As an institution, the Senate emerged from the Philadelphia Convention and ratification debates without a well-defined identity. Many Federalists and Antifederalists expected the Senate to act as a council of states. Small state delegates in Philadelphia insisted on state representation in at least one chamber of the national legislature. While the Convention acceded to these delegates' wishes, it adopted several proposals, which directly weakened the Senate's role as a council of states. Long terms without the possibility of recall, per capita voting, and salaries paid from the national treasury all undermined the idea of senators as their states' ambassadors. The ratification debates only further confused the issue of the Senate's character and its relationship to the states.
State legislatures were never shy about expressing their opinions either
as recommendations or instructions. All states sent resolutions and remonstrances
to the Senate, and on important subjects they sent instructions. For the
most part, senators and state legislatures peacefully co-existed. In the
most significant episode, the Virginia legislature censured Senators William
Branch Giles and Richard Brent -one for disavowing the obligation to obey
instructions and the other for outright disobedience of its command to
oppose the rechartering of the First Bank of the United States (BUS) in
1811. This episode engendered an extensive debate in the Senate and the
states about instructions, the Senate, and the Senate's relationship with
the states and the union.
