It was established in 1851 and became an organized county, March 7, 1853, by an act of the Fourth General Assembly, which enactment also appointed Abram Fletcher, Charles Wolcott and A. D. Jones, respectively from Fremont, Mills and Pottawattamie counties, as Commissioners to locate the county seat, the name of which was to be Magnolia, and who were to meet early in March for such purpose. The county derived its name in honor of the Ninth President of the United States - William Henry Harrison.
The Commissioners selected the southeast corner of T80, R43, section 32 and then gave to the 160 acres thus selected the name of “Magnolia” and the Organizing Sheriff called an election on the first Monday of April, the same year - 1853, at which time a full corps of county officers was elected. There were other locations claiming the county seat Daniel Brown wanted it at what he platted and called Calhoun, while another faction wanted it located where Logan now stands, or on the opposite side of the Boyer River.
