1400 - 1600
Although forms of slavery existed before the 1400, the 1400s marked the start of European slave trading in Africa with the Portuguese transporting people from Africa to Portugal and using them as slaves. In 1562, the British joined in on the slave trade in Africa. The development of plantation colonies increased the volume of the slave trade. Later on throughout the 1600s, other countries became more involved in the European slave trade. These included Spain, North America, Holland, France, Sweden, and Denmark (Agatucci).
