Adams County, Iowa, located in the southwestern part of the state, has a rich history that traces back to the early 19th century. The county was officially established on January 15, 1851, and was named after John Quincy Adams, the sixth President of the United States. Prior to European settlement, the area was home to Native American tribes, including the Sac and Fox tribes.

The first settlers arrived in Adams County in the early 1850s, drawn by the fertile soils and opportunity for farming. The county quickly developed an agricultural economy, with settlers cultivating corn, wheat, and oats. As more settlers arrived, small towns and communities began to emerge, providing necessary services and creating a sense of community.

One significant event in Adams County's history was the establishment of Corning as the county seat in 1864. This decision sparked controversy and led to a legal battle, as other towns in the county vied for the title. After a series of court cases, Corning ultimately won and became the permanent county seat, solidifying its importance in the region.
