Pivotal Decades: The United States, 1900-1920
Contemporary American began in the first two decades of this century.
These were the years in which two of our greatest presidentsۥTheodore Roosevelt and Woodrow Wilsonۥtransformed the office into the center of power; in which the United States entered the world stage and fought its first overseas war; in which the government's proper role in the economy became a public question; and in which reform became an imperative for muckraking reporters, progressive politicians, social activists, and writers.
