Answer:
Ships
Step-by-step explanation:
Slaves were brought from Africa, captured by the slave trader and transported them to colonies by ships. Africans were forced to board a ship and put in shackles. In the colonies, captured slaves were shipped to docks, later sold on auction. For the first time in 1619, Africans brought to the English colony of Jamestown. From there the slavery started in colonies because without them, the colonists could not survive.
