Geography and landscape

The county occupies part of the glaciated prairie region of the northern Great Plains. Its landscape is dominated by agricultural fields, rolling grasslands and small wetlands used for crop production and livestock. Streams and seasonal lakes dot the area, and the county's transportation network connects communities by state highways and rail lines that support both local travel and goods movement.

History and name

Settlement and local government developed in the late 19th century with patterns typical of Dakota Territory counties. Brown County is named for Alfred Brown of Hutchinson County, who served as a Dakota Territory legislator in 1879. Local histories record the county's growth around farming, rail access and the establishment of Aberdeen as a regional hub (name origin).
