The treaty did not attempt a precise description or boundary of the territory ceded. In the treaty of San Ildefonso general terms only are used. It speaks of Louisiana as of "the same extent that it now has in the hands of Spain, and that it had when France possessed it, and such as it should be after the treaties subsequently entered into between Spain and the other States." The treaty with the United States describes the land as "the said territory, with all its rights and appurtenances, as fully and in the same manner as have been acquired by the French Republic, in virtue of the above-mentioned treaty concluded with his Catholic Majesty."
The Court at Madrid was astounded when it heard of the cession to the United States. Florida was left hemmed in and an easy prey in the first hostilities. Spain filed a protest against the transfer, claiming that by express provision of the articles of cession to her, France was prohibited from alienating it without Spanish consent. The protest being ignored, Spain began a course of unfriendly proceedings against the United States. Hostile acts on her part were continued to such an extent that a declaration of war on the part of this country would have been justified. We relied upon the French to protect our title. At length, without any measures of force, the cavilling of Spain ceased and she acquiesced in the transfer.
Upon being confronted with the proposition of sale by Marbois, our Ministers were dazzled. They recognized the vast importance of an acceptance, yet felt their want of authority. With a political prescience and broad patriotism they overstepped all authority and concluded the treaty for the purchase of this magnificent domain. Authorized to purchase a small island and a coaling-place, they contracted for an empire. The treaty of settlement was looked upon by our representatives as a stroke of state. When the negotiations were consummated and the treaties signed and delivered, Mr. Livingston said: "We have lived long, and this is the fairest work of our lives. The treaty we have just signed will transform a vast wilderness into a flourishing country. From this day the United States becomes a first-class power. The articles we have signed will produce no tears, but ages of happiness for countless human beings." Time has verified these expressions. At the same period, the motives and sentiment of Bonaparte were bodied forth in the sentence: "I have given to England a maritime rival that will sooner or later humble her pride."
The acquisition was received with merited and general applause. Few objections were made. The only strenuous opposition arose from some Federalists, who could see no good in any act of the Jeffersonian administration, however meritorious it might be. Out of the territory thus acquired have been carved Louisiana, Missouri, Kansas, Arkansas, Nebraska, Iowa, North Dakota, South Dakota, Montana, and the largest portion of Minnesota, Wyoming, and Colorado. They now form the central section of the United States, and are the homes of millions and the sources of countless wealth.
It is possible here to notice but briefly the vast and permanent political and economical consequences to the United States of this purchase. The party which performed this service came into power as the maintainer of voluntary union. The soul of the strict construction party was Thomas Jefferson. Inclined to French ideas, he had been for several years previous to the founding of our Constitution imbibing their extreme doctrines. No sooner did he return than he discerned, with the keen glance of genius, what passed Hamilton and Adams unobserved, the key to the popular fancy. He knew precisely where the strength of the Federalists lay, and by what means alone that strength could be overpowered.
Coming into office as the champion of "State-rights and strict construction," it was beyond his power to give theoretical affirmance to this transcendent act of his agents. His own words reveal his anomalous situation: "The Constitution has made no provision for our holding foreign territory, still less for incorporating foreign nations into our Union. The executive, in seizing the fugitive occurrence which so much advances the good of their country, have done an act beyond the Constitution. The Legislature, in casting behind metaphysical subtleties and risking themselves like faithful servants, must ratify and pay for it, and throw themselves on their country for doing for them unauthorized what we know they would have done for themselves had they been in a position to do it." "Doing for them unauthorized what we know they would have done for themselves" was the policy of the Federalists, and the very ground upon which Mr. Jefferson had denounced their policy and defeated them. The purchase was, in fact, quite within those implied powers of the Constitution which had always been contended for by the Federalists, and such leaders as Hamilton and Morris acknowledged this. Under the strict construction theory, not only could there be no authority for such an acquisition of territory without the consent of the several States denominated "part of the original compact," but the manifest and necessary consequences of this accession, in its effects upon the Union and upon the balance of power within the Government, were overwhelming to such an extent as to amount almost to a revolution.
This event may be looked upon as a revolution in the direction of unification and the impairment of the powers of the several States, brought about by the very party which had undertaken to oppose such tendencies. The territory gained stretches over a million square miles equal in area to the territory previously comprised in the Union, and twice as large as that actually occupied by the original thirteen States. Compared with this innovation, the plans of the Federalists for strengthening the Central Government were inconsiderable. A new nation was engrafted on the old, and neither the people of the several States nor their immediate representatives were questioned; but by a treaty the President and the Senate changed the whole structure of the territory and modified the relations of the States. Thenceforth, the Louisiana purchase stood as a repudiation by their own champions of the strict construction fallacies. Thenceforth, the welfare of the country stands above party allegiance. The right to make purchases was thereafter, by general acquiescence of all political parties, within the powers of the Federal Government. Indeed, it became manifest that implied as well as expressed powers accrued to the National Government.
The territory of Louisiana proved a fruitful soil for the spread of slavery, nor was it less productive of struggles and strife over the admission of States carved therefrom. The Civil War has pacified the jarring elements and left to be realized now the beneficent results of the empire gained. With Louisiana the United States gained control of the entire country watered by the Mississippi and its effluents. With the settlement of the western country, the Mississippi river assumed its normal function in the national development, forming out of that region the backbone of the Union. The Atlantic and Pacific States can never destroy the Union while the Central States remain loyal. Thus do we see the basis of our governmental existence removed from the narrow strip along the Atlantic to the far larger central basin; binding by natural ligaments a union far less secure on mere constitutional or artificial connections. Thus have the intentions of its projectors been fulfilled, the peace of our nation secured, a spirit of confidence in our institutions diffused, and enterprise and prosperity advanced. The purchase was an exercise of patriotism unrestrained and unbiased by considerations unconnected with the public good. It curbed the impulse of State jealousies, secured to the Union unwonted prestige, and discovered the latent force and broad possibilities of our national system.
