Isabella County is located in the state of Michigan. As of the 2020 Census, the population was 64,394. Its county seat is Mount Pleasant. The area was known as Ojibiway Besse, meaning "the place of the Objibwe". Isabella County contains the Isabella Indian Reservation, on which members of the Saginaw Chippewa Tribal Nation live.
The Michigan Territory was admitted to the Union as Michigan state in early 1837. By 1859, Isabella had sufficient settlement and interest in self-government that the state legislature authorized its organization. Based on a suggestion by Henry Rowe Schoolcraft, the U.S. Indian agent in this area, the county was named after Queen Isabella I of Castile, who with her husband Ferdinand commissioned Columbus's expedition to the New World.
