The RushBagot Treaty or RushBagot Disarmament was a treaty between the United States and Great Britain limiting naval armaments on the Great Lakes and Lake Champlain, following the War of 1812. It was ratified by the United States Senate on April 16, 1818, and was confirmed by Canada, following Confederation in 1867.

The treaty provided for a large demilitarization of lakes along the international boundary, where many British naval arrangements and forts remained. The treaty stipulated that the United States and British North America could each maintain one military vessel (no more than 100 tons burden) as well as one cannon (no more than eighteen pounds) on Lake Ontario and Lake Champlain. The remaining Great Lakes permitted the United States and British North America to keep two military vessels "of like burden" on the waters armed with "like force". The treaty, and the separate Treaty of 1818, laid the basis for a demilitarized boundary between the U.S. and British North America.

The United States Senate is the upper chamber of the United States Congress, with the House of Representatives being the lower chamber. Together they compose the national bicameral legislature of the United States.

The composition and powers of the Senate are established by Article One of the United States Constitution. The Senate is composed of senators, each of whom represents a single state in its entirety. Each state is equally represented by two senators who serve staggered terms of six years. There are currently 100 senators representing the 50 states. The vice president of the United States serves as presiding officer and president of the Senate by virtue of that office, and has a vote only if the senators are 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.

As the upper chamber of Congress, the Senate has several powers of advice and consent which are unique to it. These include the approval of treaties, and the confirmation of Cabinet secretaries, federal judges (including Federal Supreme Court justices), 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 is widely considered both a more deliberative and more 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.From 1789 to 1913, senators were appointed by legislatures of the states they represented. They are now elected by popular vote following the ratification of the Seventeenth Amendment in 1913. 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.

The Senate chamber is located in the north wing of the Capitol Building in Washington, D.C.
