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: -Slavery was so profitable, it sprouted more millionaires per capita in the Mississippi River valley than anywhere in the nation. With cash crops of tobacco, cotton and sugar cane, America’s southern states became the economic engine of the burgeoning nation. Their fuel of choice? Human slavery.

Detailed explanation-3: -A slave plantation was an agricultural farm that used enslaved people for labour. The practice was abolished in most places during the 19th century.

Detailed explanation-4: -The estimates based on this new approach suggest that the increase in output per enslaved worker was responsible for roughly a fifth of the growth in commodity output per capita for the United States as a whole between 1839 and 1859-between 18.7 percent and 24.3 percent.
