To students of international relations it has become almost a commonplace that among the most significant and permanent results of the World War has been the changed international status of the republics of Latin America. As a result of the war and post-war developments in these states, the traditional New World isolation in South America, as well as in North America, is a thing of the past. To our leading sister republics is no longer applicable the half-contemptuous phrase, current in the far-off days before 1914, that Latin America stands on the margin of international life. The new place in the comity of nations won by a number of these states is evidenced—to take one of the most obvious examples—by the raising of the legations of certain non-American powers to the rank of embassies, either during or immediately after the war. In the case of Brazil, for instance, where prior to 1914 only the United States maintained an ambassador, at the present time Great Britain, France, Italy, Belgium, Portugal, and Japan maintain diplomatic representatives of this rank.Yet all things considered one of the most fruitful developments in the domain of international relations has been the share taken by our southern neighbors in the work of the League of Nations. All of the Latin American republics which severed relations with Germany or declared war against that country were entitled to participate in the Peace Conference. As a consequence, eleven of these states affixed their signatures to the Treaty of Versailles, an action subsequently ratified in all cases except Ecuador.
