Macomb County was organized as the 3rd one to be established in the Michigan Territory in 1818. It was named for Alexander Macomb, a highly-decorated general who served in the War of 1812. Arriving in the 17th century, the area's first settlers included French fur trappers and Moravian missionaries. The county seat, Mount Clemens Village, was platted in 1818.
