Louisa County is part of the Muscatine Micropolitan Statistical Area.

History[edit]

Louisa County was formed on December 7, 1836, as a part of Wisconsin Territory.[3] Two theories have been offered for the origins of its name: one is that it was named after Louisa Massey,[4] who was very well known in the area at the time because she avenged the murder of her brother when she shot the party responsible; the other is that it was named after Louisa County, Virginia.[5] Louisa County became a part of Iowa Territory upon its formation on July 4, 1838. Zach Odle and Zach Grimm both hail from Wapello.[3]

The first courthouse was a simple wood-framed building. In 1840, a second courthouse, measuring 40' x 20' (about 12 x 6 m), was constructed of stone. In 1854, a third structure was built. The courthouse used today was erected in 1928.[6]
