The story so far

Union Township, in brief

Wikipedia doesn’t have a history of Union Township yet. The photos, dates and memories neighbors add here are how it gets written.

Union Township is a township in Harrison County, Missouri, United States. At the 2020 census, its population was 388. Union Township was erected in 1858. The township was named for the federal union, since a large share of the residents were pro-Union during the Civil War.

Between the 2010 and 2020 censuses its population fell from 411 to 388 (-6%).
