Article 4, Section 4
James Madison, Federalist, no. 43, 291--9523 Jan. 1788
In a confederacy founded on republican principles, and composed of republican members, the superintending government ought clearly to possess authority to defend the system against aristocratic or monarchical innovations. The more intimate the nature of such a Union may be, the greater interest have the members in the political institutions of each other; and the greater right to insist that the forms of government under which the compact was entered into, should be substantially maintained. But a right implies a remedy; and where else could the remedy be deposited, than where it is deposited by the Constitution? Governments of dissimilar principles and forms have been found less adapted to a federal coalition of any sort, than those of a kindred nature. "As the confederate republic of Germany," says Montesquieu, "consists of free cities and petty states subject to different Princes, experience shews us that it is more imperfect than that of Holland and Switzerland." "Greece was undone" he adds, "as soon as the King of Macedon obtained a seat among the Amphyctions." In the latter case, no doubt, the disproportionate force, as well as the monarchical form of the new confederate, had its share of influence on the events. It may possibly be asked what need there could be of such a precaution, and whether it may not become a pretext for alterations in the state governments, without the concurrence of the states themselves. These questions admit of ready answers. If the interposition of the general government should not be needed, the provision for such an event will be a harmless superfluity only in the Constitution. But who can say what experiments may be produced by the caprice of particular states, by the ambition of enterprizing leaders, or by the intrigues and influence of foreign powers? To the second question it may be answered, that if the general government should interpose by virtue of this constitutional authority, it will be of course bound to pursue the authority. But the authority extends no farther than to a guaranty of a republican form of government, which supposes a pre-existing government of the form which is to be guaranteed. As long therefore as the existing republican forms are continued by the States, they are guaranteed by the Federal Constitution. Whenever the states may chuse to substitute other republican forms, they have a right to do so, and to claim the federal guaranty for the latter. The only restriction imposed on them is, that they shall not exchange republican for anti-republican Constitutions; a restriction which it is presumed will hardly be considered as a grievance.
A protection against invasion is due from every society to the parts composing it. The latitude of the expression here used, seems to secure each state not only against foreign hostility, but against ambitious or vindictive enterprizes of its more powerful neighbours. The history both of antient and modern confederacies, proves that the weaker members of the Union ought not to be insensible to the policy of this article.
Protection against domestic violence is added with equal propriety. It has been remarked that even among the Swiss Cantons, which properly speaking are not under one government, provision is made for this object; and the history of that league informs us, that mutual aid is frequently claimed and afforded; and as well by the most democratic, as the other Cantons. A recent and well known event among ourselves, has warned us to be prepared for emergencies of a like nature.
At first view it might seem not to square with the republican theory, to suppose either that a majority have not the right, or that a minority will have the force to subvert a government; and consequently that the foederal interposition can never be required but when it would be improper. But theoretic reasoning in this, as in most other [Volume 4, Page 563] cases, must be qualified by the lessons of practice. Why may not illicit combinations for purposes of violence be formed as well by a majority of a State, especially a small State, as by a majority of a county or a district of the same State; and if the authority of the State ought in the latter case to protect the local magistracy, ought not the foederal authority in the former to support the State authority? Besides, there are certain parts of the State Constitutions which are so interwoven with the Foederal Constitution, that a violent blow cannot be given to the one without communicating the wound to the other. Insurrections in a State will rarely induce a foederal interposition, unless the number concerned in them, bear some proportion to the friends of government. It will be much better that the violence in such cases should be repressed by the Superintending power, than that the majority should be left to maintain their cause by a bloody and obstinate contest. The existence of a right to interpose will generally prevent the necessity of exerting it.
Is it true that force and right are necessarily on the same side in republican governments? May not the minor party possess such a superiority of pecuniary resources, of military talents and experience, or of secret succours from foreign powers, as will render it superior also in an appeal to the sword? May not a more compact and advantageous position turn the scale on the same side against a superior number so situated as to be less capable of a prompt and collected exertion of its strength? Nothing can be more chimerical than to imagine that in a trial of actual force, victory may be calculated by the rules which prevail in a census of the inhabitants, or which determine the event of an election! May it not happen in fine that the minority of CITIZENS may become a majority of PERSONS, by the accession of alien residents, of a casual concourse of adventurers, or of those whom the Constitution of the State has not admitted to the rights of suffrage? I take no notice of an unhappy species of population abounding in some of the States, who during the calm of regular government are sunk below the level of men; but who in the tempestuous scenes of civil violence may emerge into the human character, and give a superiority of strength to any party with which they may associate themselves.
In cases where it may be doubtful on which side justice lies, what better umpires could be desired by two violent factions, flying to arms and tearing a State to pieces, than the representatives of confederate States not heated by the local flame? To the impartiality of Judges they would unite the affection of friends. Happy would it be if such a remedy for its infirmities, could be enjoyed by all free governments; if a project equally effectual could be established for the universal peace of mankind.
Should it be asked what is to be the redress for an insurrection pervading all the States, and comprizing a superiority of the entire force, though not a constitutional right; the answer must be, that such a case, as it would be without the compass of human remedies, so it is fortunately not within the compass of human probability; and that it is a sufficient recommendation of the Foederal Constitution, that it diminishes the risk of a calamity, for which no possible constitution can provide a cure.
Among the advantages of a confederate republic enumerated by Montesquieu, an important one is, "that should a popular insurrection happen in one of the States, the others are able to quell it. Should abuses creep into one part, they are reformed by those that remain sound."
