Founded on the principles of religious freedom, America in the 1800s was fertile ground for the expansion of religious movements and all kinds of experiments in spiritual matters. Americans in the 1800s took their religion very seriously. Away from the authority of established churches, the American frontier from upstate New York to the wilds of the Utah territory was a hotbed of new, radical religion based on a personal experience of salvation, direct revelation, and enthusiastic, highly emotional gatherings at camp meetings. At the forefront of the movement to abolish slavery and women's rights, idealistic men and women in the more established Protestant churches heard a new social gospel from an educated and progressive clergy. Meanwhile, large numbers of Catholic immigrants and Jews from Central and Eastern Europe established their own religious institutions in a new land. The religious history of America in the 1800s is rich and diverse and highly influential in the social and political evolution of our country.

While often behind the scenes and hidden from history, women in 1800s America worked side by side with men in building our nation. On the frontier, strong, capable women worked as hard—or harder—than their men-folk, taming the land and raising the crops while shouldering the responsibilities of keeping house and caring for the children. The life of the farm wife in the settled parts of the country was one of sunup to sundown labor in an era with few modern conveniences. And in urban areas, working-class women were a major part of the workforce in an industrializing economy, while middle- and upper-class women influenced America's social movements, supported charities, and helped beautify the gritty cities. In the course of the 1800s, new labor-saving technologies in the home, improved health conditions, greater economic and educational opportunities, and a growing sense of their rights helped to empower women and started the movement toward full equality with men that continues to this day.

In rough frontier cabins, tidy farmhouses, and elegant townhouses, Americans in the 1800s were dedicated to living as well and as comfortably as their circumstances allowed. The American home was a sacred institution, the seat of family life where the patriarch ruled with Mother at his side as guardian of the home, and the children were raised with strict discipline and strong values. Changes in taste and fashion, improvements in technology (indoor plumbing and a host of new labor-saving devices), and social change transformed home and family life in the 1800s, as opportunities for leisure activities and commercially produced consumer goods came within reach of the average American. But the strong American tradition of the sanctity of the home, consumerism, and the importance of a happy family life has its roots in the homes of nineteenth-century Americans.

American society in the 1800s had a rough edge to it. In a nation made up of people of diverse backgrounds and heritage, social controls needed to be strict and enforceable. The extreme economic inequality of America's cities and the wide-open moral code of the frontier led to a culture of crime and violence that still plagues our country. During the 1800s, professional police forces were established in cities, towns, and territories across the continent. On the frontier, "justice" was often swift and severe, with "hanging judges" making their reputations as representatives of the law in a lawless land. Long prison sentences in miserable conditions were the rule for criminals, and many a prisoner might have preferred the option of a quick execution. Before the reform of the legal system—which is an ongoing process—there was definitely a separate law, and a separate standard of penalties, for the rich and for the poor. The evolution of a humane penal system and a fairer protection of all citizens under the law is an important contribution of 1800s America to the modern world.

Life on the American frontier of the 1800s is the stuff of American myth and legend. It was here in the wide-open spaces of the West that the rugged individualism of the American character was refined: in the strong but silent cowboy, the saloon girl with a heart of gold, and the sod-busting pioneer. Faced with the incredible challenges of taming a wilderness, wresting the territory from the Native peoples, and dealing with the hardships of pioneer life, Americans were offered one of the richest opportunities in the history of human kind—the agricultural and mineral resources of a new land. The settling of this land is the story of America, a story of violence, wasted resources, and genocide, as well as heroism, freedom, and incredible opportunity. The Wild West of the 1800s remains for Americans a land of hopes and dreams.

With the principles of democracy firmly established after the War for Independence, Americans in the 1800s took their politics very seriously. As more and more male citizens gained the right to vote, elections became very public, hotly contested, and sometimes even violent. In the cities and towns of America, politicians courted political power and influence among new immigrant communities; buying votes and stuffing ballot boxes was shockingly common. While the major national political issues of foreign policy, taxation, the abolition of slavery, and states' rights took center stage in Congress, Americans split along regional and party lines that still exist in the twenty-first century. Scandals over greed and corruption caused whole city governments to fall, but America also produced some of the greatest statesman and political leaders in its history. Former slaves, poor immigrants, and women demanded their right to vote.

From an isolated and inward-looking new nation clinging to the East Coast, America in the 1800s grew in size, strength, and military might. From the War of 1812 to the century-long campaigns of conquest against Native American peoples, territorial expansion through war with Mexico to the great national tragedy that was the Civil War, American soldiers and sailors forged a tradition of pride and heroism that is part of our national heritage. Sometimes misguided, sometimes truly inspired, nineteenth-century America produced some of the greatest military leaders and witnessed some of the bloodiest battles in our history. Behind the scenes, and often neglected in our official histories, the life of America's citizen soldiers was a tough and brutal one. Patriotism, heroism, and human folly all combine in the story of the roots of America's rise to the status of world military power.
