Hillsdale County is a county located in the U.S. state of Michigan. As of the 2020 Census, the population was 45,746. The county seat is Hillsdale.

The Hillsdale County Courthouse was designed by Claire Allen, a prominent southern Michigan architect.

## History

The county is named for its rolling terrain. It was described by action of the Michigan Territorial legislature in 1829, and was organized six years later. See List of Michigan county name etymologies.
Hillsdale County was a New England settlement; its early settlers came from the northern coastal colonies – "Yankees", descended from the English Puritans who emigrated from the Old World in the 1600s. There was a wave of such settlers into the Northwest Territory during the early 1800s, many traveling on the newly completed Erie Canal, and made safe by the conclusion of the Black Hawk War. They brought with them a passion for education, establishing many schools. Many were abolitionists.

The county government operates the county 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.

### Republican Party Split

On August 12, 2022, the Hillsdale County Republican Party refused to let duly elected precinct delegates enter the County Convention. This was under the claim that Hillsdale County Clerk, Marney Kast, had deliberately spoiled certain candidates' ballots past the filing deadline. They held the convention with those who were not disavowed inside the Sozo Church. The duly elected precinct delegates held their own convention outside in the parking lot. The party split, and multiple lawsuits followed after.
Currently, the Michigan Republican Party recognizes Brent Leininger as the Chair of the Hillsdale County Republican Party, who was one of the precinct delegates previously disavowed.
