Welcome to Adams County

Adams County was established by the state legislature in 1851 and named in honor of the second President of the United States, John Adams, or his son, the sixth President, John Quincy Adams (sources differ). The county was finally organized and separated from Pottawattamie County on March 12, 1853. Its original size was later reduced by the creation of Montgomery and Union counties.

The first county seat was Quincy. In 1872, it was moved to Corning.
