The Monroe Doctrine, announcing in a broad way the separation of the New world from the Old, was the first distinctively American doctrine in international relations. The immediate background of the doctrine was the claims of Russia on the northwest coast of North America and the struggle of the Latin American countries for independence. President Monroe seized the opportunity created by these two issues to announce that the Western Hemisphere was no longer to be considered subject to European conquest or colonization. Some twenty-two years later President Polk reiterated and elaborated upon these principles. In the course of time the Monroe Doctrine ceased to be a unilateral principle and became accepted by other nations. The following is from President Monroe's Seventh Annual Message to Congress, December 2, 1823.
The occasion has been judged proper for asserting, as a principle in which the rights and interests of the United States are involved, that the American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers....
Of events in that quarter of the globe (Europe), with which we have so much intercourse and from which we derive our origin, we have always been anxious and interested spectators. The citizens of the United States cherish sentiments the most friendly in favor of the liberty and happiness of their fellowmen on that side of the Atlantic. In the wars of the European powers in matters relating to themselves we have never taken any part, nor does it comport with our policy so to do. It is only when our rights are invaded or seriously menaced that we resent injuries or make preparation for our defense. With the movements in this hemisphere we are of necessity more immediately connected, and by causes which must be obvious to all enlightened and impartial observers. The political system of the allied powers is essentially different in this respect from that of America. This difference proceeds from that which exists in their respective Governments; and to the defense of our own, which has been achieved by the loss of so much blood and treasure, and matured by the wisdom of their most enlightened citizens, and under which we have enjoyed unexampled felicity, this whole nation is devoted.
We owe it, therefore, to candor and to the amicable relations existing between the United States and those powers to declare that we should consider any attempt on their part to extend their system to any portion of this hemisphere as dangerous to our peace and safety. With the existing colonies or dependencies of any European power we have not interfered and shall not interfere. But with the Governments who have declared their independence and maintained it, and whose independence we have, on great consideration and on just principles, acknowledged, we could not view any interposition for the purpose of oppressing them, or controlling in any other manner their destiny, by any European power in any other light than as the manifestation of an unfriendly disposition toward the United States.
In the war between those new Governments and Spain we declared our neutrality at the time of their recognition, and to this we have adhered and shall continue to adhere, provided no change shall occur which, in the judgment of the competent authorities of this Government, shall make a corresponding change on the part of the United States indispensable to their security.
The late events in Spain and Portugal show that Europe is still unsettled. Of this important fact no stronger proof can be adduced than that the allied powers should have thought it proper, on any principle satisfactory to themselves, to have interposed by force in the internal concerns of Spain. To what extent such interposition may be carried, on the same principle, is a question in which all independent powers whose governments differ from theirs are interested, even those most remote, and surely none more so than the United States.
Our policy in regard to Europe, which was adopted at an early stage of the wars which have so long agitated that quarter of the globe, nevertheless remains the same, which is, not to interfere in the internal concerns of any of its powers; to consider the government de facto as the legitimate government for us; to cultivate friendly relations with it, and to preserve those relations by a frank, firm, and manly policy, meeting in all instances the just claims of every power, submitting to injuries from none. But in regard to these continents circumstances are eminently and conspicuously different. It is impossible that the allied powers should extend their political system to any portion of either continent without endangering our peace and happiness, nor can anyone believe that our southern brethren, if left to themselves, would adopt it of their own accord. It is equally impossible, therefore that we should behold such interposition in any form with indifference. If we look to the comparative strength and resources of Spain and those new Governments, and their distance from each other, it must be obvious that she can never subdue them. It is still the true policy of the United States to leave the parties to themselves, in the hope that other powers will pursue the same course....
Extract From
President Polk's First Annual Message
to Congress, December 2, 1845
This message of Polk's was second in importance only to the original Monroe Doctrine. It inaugurated a new era in the history of the doctrine, and was closely connected with Polk's policy toward Oregon and Texas.
....The rapid extension of our settlements over our territories heretofore unoccupied, the addition of new States to our Confederacy, the expansion of free principles, and our rising greatness as a nation are attracting the attention of the powers of Europe, and lately the doctrine has been broached in some of them of a "balance of power" on this continent to check our advancement, The United States, sincerely desirous of preserving relations of good understanding with all nations, can not in silence permit any European interference on the North American continent, and should any such interference be attempted will be ready to resist it at any and a1l hazards.
It is well known to the American people and to all nations that this Government has never interfered with the relations subsisting between other governments. We have never made ourselves parties to their wars or their alliances, we have not sought their territories by conquest, we have not mingled with parties in their domestic struggles; and believing our own form of government to be the best, we have never attempted to propagate it by intrigues, by diplomacy, or by force. We may claim on this continent a like exemption from European interference.
The nations of America are equally sovereign and independent with those of Europe. They possess the same rights, independent of all foreign interposition, to make war, to conclude peace, and to regulate their internal affairs. The people of the United States can not, therefore, view with indifference attempts of European powers to interfere with the independent action of the nations on this continent. The American system of government is entirely different from that of Europe. Jealousy among the different sovereigns of Europe, lest any one of them might become too powerful for the rest, has caused them anxiously to desire the establishment of what they term the "balance of power." It can not be permitted to have any application on the North American continent, and especially to the United States.
We must ever maintain the principle that the peop1e of this continent alone have the right to decide their own destiny. Should any portion of them, constituting an independent state, propose to unite themselves with our Confederacy, this will be a question for them and us to determine without any foreign interposition. We can never consent that European powers shall interfere to prevent such a union because it might disturb the "balance of power" which they may desire to maintain upon this continent. 'Near a quarter of a century ago the principle was distinctly announced to the world, in the annual message of one of my predecessors that―
"The American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers."
This principle will apply with greatly increased force should any European power attempt to establish any new colony in North America. In the existing circumstances of the world the present is deemed a proper occasion to reiterate and reaffirm the principle avowed by Mr. Monroe and to state my cordial concurrence in its wisdom and sound policy. The reassertion of this principle, especially in reference to North America, is at this day but the promulgation of a policy which no European power should cherish the disposition to resist. Existing rights of every European nation should be respected, but it is due alike to our safety and our interests that the efficient protection of our laws should be extended over our whole territorial limits, and that it should be distinctly announced to the world as our settled policy that no future European colony or dominion shall with our consent be planted or established on any pat of the North American continent....
