The early European economy was very good. It is one of the best countries in the world. It was only in the15th century that many countries here began to sail at sea. It can not only sail at sea, but also carry out two industrial revolutions. It is precisely because these activities in Europe not only promoted the economic development of Europe at that time, but also had an impact on the whole world, because Europe was very influential at that time, but those countries with good technology mastered these things. Instead of using them to help others, they began to bully those countries in trouble and then regarded them as their own countries. They will kill some local people on a large scale. In this massacre, Indians and African blacks should be the most seriously injured in Europe.
After hurting people in these places, they did not stop. In the later period, some European rulers still wanted to hurt some parts of Asia, and some parts of Asia became Europe at that time. Colonies, and the speed of becoming colonies is very, very fast, does not mean that they are slowly becoming. This is because many Asian countries are not very strong, and then they can't stop those countries in Europe. It was common at that time to trade people as commodities, especially those Europeans who bought and sold slaves. These people don't respect these slaves at all, and they don't treat them as human beings at all. Despising these people, such a book appeared at that time, which was very unfriendly to blacks and was a derogatory description.
Europeans want to say that blacks are bad people by covering up one of their crimes. In this case, the treatment of blacks is getting worse and worse. Later, white people completely stopped treating black people as human beings. They are just a commodity, just to help them get more money. Then they abandoned the black business. Although we later learned that there was a Renaissance in Europe, many people's ideas changed after the Renaissance, but a large number of people still have old ideas.
