History of Des Moines Iowa begins with the Des Moines River, Raccoon River, Indigenous homelands, Fort Des Moines, Captain James Allen, Polk County, state capital status, railroads, coal mining, insurance, publishing, government, and riverfront growth. The city sits where the Des Moines and Raccoon rivers meet in central Iowa. Because of that location, Des Moines grew as a military post, settlement, capital city, transportation hub, and statewide business center.
Fort Des Moines was established in 1843 at the rivers’ meeting point. Meanwhile, soldiers built cabins and support buildings near the water. Therefore, the fort became the starting point for the future city.
Native title to the Fort Des Moines area expired in 1845. Afterward, the land opened for settlement. As a result, the military post area quickly became a growing townsite.
A town was platted at the site in 1846. Additionally, the first frame building went up that July. Later, the first brick building appeared in 1848.
The City of Fort Des Moines incorporated in September 1851. However, the original name did not last forever. Local growth soon pushed the community toward a shorter civic identity.
Fort Des Moines officially became the City of Des Moines on February 16, 1857. Because of that change, the city separated its identity from the fort. Still, the military-post story remained central to local history.
Governor James Grimes officially designated Des Moines as Iowa’s capital in October 1857. Meanwhile, state government brought offices, workers, visitors, and influence. Therefore, capital status transformed the city’s future.
The Des Moines Valley Railroad reached the city in 1866. Additionally, rail access strengthened trade and transportation. Over time, railroads helped Des Moines grow beyond its riverfront beginnings.
Iowa’s General Assembly chose Des Moines as the new capital city. Later, the current Capitol became the city’s most recognizable government landmark. Today, its gold dome remains a central symbol of Iowa.
B. F. Allen built Terrace Hill in 1869 at a cost of $250,000. Moreover, the home reflected wealth from the city’s expanding economy. Today, it remains tied to Iowa’s public and architectural history.
The Des Moines Public Library was chartered in December 1866. Meanwhile, the city’s newspaper history began even earlier in 1849. Because of that, records and local reporting became important community resources.
The Des Moines Historical Society preserves and shares local history. Additionally, the State Historical Society of Iowa serves as Iowa’s official historical repository. Therefore, residents still have strong resources for studying the city’s past.
Des Moines history is rooted in rivers, military settlement, state government, railroads, publishing, and preservation. However, capital status gave the city its strongest statewide role. Today, Des Moines remains Iowa’s political center and a major Midwestern business hub.
