England's southern colonies in North America developed a farm economy that could not survive without slave labor. Many slaves lived on large farms called plantations. These plantations produced important crops traded by the colony, crops such as cotton and tobacco
The people in the south had a lot of land to farm and needed more help. Slaves provided them cheap labor.
Explanation:
Slave trade in the southern colonies was very popular and was one of the biggest trades at the time. Slaves helped them on their land for little to almost no pay. The slaves signed contracts to work for the slave owners for years basically just for a home to live in.
The compromise divided the lands of the Louisiana Purchase into two parts. Slavery would be allowed south of latitude 36 degrees 30'. But north of that line, slavery would be forbidden, except in the new state of Missouri.
