United States, 1865–1898
Democracy · Republic · North America · Imperial Zenith era
Gilded-Age America: rapid industrialization, mass immigration and westward expansion under a democracy marked by machine politics and vast new fortunes.
In the decades after the Civil War the United States industrialized at extraordinary speed, absorbed mass immigration, settled the West and became the world’s largest economy. Democratic institutions coexisted with party machines, patronage, corporate power and, in the South, the rollback of Reconstruction and the imposition of racial segregation. The period ended with overseas expansion in the war of 1898.
