Created in 1787, the United States Senate is one of the two chambers of the Congress of the United States, the other being the House of Representatives. In the Senate, each state is equally represented by two members, regardless of population; as a result, the total membership of the body is 100. Senators serve for six-year terms that are staggered so elections are held for approximately one-third of the seats (a "class") every second year. The Vice President of the United States is the presiding officer of the Senate but is not a senator and does not vote except to break ties. The Senate is regarded as a more deliberative body than the House of Representatives; the Senate is smaller and its members serve longer terms, allowing for a more collegial and less partisan atmosphere that is somewhat more insulated from public opinion than the House. The Senate has several exclusive powers enumerated in the Constitution not granted to the House; most significantly, the President must ratify treaties and make important appointments "with the Advice and Consent of the Senate" (Article I). This fully-indexed chronology and institutional bibliography traces the sometimes tumultuous history of this august body.

The invention of the United States Senate was the most complicated and confounding achievement of the Constitutional Convention. Although much has been written on various aspects of Senate history, this is the first book to examine and link the three central components of the Senate's creation: the theoretical models and institutional precedents leading up to the Constitutional Convention; the work of the Constitutional Convention on both the composition and powers of the Senate; and the initial institutionalization of the Senate from ratification through the early years of Congress. The authors show how theoretical principles of a properly constructed Senate interacted with political interests and power politics in the multidimensional struggle to construct the Senate, before, during, and after the convention.
