About Polk County
Polk County Timeline
Polk County, Iowa has a rich and diverse history that stretches back thousands of years. Native American tribes such as the Sauk and Meskwaki inhabited the region before European settlement. In the early 1800s, the area was explored by French trappers and later became part of the Louisiana Purchase in 1803. Following the Black Hawk War in 1832, the Sauk and Meskwaki were forcibly removed from the county.
Polk County was officially established on January 13, 1846, and was named after President James K. Polk. Des Moines, which is now the state capital and largest city in Iowa, became the county seat. In its early years, Polk County developed as an agricultural center, with farms and small communities dotting the landscape.
The county experienced significant growth with the arrival of the railroad in the late 19th century. The Chicago, Rock Island and Pacific Railroad and the Chicago and North Western Railway helped establish Des Moines as a transportation hub, leading to increased industrialization and economic development. The city became a leading center for insurance and financial services, which had a lasting impact on Polk County's economy.
Throughout the 20th century, Polk County continued to evolve, with a growing population and expanding urban areas. Major landmarks like the Iowa State Capitol, the Principal Riverwalk, and the Des Moines Art Center have further solidified Des Moines' position as a regional cultural and economic hub. Today, Polk County is known for its diverse economy, strong education system, and vibrant cultural scene, making it a desirable place to live, work, and visit.
