Federalist No. 51

James Madison, 1787 — Ways to Control the Powers of a Strong Central Government

Basic Information

Author: James Madison (Publius) · Year: 1787

Main Topic: Separation of powers and checks and balances prevent tyranny. This is a Required Source on the Argument Essay FRQ.

Memory Tricks

"51 = Check and Balance" — Federalist 51 is all about checks and balances — each branch must have the tools to resist encroachments by the others.

"Angels Quote = Human Nature" — If men were angels, no government would be necessary. Madison justifies ALL constitutional design based on human imperfection.

"Ambition Checks Ambition" — Core mechanism: give each branch its own ambitions and they naturally resist each other's power grabs.

Bullet Point Summary

A centralized government must have powers to function, but there must be ways to control those in power.

Branches must have independent powers to complete their tasks (Separation of Powers).

Branches must have clear duties that are specifically defined and limited (Limited Government).

Branches should have ways to check the powers of other branches (Checks and Balances).

Important Quotes

"If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary."

"It is evident that each department should have a will of its own; and consequently should be so constituted that the members of each should have as little agency as possible in the appointment of the members of the others."

"The remedy for this inconveniency is to divide the legislature into different branches; and to render them, by different modes of election and different principles of action, as little connected with each other as the nature of their common functions will admit."

AP-Style Argument Essay Prompt

Develop an argument that evaluates whether the system of checks and balances effectively prevents any one branch from accumulating too much power in the modern era.
