What happens when a nation begins to believe that the future can be better than the past—and that it has the power to make it so?

At the dawn of the twentieth century, America was being transformed at breathtaking speed. Railroads, factories, enormous corporations, new technologies, and rapidly growing cities were creating wealth and opportunity on a scale previous generations could scarcely have imagined. But beneath that remarkable progress were troubling realities: dangerous workplaces, child labor, urban poverty, political corruption, enormous concentrations of wealth, and growing conflict between workers and corporations.

Americans increasingly began asking whether progress should mean more than simply becoming richer and more powerful.

In this episode of The Empire: A 250 Year American Story, we explore the Progressive Era and the revolutionary idea that society itself could be deliberately improved. Reformers, journalists, Christians, labor organizers, intellectuals, and politicians began challenging assumptions that had governed American life for generations. Some sought to reform capitalism. Others believed Christianity demanded greater engagement with poverty and injustice. Still others questioned capitalism itself.

Along the way, we meet remarkable figures such as Jane Addams, Eugene V. Debs, Theodore Roosevelt, and the journalists who exposed some of industrial America’s darkest realities. We also examine competing philosophies—including the Social Gospel, Social Darwinism, and socialism—that offered dramatically different visions of what “progress” actually meant.

But the Progressive Era also carried a warning. The conviction that society could be improved sometimes produced extraordinary reforms—and sometimes opened the door to coercion, prejudice, and terrible injustice.

This is the story of the moment Americans stopped merely hoping for a better future and increasingly began believing they could build one.

This post is part of our collection and series The Empire: A 250 Year American Story. Each week for the duration of 2026, new episodes will release, telling the unique, complex, and fascinating story of America’s history.
