American entry into the ranks of colonial powers as an aftermath of the Spanish American War was sudden, unexpected, and, chronologically speaking, late in the game of colonial empire building. Prior to the last decade of the 19th century, United States had shown no lack of territorial acquisitiveness, but national expansion was exclusively in terms of organic growth of the whole nation. There was no interest in, nor attempts at building a “colonial empire” along conventional lines in which territories and their inhabitants were placed “permanently” under control but not under a shared set of political institutions. Up to 1898, all “civilized” inhabitants of new territories were immediately given the status of United States citizens with all rights and privileges thereof.
