the Western territory sufficiently known to the public. 6. “To guarantee to every State in the Union a republican form of government; to protect each of them against invasion; and on application of the legislature, or of the executive (when the legislature cannot be convened), against domestic violence. “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 monarchial 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 shows 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 Amphictyons. “ 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 enterprising 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 further 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 choose 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 antirepublican Constitutions; a restriction which, it is presumed, will hardly be considered as a grievance.
