History

[edit]
Map of the Surveyed Part of the Territory of Michigan by Orange Risdon, 1825, showing an earlier, larger incarnation of Sanilac County, most of which had not yet been surveyed.

Sanilac County was probably named for a Wyandot (Huron) chief named Sanilac.[4] (See List of Michigan county name etymologies). The county was formed on September 10, 1822, by the Michigan Territorial Legislature, partitioning parts of St. Clair County and unorganized territory administered by Oakland County. The original boundary of the county was reduced in 1840, when parts were partitioned off to create Huron and Tuscola counties. The county government was fully organized on December 31, 1849.[1] In the middle of the 19th century, the area now called Port Sanilac was called Bark Shanty. It was named for a lone shanty made of bark, which was used to make shingles from pine. The county seat of Sanilac is the city of Sandusky.[citation needed]

The county government operates the jail, maintains rural roads, operates the major local courts, records deeds, mortgages, and vital records, administers public health regulations, and participates with the state in the provision of social services. The county board of commissioners controls the budget and has limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.
