/kloc-what was the main flow direction of international population migration before the 0/9th century?

Here we mainly talk about16-1population migration before the 9th century. /kloc-after the great geographical discovery at the end of 0/5, the climax of population migration was set off. A large number of immigrants emigrated from Europe to the United States. At first there were Spanish and Portuguese, then there were French, Dutch and British. Only in the second half of the 1 8th century, nearly110,000 people moved out of Europe. This group of people mainly formed several human geography phenomena: 1. The birth of the American nation; 2. The formation of "Latin America". This event has made Latin English, Spanish, Portuguese (and French in Quebec, Canada) the common languages. White people have become the main race in the American continent. Argentina, for example, is 97% white, which is the country with the highest proportion of white people in Latin America. In addition, the colonists also transported millions of black people from Africa to America through evil "triangle sweaters", which greatly reduced the absolute population of Africa in the 1 8th century, reducing the number of people by nearly1100 million. Today, the southern United States and the West Indies have become one of the main distribution areas of blacks. Haiti and Dominica have become black countries.
