Rolling Road was used to transport tobacco south from plantations to the Patapsco River on horse-drawn wagons.
In 1787, the Ellicott family built the Frederick Turnpike to transport goods from their flour mill, Ellicott Mills, to the Baltimore harbor. Charles Carroll, a signer of the Declaration of Independence, owned the land around the then newly built road. He instructed his son-in-law, Richard Caton, to develop the area along the road. Caton and his wife, Mary Carroll Caton, lived in Castle Thunder, constructed on the Frederick Turnpike in 1787.[7]
Caton gave his name to the community and called it "Catonville," although the name was changed to "Catonsville" in the 1830s. Businesses were built along the Frederick Turnpike for travelers traveling from Ellicott City to Baltimore. Catonsville served as a layover stop for travelers and the town increasingly grew and developed.[8] The pleasant surroundings attracted wealthy Baltimore merchants who built large Victorian and colonial summer homes to escape Baltimore's summer heat.[5]
Starting in 1862, horsecar services connected Catonsville to Baltimore. In 1884, the Catonsville Short Line railroad was built, providing 8 roundtrip trains to Baltimore daily. This allowed residents to commute to work in Baltimore. Commuter traffic exploded in the 1890s with the construction of electric streetcar lines and fancy housing developments. Catonsville had become one of the first commuter suburbs in the United States. Baltimore has tried to annex Catonsville, although their attempts have all been failures.[5][8] The last attempt was in 1918.
Homes of all sizes were constructed rapidly through the 1970s, when much of land around the Frederick Turnpike had been converted into housing. A new and modern business district opened along the newly built Baltimore National Pike, north from the Frederick Turnpike.
Catonsville was briefly made famous during the 1968 protest by the "Catonsville Nine", during which draft records were burned by Catholic anti-war activists.
In 2002, the Maryland legislature issued a proclamation declaring Catonsville to be "Music City, Maryland", because of the concentration of musical retail stores, venues and educational facilities in the area. Life Sounds Great is a series of compilation albums highlighting Catonsville musicians.
In 2007, Money magazine ranked Catonsville the 49th best place to live in the United States and the third best in Maryland and Virginia.
Catonsville lies above the Fall Line within the Piedmont Region of Maryland, a region characterized by broad, rolling hills punctuated by streams and rivers. Catonsville overlooks the coastal plain and Chesapeake Bay to the East. The Appalachian Mountains lie approximately 40 miles west of the town.
