What was established in Virginia that resulted in the importation of indentured servants and African slaves to that colony?

plantations with cash crops

Explanation:

Virginia was a perfect place for planting cash crops. The Europeans saw its potential, as it had good climate, more than enough water, and fertile soil. Since there was big demand for the cash crops in Europe, the colonists started to create large plantations. Initially they wanted to use the Native Americans as labor force, but because of the spreading of diseases, most of them died out. This left the colonists with enormous plantations and no labor force to work on them. As the word spread out that there is slaves in abundance f=in Africa, the colonists started to buy African slaves to work on their plantations. Getting African slaves was beneficial to them in many ways; they only needed shelter and food; no wage was paid to them; the owners had all rights over them; they were good workers; the working hours were determined by the owners.
