Explanation:

Initially, the United States was populated by migrants from the British Isles, especially England, Scotland and, to a lesser extent, Ireland. These were migrants who came to America in search of greater civil and religious freedoms, since in the British monarchy of the time, religion was a cause of social and political conflicts that limited the well-being of a large percentage of the society of the time. Thus, for example, the Puritans, the Quakers and many other people outside the Anglican Church began to arrive in the colonies, giving the colonies a British predominance over other ethnic groups.

Now, with the passage of time, new migratory waves began to arrive in America. Thus, Italians, French, Germans, Slavs, Russians, etc., began to be part of American society and to bring with them their own culture, religion and social values. These differed greatly from traditional British values (especially in religion), with which from the social and political establishment of the early twentieth century began to try to define and differentiate the "Anglo-Saxon race" over other immigrants European, valuing with greater emphasis the British cultural components than those of the other European countries.
