Anti-federalists and federalists

Anti didn't support and federalist did.

Is this it During the American Revolution and its immediate aftermath, the term federal was applied to any person who supported the colonial union and the government formed under the Articles of Confederation. After the war, the group that felt the national government under the Articles was too weak appropriated the name Federalist for themselves. Historian Jackson Turner Main wrote, "to them, the man of 'federal principles' approved of 'federal measures,' which meant those that increased the weight and authority or extended the influence of the Confederation Congress."[1]

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.[2]

The Anti-Federalists were composed of diverse elements, including those opposed to the Constitution because they thought that a stronger government threatened the sovereignty and prestige of the states, localities, or individuals; those that claimed a new centralized, disguised "monarchic" power that would only replace the cast-off despotism of Great Britain with the proposed government; and those who simply feared that the new government threatened their personal liberties. Some of the opposition believed that the central government under the Articles of Confederation was sufficient. Still others believed that while the national government under the Articles was too weak, the national government under the Constitution would be too strong. Another complaint of the Anti-Federalists was that the Constitution provided for a centralized-rather than federal-government (and in The Federalist Papers, James Madison admits that the new Constitution has the characteristics of both a centralized and federal form of the government) and that a truly federal form of government was a leaguing of states as under the Articles of Confederation.

During the period of debate over the ratification of the Constitution, numerous independent local speeches and articles were published all across the country. Initially, many of the articles in opposition were written under pseudonyms, such as "Brutus" (likely Melancton Smith[3]), "Centinel" (likely Samuel Bryan), and "Federal Farmer." Eventually, famous revolutionary figures such as Patrick Henry came out publicly against the Constitution. They argued that the strong national government proposed by the Federalists was a threat to the rights of individuals and that the President would become a king. They objected to the federal court system created by the proposed constitution. This produced a phenomenal body of political writing; the best and most influential of these articles and speeches were gathered by historians into a collection known as the Anti-Federalist Papers in allusion to the Federalist Papers.

ntentious. Finally, after long debate, a compromise (known as the "Massachusetts compromise") was reached. Massachusetts would ratify the Constitution with recommended provisions in the ratifying instrument that the Constitution be amended with a bill of rights. (The Federalists contended that a conditional ratification would be void, so the recommendation was the strongest support that the ratifying convention could give to a bill of rights short of rejecting the Constitution.
