History of slavery in Maryland

Slavery in Maryland lasted over 200 years, from its beginnings in 1642 when the first Africans were brought as slaves to St. Mary's City, to its end after the Civil War. While Maryland developed similarly to neighboring Virginia, slavery declined in Maryland as an institution earlier, and it had the largest free black population by 1860 of any state. The early settlements and population centers of the province tended to cluster around the rivers and other waterways that empty into the Chesapeake Bay^{[citation needed]}. Maryland planters cultivated tobacco as the chief commodity crop, as the market for cash crops was strong in Europe^{[citation needed]}. Tobacco was labor-intensive in both cultivation and processing, and planters struggled to manage workers as tobacco prices declined in the late 17th century, even as farms became larger and more efficient^{[citation needed]}. At first, indentured servants from England supplied much of the necessary labor but, as England's economy improved, fewer came to the colonies^{[citation needed]}. Maryland colonists turned to importing indentured and enslaved Africans to satisfy the labor demand^{[citation needed]}.

By the 18th century, Maryland had developed into a plantation colony and slave society, requiring extensive numbers of field hands for the labor-intensive commodity crop of tobacco^{[citation needed]}. In 1700, the province had a population of about 25,000, and by 1750 that number had grown more than five times to 130,000^{[citation needed]}. By 1755, about 40 percent of Maryland's population was black enslaved people, with African Americans slaves concentrated in the Tidewater counties where tobacco was grown.^[1] Planters relied on the extensive system of rivers to transport their produce from inland plantations to the Atlantic coast for export. Baltimore was the second-most important port in the eighteenth-century South, after Charleston, South Carolina.

In the first two decades after the Revolutionary War, some slaveholders freed their slaves. In addition, numerous free families of color had started during the colonial era with mixed-race children born free as a result of unions between white women and African-descended men.^[2] Although the colonial and state legislatures passed restrictions against manumissions and free people of color, by the time of the Civil War, slightly more than 49% of the black people (including people of color) in Maryland were free and the total of slaves had steadily declined since 1810.^[3]

During the American Civil War, which was fought over the issue of slavery, Maryland remained in the Union, though a minority of its citizens – and virtually all of its slaveholders – were sympathetic toward the rebel Confederate States. As a Union border state, Maryland was not included in President Lincoln's 1863 Emancipation Proclamation, which declared all slaves in states in rebellion to be free. The following year, Maryland held a constitutional convention. A new state constitution was passed on November 1, 1864, and Article 24 prohibited the practice of slavery. The right to vote was extended to non-white males in the Maryland Constitution of 1867, which remains in effect today. (The vote was extended to women of all races in 1920 by ratification of the Nineteenth Amendment to the United States Constitution.)
