Mills County

Mills County is an administrative county in southwestern Iowa comprising several towns and rural communities. The region spans rolling terrain shaped by the Missouri River, which forms its western boundary.

The county was established in 1851 and named after Major Frederick Mills, an officer from the early American era. The first permanent settlement arrived in 1846 when Rushville was founded by members of a religious community.

The settlement of Rushville marked the first permanent community in 1846, founded by members of the Church of Jesus Christ of Latter-day Saints.

Glenwood serves as the county seat and is the center for public services in the region. Interstate 29 runs through the area, providing straightforward connections to larger cities like Omaha and Council Bluffs.

The county sits directly adjacent to the Omaha region and offers a blend of rural living with proximity to a metropolitan area. This position makes it a transition zone between countryside and urban centers.
