How and why did the relationship between slavery and race in British North America change between 1650 and 1750?

Between 1650 and 1750, the relationship between slavery and race in British North America evolved significantly as racial distinctions became more pronounced in the legal and social systems. Initially, many indentured servants, regardless of race, worked alongside enslaved Africans, but as the demand for labor grew, laws increasingly codified racial differences, privileging white servants and establishing lifelong slavery for Africans. By the mid-18th century, this led to a racialized system of chattel slavery, where Black individuals were seen as property, fundamentally altering societal perceptions of race and establishing a legacy of racial inequality that would persist in American society.
