The Early 20th Century United States refers to the period from around 1900 to 1940, marked by significant social, political, and economic changes that shaped the modern American landscape. This era saw a surge in immigration and migration, which transformed urban centers and created a diverse population, while also prompting shifts in labor practices, social reforms, and civil rights movements.
