History of the United States (1865–1917)
The history of the United States from 1865 to 1917 was marked by the Reconstruction era, the Gilded Age, and the Progressive Era, and includes the rise of industrialization and the resulting surge of immigration in the United States.
The United States of America
This period of rapid economic growth and soaring prosperity in the Northern United States and the Western United States saw the U.S. become the world's dominant economic, industrial, and agricultural power. The average annual income (after inflation) of non-farm workers grew by 75% from 1865 to 1900, and then grew another 33% by 1918.[1]
With a victory in 1865 over the Southern Confederate States in the Civil War, the United States became a united nation with a stronger national government. Reconstruction brought the end of legalized slavery plus citizenship for the former slaves, but their new-found political power was rolled back within a decade, and they became second-class citizens under a "Jim Crow" system of deeply pervasive segregation that would stand for the next 80–90 years. Politically, during the Third Party System and Fourth Party System the nation was mostly dominated by Republicans (except for two Democratic presidents). After 1900 and the assassination of President William McKinley, the Progressive Era brought political, business, and social reforms (e.g., new roles for and government expansion of education, higher status for women, a curtailment of corporate excesses, and modernization of many areas of government and society). The Progressives worked through new middle-class organizations to fight against the corruption and behind-the-scenes power of entrenched, state political party organizations and big-city "machines". They demanded—and won—women's right to vote, and the nationwide prohibition of alcohol 1920–1933.
In an unprecedented wave of European immigration, 27.5 million new arrivals between 1865 and 1918[2] provided the labor base necessary for the expansion of industry and agriculture, as well as the population base for most of fast-growing urban America.
By the late nineteenth century, the United States had become a leading global industrial power, building on new technologies (such as the telegraph and steel), an expanding railroad network, and abundant natural resources such as coal, timber, oil, and farmland, to usher in the Second Industrial Revolution.
It was also during this period that the United States began to emerge as a global superpower. The U.S. easily defeated Spain in 1898, which unexpectedly brought a small empire. Cuba quickly was given independence, and the Philippines eventually became independent in 1946. Puerto Rico (and some smaller islands) became permanent U.S. territories, as did Alaska (added by purchase in 1867). The independent Republic of Hawaii was annexed by the U.S. as a territory in 1898.
