Question

how did the slavery change and what factors were responsible for this change?

Answer 1

One significant way it changed was that the latter half of the 17th and first half of the 18th century saw the rise of large plantations, particularly in the deep South (Mississippi, Alabama and Georgia) whose economics were built around one or two cash crops (cotton being the biggest).
