Welcome to 1.3! This topic focuses on the Federalists (not to be confused with Federalism or the Federalist Party) and the Anti-Federalists!
To start, the Federalists wanted the Constitution ratified. The Constitution was the proposed successor of the failed Articles of Confederation. The Constitution boasted a strong central government.
On the other hand, the Anti-Federalists opposed ratifying the Constitution. They wished for a majority of the power to be reserved to the states, just like in the Articles of Confederation.
Circling back to the Federalists, Madison’s arguments in the Federalist No. 10 are centered around controlling the mischiefs of factions in a large republic. Madison argued that in a large republic, there would be so many competing factions that no faction would be too powerful. According to Madison, this would significantly reduce the risk of tyranny of the majority, allowing the minority to keep their liberties. A faction is essentially a group of people with a common political goal, somewhat similar to political parties. Think of the pluralist democracy from 1.2.
The popular Anti-Federalist writing that adhered to popular democratic theory was Brutus No. 1, which argued for a smaller republic with less power to the national government. Brutus warned that the large, centralized government that the Federalists were proposing would get rid of personal liberties.
