“Along with the American Declaration of Independence and the Constitution
“The most authoritative document in American history”

The Federalist Papers is a collection of articles anonymously contributed to newspapers by Alexander Hamilton, James Madison, and John Jay, who attended the Philadelphia Constitutional Convention and led the drafting of the Constitution, and who served as President of the Continental Congress, in order to explain the new Constitution to the citizens of New York, who were most opposed to its ratification, and to refute the opponents' far-fetched arguments.
At the time of publication, the pen name Publius was used.

Each of these essays clearly explains the philosophy and motivation behind the government structure proposed in the Constitution and refutes the irrationality of the arguments put forward by opponents of the Constitution (anti-federalists).
The U.S. Supreme Court still cites this text when interpreting the Constitution because it explains the Constitution through persuasive sentences and rigorous logical structure.

The Federalist Papers were published at a crucial moment in American history and provide readers with a useful intellectual guide to the crucial issues that democracy must address.

Under a vibrant central government, we could use the power and resources we receive from nature for the common good, thereby thwarting any concerted action by European nations to impede our growth.
A single central government under a new constitution would discourage joint action among European nations, removing even the incentive for their unity.
Brisk trade, expansion of maritime traffic, and a thriving shipping industry will naturally arise from America's spiritual and material needs.
Moreover, under a strong central government, we can resist the schemes of petty politicians who seek to defy or alter the inevitable and unchangeable natural order.

--- p.96, from 「No.11 Alexander Hamilton」

The doctrine of the opponents is that, as if the power of the federal government proposed by the new Constitution were too strong or too rigid, they deliberately lead us to weaken or soften it by resorting to expedients already condemned or prohibited in other cases.
If the various principles they advocate on various points were to become so widely accepted as to become general creeds, it could be said with certainty that they would render the citizens of this country utterly unfit for any kind of government.
However, there is no need to worry about this type of risk.
Because American citizens are sufficiently discerning to be persuaded into anarchy.
If our experience has not instilled in the public mind a profound and serious conviction that a more vigorous government is essential to the welfare and prosperity of society, I am seriously mistaken.

26 From Alexander Hamilton

On the one hand, the spirit of republican liberty requires that all powers emanate from the people, and that those entrusted with that power be limited to short terms, thus ensuring their constant dependence on the people. Madison explains why he set the term of office for the House of Representatives at two years.

Moreover, even for this short period, the delegation of power must be placed in the hands of the many, not the few.
On the other hand, from the perspective of the stability of the political system, those entrusted with power must maintain their positions for a considerable period of time without frequent change. This explains why, in contrast to the short two-year term of office of the House of Representatives, the term of office of the Senate is set at six years, and furthermore, only one-third of the seats in the Senate are subject to election every two years, to ensure government stability and continuity of state affairs.
Frequent elections will lead to frequent changes in representatives, and frequent changes in representatives will lead to frequent changes in the system.
However, from the perspective of the vitality of the political system, power must not only last for a certain period of time, but also be exercised by a single person. Here, Madison is alluding to the President, the head of the executive branch envisioned by the new Constitution.
The president, the head of the executive branch proposed by the new constitution, is a unique product of American politics.
The Constitutional Convention also proposed appointing two leaders of the executive branch, each responsible for a different area of ​​work, or a committee composed of several members.
However, in the end, the final decision was made to have a single person as the head of the executive branch and to call him the President.
See footnote 5 of paper 4) and footnote 7 of paper 16).

The federal government's ambitious encroachment on the powers of the states will not merely excite opposition from one or several states, but will serve as a general warning signal, uniting all the states in common purpose.
Communication networks will be opened and cooperation for resistance will be achieved.
A unified spirit will inspire and direct the whole.
In short, just as the Confederacy was formed out of fear of foreign enslavement, so the states will eventually resort to force if the federal government does not voluntarily abandon its ambitious plans.
But what level of madness could drive the federal government to such extremes? During the war with Britain, parts of our American empire encroached upon other parts.
The numerically larger side was infringing on the rights of the smaller side. Immediately after the war with Britain began, the 13 American colonies were divided between the northern and central states, which wanted independence from Britain, and the southern states, which wanted to remain colonies as long as their colonial rights were guaranteed.
However, in drafting and adopting the Declaration of Independence at the Second Continental Congress in 1776, the majority of northern and central states ignored the opinions of the southern states that opposed independence and pushed ahead with the adoption of the Declaration of Independence.
It was unfair and unwise, but not entirely unthinkable.
But what would the fight be like in the scenario we're assuming, and who would be involved? Perhaps a small group of national representatives would be fighting against the people themselves.
Or the representatives of the Federal Congress will face off against the representatives of the thirteen state legislatures, and the people of both will side with the latter.

--- p.371~372, from 「No.46 James Madison」

If the majority unites for their common interest, the rights of the minority are endangered.
However, there are only two ways to prevent this harm.
One is the power that does not depend on the majority, that is, is not subject to the constraints of society itself. In the original text, it is 'a will', and Madison uses this word to mean 'agency' or 'agencies', which are the power, force, or means to ensure the safety of the minority.
For example, it refers to laws, institutions, or binding powers that have absolute power.
Madison argues that in a republic, the use of this kind of power or means should be as restrained as possible.
See this paper, footnote 4).
One is to create a society of very different kinds of citizens, and the other is to make it difficult, if not impossible, for many unjust combinations to occur.

--- p.404~405, from 「No.51 James Madison」

The President of the United States is a public official elected by the people for a four-year term, but the British monarch is a hereditary monarch for life.
The President may be personally punished and disgraced, but the British monarch is sacred and inviolable.
The President has limited veto power over bills passed by the legislature, but the British monarch has absolute veto power.
The President has command of the Army and Navy of the United States, but the British monarch has, in addition to these powers, the power to declare war and to raise and control fleets and armies on her own authority.
Also, the former, the President, shares the power to conclude treaties with the House of Lords, a legislative body, while the latter, the British monarch, is the sole holder of the power to conclude treaties.
The former also has joint authority over the appointment of managers, but the latter has all appointment authority alone.
The former cannot grant any privileges, but the latter can grant citizenship to foreigners, make commoners nobles, and establish corporations with all the rights incidental to corporate bodies.
The President shall make no rules respecting the commerce or currency of the United States; but the Crown is in various respects the regulator of commerce, and in that capacity may open markets, large and small, for commerce, regulate weights and measures, impose embargoes for specified periods, coin money, and permit or prohibit the circulation of foreign coins.
Although the President has no jurisdiction over religion, the British monarch is the supreme head and administrator of the Church of England.
What answer can we give to those who insist that such different things are similar? We can only say the same thing to those who insist that a government in which all power is vested in the hands of persons periodically elected by the people is an aristocracy, a monarchy, or a despotism.
