从15世纪末到16世纪初,随着地理大发现与新航线的开辟,世界资本主义的发展和殖民主义的扩张,欧洲殖民者为弥补劳动力的缺乏,来到已被他们征服的非洲,以抢夺、廉价交换或其他方式(如欧洲奴隶贩子们携带一些工业品或工艺品,同非洲的当地酋长交换奴隶,有时一两个玻璃珠就可换到一个奴隶),将奴隶运往美洲,出售给种植园和矿山,再从当地购买金银和各种土特产品带回欧洲出售,获取暴利。这就是历史上臭名昭著的“奴隶三角贸易”,如图所示。 From the end of the 15th century to the beginning of the 16th century, with the discovery of large geographical areas and the opening of new routes, the development of world capitalism and the expansion of colonialism, European colonists came to Africa, which they had conquered, to make up for the lack of labor. , cheap exchange or other methods (such as European slave traders carrying some industrial goods or handicrafts, exchanging slaves with local chiefs in Africa, sometimes one or two glass beads can be exchanged for a slave), and sending slaves to the Americas for sale to the plantations. And mines, and then from the local purchase of gold and silver and a variety of native products brought back to Europe to sell, get huge profits. This is the notorious “slave trade” in history, as shown in the picture.
