In the first half of the nineteenth century, the population of the United States grew rapidly. The growth was due to emigrants from Europe. In the United States itself, the population also did not stand still and with each dec-ade moved the American frontier further to the West. The Americans easily took off and moved to other states and territories. However, in the South of the United States, migration had its own peculiarity: southerners pre-ferred to choose southern slave states for moving. At the same time, immigrants from Europe and migrants from the northern states did not often choose the South to start a new life. Most often they settled in New Eng-land or went to the West. This feature of migration in America influenced the formation of the southern type of Americans no less than slavery and the patriarchal way of life. Southerners were constantly in the same for-mation, and even when they moved to another state, they did not leave the world of slave-owners- planters. Mi-gration influenced not only the formation of two types of Americans, but also contributed to the creation of a new nation – the southerners. This nation was not destined to arise, which gives rise to heated historical discus-sions about the applicability of the concept of "nation" to Americans, in general, and to southerners in particu-lar. Therefore, the purpose of this article is to determine the place of migration in the formation of the southern national identity. In conclusion, the reasons for internal migration in the South are revealed and it is concluded that the southerners who moved only to other southern states gradually created a unique cultural, economic and political community that had all the prerequisites for the formation of a nation.
