Practically all of them were represented at the second.

The appearance of their delegates at these august assemblages of the powers of earth was viewed for a while with mixed feelings.

The attitude of the Great Powers towards them resembled that of parents of the old regime: children at the international table should be "seen and not heard." As a matter of fact, the Hispanic Americans were both seen and heard--especially the latter! They were able to show the Europeans that, even if they did happen to come from relatively weak states, they possessed a skillful intelligence, a breadth of knowledge, a capacity for expression, and a consciousness of national character, which would not allow them simply to play "Man Friday" to an international Crusoe.
The president of the second conference, indeed, confessed that they had been a "revelation" to him.
Hence, as time went on, the progress and possibilities of the republics of Hispanic America came to be appreciated more and more by the world at large.

Gradually people began to realize that the countries south of the United States were not merely an indistinguishable block on the map, to be referred to vaguely as "Central and South America" or as "Latin America." The reading public at least knew that these countries were quite different from one another, both in achievements and in prospects.
Yet the fact remains that, despite their active part in these American and European conferences, the Hispanic countries of the New World did not receive the recognition which they felt was their due.

Their national associates in the European gatherings were disinclined to admit that the possession of independence and sovereignty entitled them to equal representation on international council boards.
