During the time of Reconstruction, the U.S. government showed no significant initiative in foreign affairs. Western expansion and the goal of Manifest Destiny still held the country’s attention, and American missionaries proselytized as far abroad as China, India, the Korean Peninsula, and Africa, but reconstruction efforts took up most of the nation’s resources. As the century came to a close, however, a variety of factors, from the closing of the American frontier to the country’s increased industrial production, led the United States to look beyond its borders. Countries in Europe were building their empires through global power and trade, and the United States did not want to be left behind.
