History
Free Soil's name is believed to reflect the political spirit of the mid-19th century Free Soil Party, which opposed the expansion of slavery into new territories, suggesting the community was settled or named around that era of American history. Like much of Mason County, the area's early economy was driven by the logging boom of the late 1800s, when Michigan's vast forests of white pine were harvested and shipped across the Great Lakes. After the timber era wound down, the region transitioned to agriculture and small-scale farming, which have remained central to the community's identity ever since.
