what is the main focus of federalist 51
Federalist No. 51 Federalist No. 51, titled: "The Structure of the Government Must Furnish the Proper Checks and Balances Between the Different Departments", is an essay by James Madison, the fifty-first of The Federalist Papers. This document was published on February 8, 1788, under the pseudonym Publius, the name under which all The Federalist papers were published. Federalist No. 51 addresses means by which appropriate checks and balances can be created in government and also advocates a separation of powers within the national government. This idea of checks and balances became a crucial document in the establishment of the modern U.S. system of checks and balances. One of its most important ideas, an explanation of check and balances, is the often quoted phrase, "Ambition must be made to counteract ambition."
Anti-Federalism As the Federalists moved to amend the Articles, eventually leading to the Constitutional Convention, they applied the term anti-federalist to their opposition. The term implied, correctly or not, both opposition to Congress and unpatriotic motives. The Anti-Federalists rejected the term, arguing that they were the true Federalists. In both their correspondence and their local groups they tried to capture the term. For example, an unknown anti-federalist signed his public correspondence as "A Federal Farmer" and the New York committee opposing the Constitution was called the "Federal Republican Committee." However the Federalists carried the day and the name Anti-Federalist forever stuck.[1]
