Decade by Decade Timeline of the 1800s

Several hundred years after Europeans began arriving in North America, the United States of America fought for and won its freedom as an independent country. But it wasn't until the 1800s that a series of events would propel this largely agrarian land toward its status as a powerful and unified nation.

Key to this growth was the idea of "manifest destiny," a term credited to newspaper editor John O'Sullivan (1813–1895) in 1845 that outlined the colonialist belief that America was destined—ordained by God, in fact—to expand the virtues of its democratic founding westward until it held every inch of land from shore to shore.

Yet the Civil War, which took place in the middle of the century, resulted in part as a challenge to this idea​. The war left the nation teetering on the edge of complete fracture.

The 1800s were also a time of great intellectual and technical progress, with many people acquiring astonishing economic gains.
