The correct answer to this open question is the following.
We are talking about colonial times in North America, where white English people left Britain in order to pursue new goals and have better opportunities in the new continent.
The development of the southern colonies stemmed from the effort and perseverance of the people. The southern colonies were Maryland, Virginia, and Carolina, which years after divided in two: North and South Carolina. The location and place of these southern colonies were an important factor for their development. The good soil of the land and good climate conditions allowed farmers to grow great crops to the degree that southern colonies were known as the "breadbasket of America." They exported their crops to Europe, where there was a big demand for corn, Indigo, rice, and tobacco. This represented a big advantage for economic development.
Regarding the relations with Native American Indian tribes, at first, colonists tried to maintain a peaceful coexistence to try to live in harmony with them, but things complicated when more people arrived at these regions and tried to exploit more raw materials that were in the Indian territories.
