The Jamestown settlers used the help of slavery and fertile soil to grow tobacco, a cash crop that John Rolfe had brought, and export it to England for profit.
A lot of Jamestown's colony of men, was killed by Powhatan and Patowomeck Indians.
The colony established a House of Burgesses in 1619 as form of representative government. It was for the use of immediate decisions when the king was too far away to properly give orders.
Jamestown, Virginia was on a swampy peninsula, made easy to defend, with fertile soil. The drinking water was brackish, and the settlement suffered from disease-carrying mosquitos.
It is surprising that Jamestown was a success because they had to deal with starvation, disease, Indians, they had to create their own representative government, and almost all of the settlers were men that were not used to working. Most people would look at Jamestown and give up all hope. Until John Ralph came along, with tobacco in his pocket. The fertile soil was perfect for the cash crop to thrive in. Ever since then, Jamestown has been a successful colony.
