As the 19th century closed and the 20th century began, the United States found itself at a crossroads, poised between its past as a burgeoning agricultural nation and its future as a global industrial power. The turn of the century, marked by technological breakthroughs and rapid urbanization, also heralded a seismic shift in American demographics. The steady influx of immigrants, drawn from across Europe, Asia, and Latin America, brought new faces, cultures, and ideas that would transform the nation's identity. This moment in history was not only an era of opportunity for many but also one of intense social and political change that set the stage for decades of conflict and growth.
