First settled in the 17th century when the area was part of Anne Arundel County, early towns formed around grist mills. Nearby quarries and mills shaped Ellicott City before the more well-known impact of the B&O Railroad in the 1830s. Cotton mills flourished, and mill towns like Savage grew. In the 20th century Savage briefly became the Christmas capital of the country. It was also a well-known sundown town. Historically Black communities dealt with battles over education as the state emerged from segregation. Development brought suburban neighborhoods and change to rural areas, and planned communities like Columbia affected Guilford and other surrounding towns. Local authors Nathan Davis and Wayne Davis explore local myths and uncover erased histories.
