Long before European settlement, the peninsula that includes modern-day Lusby was inhabited by indigenous Algonquian-speaking peoples, particularly the Patuxent and Piscataway tribes, who thrived on the abundant seafood and fertile lands along the waterways.
During the colonial era of the 17th and 18th centuries, Southern Maryland was dominated by tobacco farming. Large plantations relied heavily on enslaved labor to cultivate the crop, which was shipped back to England from deep-water ports along the Patuxent River and Chesapeake Bay. The area remained highly agricultural and sparsely populated well into the 20th century.
Lusby's modern transformation began in the mid-20th century. In the late 1950s, developers purchased large tracts of farmland to create the Chesapeake Ranch Estates, envisioning a private waterfront resort community. Over the decades, this development evolved into a massive, year-round residential neighborhood.
The 1970s marked a monumental economic shift for Lusby with the construction of the Calvert Cliffs Nuclear Power Plant, Maryland's only commercial nuclear energy facility, which brought significant employment and infrastructure to the area. This was followed by the development of the Cove Point LNG terminal. Today, Lusby is a modern suburban community that maintains its connection to the prehistoric and colonial history of the Chesapeake region.
