The Long Century is a history site focused on the United States from 1850 to 1900, a period of upheaval, conflict, and rapid change. The site looks at the Civil War, Reconstruction, westward expansion, labor unrest, politics, industrial growth, and the social pressures that shaped the country in the late nineteenth century.

The goal is to make this era readable without flattening it. These articles are meant to be long-form, direct, and grounded in the people and events that made the period. Some pieces focus on major turning points. Others look at smaller subjects, forgotten figures, or details that are usually left out of the standard summary.
