Thus, European society, already in the 17th-18th centuries, lost its former staticity (that is, immobility), literally starting to move. But in the 19th century, there is truly an explosion of social mobility. Its content also changes: mobility becomes less spontaneous, that is, it ceases to depend on many random circumstances. So, in the 17th century, many Protestants would probably have preferred to stay in their European homeland, if they did not suffer there, from religious persecution. And the blacks, who were exported from Africa in the holds of the ships, were not asked at all if they wanted to go to America unknown to them. The main stream of immigrants in the 19th – early 20th centuries, as before, was directed to the United States. From 1820 to the beginning of the First World War, that is, in 94 years, about 32 million people arrived in the United States (mainly from Europe). Among them were the British and French, Germans and Italians, by the end of the 19th century. the influx of immigrants from Southern and Eastern Europe, including from Russia, has noticeably increased. Quite a few Europeans also moved to the colonies – to Algeria and India, Canada and Australia, etc. And in southern Africa, the Boer republics arose with a significant white population. White colonists willingly moved there after the conquest of these republics by Great Britain.
