At the beginning of the establishment of the British North American colony, there was an urgent need for a large number of laborers, so European colonists kidnapped and plundered blacks from Africa and became slaves in the New World. 16 19 The Dutch first transported 20 slaves to James, Virginia, and sold them to British colonists. At first, the number of blacks was small. By the middle of17th century, there were only 300 blacks, and their legal status was uncertain. /kloc-in the second half of the 0/7th century, various colonies successively promulgated laws to determine the slave status of blacks. Slavery inherited the barbaric tradition of ancient slavery. Black people are the tools of conversation and property of their owners. 1709, a large-scale slave auction market appeared on Wall Street in New York. On the eve of the North American War of Independence, the total number of black slaves was nearly 500,000, accounting for 1/7 of the population of each colony. There were slaves in British North America 13 colony, but they were mainly concentrated in southern plantations, producing cotton, tobacco, rice and indigo to meet the demand of the world market.

Black slaves kept resisting. Before the War of Independence, there were at least 50 recorded uprisings, and the black struggle dealt a heavy blow to American slavery. This is slavery.
