Why Did Lord Baltimore Found Maryland?
Cecilius Calvert, the second Lord Baltimore, founded Maryland in 1634 as a proprietary colony to provide a refuge for English Catholics facing persecution at home. He obtained a charter from King Charles I granting him the territory north of the Potomac River and south of the 40th parallel. The colony's founding charter, issued June 20, 1632, specifically named it "Maryland" in honor of Queen Henrietta Maria, the king's Catholic wife. Though Calvert never set foot in the colony himself, he established it as both a business venture and a deliberate religious sanctuary, setting it apart from Virginia and other colonies founded primarily for commercial gain.
The religious dimension was not incidental. England's Catholic population had endured decades of legal restrictions, fines, and social exclusion following the Protestant Reformation. Calvert, himself Catholic, saw Maryland as a place where Catholics could own land, worship openly, and build a functioning society without the disabilities they faced in England. His vision included, from the outset, granting religious toleration to Christians of all denominations. The Toleration Act of 1649, passed by the Maryland General Assembly, codified this principle into law, becoming one of North America's earliest explicit protections for religious freedom. This act predated similar guarantees in other colonies by decades and reflected Calvert's original intent.
Economically, the venture followed the proprietary colony model common in the 17th century. Rather than direct settlement by the Crown, the king granted a charter to a nobleman (in this case, Calvert's father, the first Lord Baltimore) who could govern, lease land, and profit from the colony while the Crown retained ultimate sovereignty. Cecilius inherited the charter in 1632 and moved quickly to recruit settlers. The first colonists arrived in 1634 aboard two vessels, the Ark and the Dove, landing at St. Clement's Island on the Potomac River. The group included both Catholics and Protestants, reflecting Calvert's stated commitment to pluralism.
The location itself held strategic value. Maryland occupied a crucial mid-Atlantic position between Virginia to the south and Pennsylvania (settled later, in 1681) to the north. The Chesapeake Bay provided excellent natural harbors and access to inland waterways, making the colony economically viable from its early years. Unlike New England colonies, which struggled with poor soil and harsh climate, Maryland's Atlantic coastal plain and tidewater regions supported tobacco cultivation, the commodity that would drive economic growth and colonial survival. By 1700, Maryland's planter class had grown wealthy on tobacco exports to England.
Calvert's choice to establish a proprietary colony rather than seek direct Crown administration gave him unusual autonomy. He appointed governors, granted land, collected quit-rents (annual fees paid by landholders), and controlled patronage. This structure enriched the Calvert family for generations but also created tensions with settlers who eventually demanded more representative governance. By the early 18th century, Maryland had developed an elected House of Delegates that rivaled the proprietor's power, a friction that would persist until American independence.
The founding also carried geopolitical implications. England sought to establish firm territorial claims in North America against European rivals, particularly the Dutch and French. Maryland's establishment secured English control of the Chesapeake region and the lucrative fur trade flowing down the Potomac. The colony's borders were contested until 1767, when English astronomers Charles Mason and Jeremiah Dixon surveyed the boundary between Maryland and Pennsylvania, creating the Mason-Dixon Line. That survey line, still visible in some places, would later acquire symbolic weight as the informal boundary between North and South.
Religious toleration, though genuinely Calvert's policy, faced practical limits. Toleration extended to Christian denominations but not to Catholics and Protestants equally under all circumstances. Catholics faced property restrictions and political disabilities that lingered until American independence. Still, Maryland remained notably more accepting of Catholics than the other thirteen colonies. By the eve of the Revolution, Maryland's Catholic population had established itself as landowners, merchants, and civic participants. The Carroll family, one of Maryland's leading Catholic planter families, would later produce signers of the Declaration of Independence.
Visitors to Baltimore and Annapolis today encounter direct remnants of this founding legacy. St. Clement's Island, where the first settlers landed, remains accessible (though only by water) and is maintained as a historical site by St. Mary's County. The Maryland State Archives in Annapolis holds copies of the original 1632 charter. The Toleration Act of 1649 is displayed in the State House in Annapolis, itself a building begun in 1772 on the site where colonial government once convened. These sites and documents preserve the tangible record of Calvert's experiment in religious diversity and proprietary settlement.
Related Questions
Did Maryland remain a proprietary colony until independence? Yes. The Calvert family retained proprietary control until the American Revolution. After independence, Maryland became a state, and the proprietorship ended, though the Calvert name remained prominent in Maryland history and naming conventions.
Why is the Mason-Dixon Line called that, and what did it originally mark? Charles Mason and Jeremiah Dixon surveyed it from 1763 to 1767 to settle the long-standing border dispute between Maryland and Pennsylvania. It later acquired symbolic meaning as a cultural and eventually political boundary between North and South, though that association came long after its original survey.
