Michigan Counties 

In 1796, the acting governor of the territory officially set the boundaries for Wayne County, which, at that time, included all of what later became the state of Michigan and parts of Ohio, Indiana, Illinois and Wisconsin. By 1830, Michigan had 12 organized counties. By 1852, most of the Lower Peninsula counties were established. In 1891, the last of Michigan’s current 83 counties was organized.
