Geography

Washtenaw County encompasses approximately 722 square miles, bordered by Livingston County to the north, Oakland County to the northeast, Wayne County to the east, Monroe County to the southeast, Jackson County to the west, and Lenawee County to the southwest. The Huron River flows from west to east through the county, providing a central geographic feature and recreational corridor. Major water bodies include Ford Lake and Belleville Lake, both impoundments of the Huron River, while the Waterloo State Recreation Area lies near its northwestern border. The terrain transitions from rolling hills and fertile agricultural land in the west to more developed areas around Ypsilanti and Ann Arbor in the east.

History

The region was originally inhabited by the Potawatomi and other peoples of the Council of Three Fires. The name "Washtenaw" is derived from the Ojibwe term *Wash-ten-ong*, meaning "far away country." European-American settlement accelerated after the Treaty of Detroit (1807) and the 1825 Treaty of St. Joseph, which ceded Native American lands. Washtenaw County was officially organized by the Michigan Territorial Council in 1826, with Ann Arbor designated as the county seat. The arrival of the University of Michigan from Detroit in 1837 transformed the area into an educational center. The county's growth was further spurred by the Michigan Central Railroad and industries like the Ypsilanti automotive factories, including the famous Willow Run bomber plant during World War II.
