In view of this powerful sentiment swaying a great people, as well as their government, it is not surprising that Congress is often called upon to apply its principles; and it therefore becomes more and more important that it should be well understood by people, as well as Congress, in respect to its origin and purpose.

In the message of President Monroe to Congress, at the commencement of the session of 1823-24, the following passages occur:

"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 to do so. It is only when our rights are invaded, or seriously menaced, that we resent injuries, or make preparations for defence. 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 defence 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 such 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, in any other light, than as the manifestation of an unfriendly disposition towards the United States."

"It is impossible that the allied powers should extend their political sytem to any portion of either continent, without endangering our peace and happiness.

"It is equally impossible, that we should behold such interposition in any form with indifference."

Lest there may be some misapprehension, as to the political circumstances, which called for the promulgation of this "Monroe Doctrine," let us for a moment review the events which gave color and importance to the political environments of that date which elicited from President Monroe this now famous declaration.

In the year 1822 the allied sovereigns held their Congress at Verona. The great subject of consideration was the condition of Spain; that country being then under the Cortes or representatives of the Revolutionists. The question was, whether or not Ferdinand should be re-instated in all his authority by the intervention of foreign powers.

Russia, Prussia, France, and Austria, were inclined to that measure; England dissented and protested, but the course was agreed upon; and France, with the consent of these other continental powers, took the conduct of the operation into her own hands. In the spring of 1823, a French army was sent into Spain. Its success was complete; the popular government was overthrown, and Ferdinand was re-instated and re-established in all his power. This invasion was determined on and undertaken precisely on the doctrines which the allied monarchs had proclaimed the year before at Laybach; that is, that they had the right to interfere in the concerns of another State, and reform its government, "in order to prevent the effect of its bad example" (this bad example, be it remembered, always being the example of free government by the people). Now having put down the example of the Cortes, in Spain, it was natural to inquire, with what eyes they should look on the Colonies of Spain, that were following still worse examples. Would King Ferdinand and his allies be content with what had been done in Spain itself, or would he solicit their aid and would they grant it, to subdue his rebellious American colonies?
