The Chesapeake Colonies were the Colony and Dominion of Virginia, later the Commonwealth of Virginia, and Province of Maryland, later Maryland, both colonies located in British America and centered on the Chesapeake Bay. Settlements of the Chesapeake region grew slowly due to diseases such as malaria. Most of these settlers were male immigrants from England who died soon after their arrival. Due to the majority of men, eligible women did not remain single for long. The native-born population eventually became immune to the Chesapeake diseases and these colonies were able to continue through all the hardships.
Chesapeake had a one-crop economy, based on tobacco. This contributed to the demand for slave labor in the Southern colonies. The tobacco also ruined the soil and new land was continually needed. White indentured servants were also common in this region early in its settlement, gradually being replaced by African slaves by the latter half of the seventeenth century due to improved economic conditions in Europe and the resulting decrease in emigration to the Chesapeake region. Indentured servants were people who signed a contract of indenture requiring them to work for their Chesapeake masters for an average of five to seven years, in return for the cost of the Atlantic crossing. When finished, he would be given land and an "outfit" consisting of a suit of clothes, some farm tools, seed, and perhaps a gun.
