the Senate for the president's benefit, no matter who the president was. When Coolidge and Hoover were president, he assisted them in passing Republican legislation. Robinson helped end government operation of Muscle Shoals, helped pass the Hoover Tariff, and stymied a Senate investigation of the Power Trust. Robinson switched his own position on a drought relief program for farmers when Hoover made a proposal for a more modest measure. Alben Barkley called Robinson's cave-in "the most humiliating spectacle that could be brought about in an intelligent legislative body." When Franklin Roosevelt became president, Robinson followed the new president as loyally as he had followed Coolidge and Hoover. Robinson passed bills in the Hundred Days so quickly that Will Rogers joked "Congress doesn't pass legislation any more, they just wave at the bills as they go by. In 1932 Hattie Caraway of Arkansas became the first woman elected to the Senate. In 1937 the Senate opposed Roosevelt's "court packing" plan and successfully called for reduced deficits. Since 1945 

The most infamous Senate drama of the early 1950s was Wisconsin Senator Joseph McCarthy's investigations of alleged communists. After years of unchallenged power, McCarthy fell as a result of producing little evidence for his claims and the claims became more elaborate, even questioning the leadership of the United States Army. McCarthy was censured by the Senate in 1954. In its early history, the Senate majority leader had few formal powers. But in 1937, the rule giving majority leader right of first recognition was created. With the addition of this rule, the Senate majority leader enjoyed far greater control over the agenda of which bills to be considered on the floor. During Lyndon Baines Johnson's tenure as Senate leader, the leader gained new powers over committee assignments. In 1971 Paulette Desell was appointed by Senator Jacob K. Javits as the Senate's first female page. In 2009 Kathie Alvarez became the Senate's first female legislative clerk. See also
