Carroll County while predominantly rural, it has become increasingly suburban in recent years. Prior to European colonization, the land that now makes up Carroll County was inhabited by Native Americans for thousands of years. Numerous Native American archaeological sites and archeological artifacts have been located across the county. Native Americans used the land for permanent settlements, and as hunting grounds. The earliest European settlers in Carroll County were predominantly Pennsylvania Dutch from southeast Pennsylvania and English from the Tidewater region of Maryland. German was the predominant language of Carroll County until the Civil War.
