What is Pan-Americanism? The term itself is new. It appears to have been employed first by the New York Evening Post in discussions relating to the International American Conference which was held at Washington in 1889–1890. It was used in imitation doubtless of such terms as Pan-Slavism, Pan-Hellenism, and Pan-Islamism, which, along with numerous combinations of the sort, became current during the third quarter of last century. The new term was quickly admitted into the columns of other newspapers, and, as in the course of a few years its use became general, it found its way into the editions of the dictionaries and encyclopedias which subsequently appeared. To such works of reference inquirers who have but a vague notion of its meaning are most likely to turn for their first instruction on the subject. Unfortunately, however, from this source but little enlightenment is to be obtained.
