USA HISTORY

Detailed explanation-1: -The settlements required a large number of laborers to sustain them. Because these crops required large areas of land, the plantations grew in size, and in turn, more labor was required to work on the plantations. Plantation labor shifted away from indentured servitude and more toward slavery by the late 1600s.

Detailed explanation-2: -Throughout the 17th century, European settlers in North America turned to enslaved Africans as a cheaper, more plentiful labor source than indentured servants, who were mostly poor Europeans.

Detailed explanation-3: -As the demand for slaves increased with European colonial expansion in the New World, rising prices made the slave trade increasingly lucrative.

Detailed explanation-4: -European settlers brought a system of slavery with them to the western hemisphere in the 1500s. Unable to find cheap labor from other sources, white settlers increasingly turned to slaves imported from Africa. By the early 1700s in British North America, slavery meant African slavery.
