Baltimore County Maryland

A Historical Overview of Baltimore County, Maryland

Baltimore County, located in the central part of Maryland, surrounds but does not include Baltimore City. Established in the 17th century, the county has played a significant role in Maryland’s colonial development, the American Revolution, the Civil War, and the region’s economic expansion. Today, it remains one of the state’s most populous and economically diverse areas, with a mix of suburban, rural, and industrial communities.

Colonial Origins and Early Settlement (1600s–1700s)

Baltimore County was officially founded in 1659, making it one of Maryland’s earliest counties. It was named after Cecilius Calvert, the second Lord Baltimore, who was granted the Maryland colony by the British Crown.

During the colonial era, the county’s economy was driven by tobacco farming, trade, and shipping. The region’s proximity to the Chesapeake Bay allowed for easy transport of goods, and early settlers established plantations along rivers such as the Patapsco, Gunpowder, and Back Rivers.

The county was originally much larger, encompassing what are now Harford, Carroll, and parts of Cecil and Howard Counties. Over time, these areas were separated into their own jurisdictions.

The American Revolution and Early Growth

Baltimore County played an active role in the American Revolution (1775–1783). Towns such as Joppa, which had been a thriving port, declined as Baltimore Town (now Baltimore City) became the region’s dominant commercial center.

During the war, local militias were formed to resist British rule. Baltimore County residents supplied food, weapons, and manpower to the Continental Army. In 1777, the Maryland General Assembly met in Old Joppa before relocating to Annapolis permanently.

After the Revolution, Baltimore County remained an agricultural powerhouse while also benefiting from the growth of Baltimore City’s port and industry.

The War of 1812 and the Battle of North Point

One of Baltimore County’s most significant historical moments occurred during the War of 1812, when British forces attempted to capture Baltimore. On September 12, 1814, the Battle of North Point took place in what is now Dundalk.

American militia, commanded by General John Stricker, engaged British forces led by Major General Robert Ross, who was fatally wounded in the battle. Although the British forces eventually reached Baltimore, the delay allowed American troops to strengthen their defenses at Fort McHenry, leading to the famous defense of Baltimore that inspired "The Star-Spangled Banner."

Today, the battle is commemorated in North Point State Park and the annual Defenders' Day celebrations.

The Civil War and Baltimore County’s Divided Loyalties

During the Civil War (1861–1865), Baltimore County, like much of Maryland, was deeply divided. While Maryland remained in the Union, there were strong Confederate sympathies, particularly among rural landowners.

  • Union forces occupied key locations in Baltimore County to prevent Maryland from seceding.
  • Confederate sympathizers in the county supported Southern causes, and some joined the Confederate Army.
  • The Baltimore & Ohio (B&O) Railroad, which ran through the county, was a major strategic asset for the Union Army, transporting troops and supplies.

After the war, the county’s economy transitioned from slavery-dependent agriculture to industrial and commercial development, particularly with the growth of the B&O Railroad and manufacturing in communities like Sparrows Point.

Industrialization and Economic Expansion (Late 1800s–Early 1900s)

By the late 19th and early 20th centuries, Baltimore County experienced significant industrial and suburban growth.

  • The Steel Industry: The Bethlehem Steel Plant at Sparrows Point (founded in the 1880s) became one of the largest steel mills in the world, attracting thousands of workers and transforming Dundalk and Essex into thriving industrial communities.
  • Railroad Expansion: The Pennsylvania Railroad and Western Maryland Railway improved transportation, connecting rural areas to Baltimore City.
  • Suburban Development: As Baltimore City became more crowded, wealthy and middle-class families moved to suburban areas like Towson, Catonsville, and Pikesville.

During this period, Towson, which had been a small farming community, became the county seat in 1854, replacing the older town of Joppa.

World War II and Postwar Suburban Boom (1940s–1960s)

During World War II, Baltimore County played a crucial role in war production. The Bethlehem Steel Plant in Sparrows Point produced steel for warships, tanks, and planes, while other industries supported the war effort.

After the war, the county experienced a massive suburban expansion:

  • New housing developments emerged in Towson, Parkville, Perry Hall, Dundalk, and Essex to accommodate returning veterans and their families.
  • Educational institutions grew, with the expansion of Towson University (originally Towson State College).
  • Shopping centers and highways were built, including the Baltimore Beltway (I-695), Pulaski Highway (U.S. Route 40), and Interstate 83, which connected Baltimore County to surrounding areas.

Modern Baltimore County (1970s–Present)

By the late 20th and early 21st centuries, Baltimore County evolved into a diverse economic and cultural hub. Key developments included:

  • The decline of heavy industry: The closure of Bethlehem Steel in 2012 marked the end of an era for Sparrows Point, but the area has since been redeveloped into Tradepoint Atlantic, a major logistics and distribution center.
  • Healthcare and education: Institutions such as Johns Hopkins University’s Applied Physics Lab, Towson University, and UMBC (University of Maryland, Baltimore County) have become economic and research powerhouses.
  • Economic and demographic shifts: The county has seen growth in technology, government contracting, and healthcare industries, while also becoming more racially and ethnically diverse.
  • Preservation and tourism: Historical sites such as Hampton National Historic Site, Fort Howard, and Jerusalem Mill Village continue to attract visitors interested in the county’s rich history.

Conclusion

Baltimore County has played a vital role in Maryland’s history, from its colonial roots and Revolutionary War battles to its industrial and suburban transformation. Today, it remains one of the state’s most important economic and cultural centers, balancing historic preservation with modern development.
