tobacco cultivation
Explanation:
- At the moment when the colonists intended to leave Jamestown in the spring of 1610, new settlers with supplies of supplies arrived from England, intending to enrich themselves in Virginia.
- A new group of settlers arrived again under the patronage of King James I. This time, a stronger leadership was envisaged, led by a governor who ruled with a group of advisers and a martial law was introduced that imposed harsh penalties on those who disobeyed it.
- To make a profit for the Virginia company, settlers have ventured into numerous small industries, including glass making, woodworking, resin, tar, and mineral fertilizer production. However, until colonist John Rolfe (who later married Powhatan's daughter Pocahontas) introduced tobacco cultivation around 1613, a money-making plant, none of the colonists' attempts to establish a profitable business proved successful. Tobacco cultivation required large tracts of land and plenty of labor, and stimulated the rapid growth of the Virginia colony.
- The newcomers also settled in the territories occupied by the Powhatan Indians, and the number of servants who came to Virginia increased.
