Afterwards the "Monroe doctrine"--deriving its name from a message by President Monroe in 1823--was given the meaning that the United States would not tolerate any interference with the affairs of the American continent by Europe. Finally the "Monroe doctrine," which had begun with an affirmation of America's non-participation in European affairs, and had developed into a declaration against European interference with American affairs, took its present form, which is, in effect, that over all America the United States has a paramount interest which must not be questioned, and that as regards the rest of the world she claims an equal voice with other Powers. Yet, though that is the actual position, there is still an idea in some minds that the Monroe doctrine is an instrument of humbleness by which the United States claims the immunity of America from foreign interference and guarantees foreign countries from American interference. It will be of value to recall, in illustration of the rapid growth of an aggressive national pride in the United States, the circumstances which led up to Mr. President Monroe's formal message in 1823. The dawn of the nineteenth century found the young American nation, after about a quarter of a century's existence, fairly on her feet; able to vindicate her rights abroad by a war against the Barbary pirates: given by the cession of Louisiana from France, a magnificent accession of territory. The Empire of Spain was crumbling to pieces, and between 1803 and 1825 the Latin-American Republics in South and Central America were being established on the ruins of that Empire. Spain, her attention engaged in European wars, was able to do little or nothing to assert herself against the rebellious colonies. But in 1815, Napoleon having been vanquished, the Holy Alliance in Europe attempted to reassert the old power of the European monarchies. The terror of Napoleon's army had forced the kings of the earth into a union which forgot national differences and was anxious only to preserve the Divine Right of Kings. The formation of this Holy Alliance was viewed with suspicion and dislike in the United States, and when in 1823 the Alliance raised the question of joint action by European monarchies to restore Spanish rule in South America, the United States responded with Monroe's famous message forbidding any European interference on the continent of America. Such European colonies as already existed would be tolerated, and that was all. The message stated: "The American continents by the free and independent conditions which they have assumed are henceforth not to be considered as subjects for future colonisation by any European Power. "We could not view any interposition for purpose of oppressing them or controlling in any other manner their destiny by any European Power in any other way than as the manifestation of an unfriendly disposition towards the United States."
