18th Century
Like its larger neighbor, Virginia, Maryland developed into a plantation colony by the 18th century. In 1700 there were about 25,000 people and by 1750 that had grown more than 5 times to 130,000. By 1755, about 40% of Maryland's population was black. Maryland planters also made extensive use of indentured servants and penal labor. An extensive system of rivers facilitated the movement of 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 latter colonial period, the southern and eastern portions of the Province continued in their tobacco economy, but as the American Revolution approached, northern and central Maryland increasingly became centers of wheat production. This helped drive the expansion of interior farming towns like Frederick and Maryland's major port city of Baltimore.
Maryland lost some of its original territory to Pennsylvania in the 1760s when, after Charles II granted Pennsylvania a tract that overlapped the Maryland grant, the Mason-Dixon Line was drawn to resolve the boundary dispute between the two colonies.
