Final answer:
Indentured servitude was initially used to meet the labor demands of colonial plantations, but due to harsh conditions and the lack of land for freed servants, the system gave way to racially based permanent slavery.
Step-by-step explanation:
The labor needs of colonial plantation owners for crops like tobacco, rice, and indigo resulted in the importation and use of indentured servants. These servants agreed to work for a set number of years in exchange for passage to America and a promise of land once their service ended.
As the need for labor grew and the best lands were taken by wealthy landowners, indentured servants who survived their term faced difficulties and often had to settle in less desirable western territories.
Over time, the system evolved into one relying more on enslaved African labor, which became inheritable and race-based, transforming the character of labor in the New World.
Indentured servants were initially an integral part of the labor force in the Americas to grow labor-intensive crops. However, due to the harsh conditions, high mortality rate, and eventual exhaustion of land availability, the system proved unsustainable.
Consequently, as demand for labor increased and after events like Bacon's Rebellion, slavery became more prevalent, permanently altering the labor system in the colonies.
