1900-1920:
Progressive Era
A period of varied reforms that took place throughout the US
over the first two decades of the 20th century. While much of that
change was enacted by the U.S. Congress under the leadership of
three consecutive presidents— Theodore Roosevelt, William
Howard Taft, and Woodrow Wilson— it was also a movement that
generated a variety of changes at the state and local levels as well. (1 Jan 1900 Jahr – 1 Jan 1920 Jahr)
