Interminority racism is prejudice or discrimination between social subordinate groups. It is controversial to call it racism because of theories of power in society. However, prejudiced thinking does occur between minority groups. There are examples on public and personal levels. This article strictly addresses interminority racism as it exists in the United States of America, even though it happens in many other countries.

By the last quarter of the 18th century, US' colonies were dominated by an English majority. The language, customs, and ideas of government were shaped by Anglo Americans. In this way, the standards of American life were set: to be politically recognized as American, one had to conform to the Anglo American model.

There were ethnicities in the USA other than English. European minorities included the Dutch, Swedish, Norwegian, Scottish-Irish, and German. Also living in the United States were Native Americans and Blacks. The Anglo American majority needed a kind of rubric in order to decide who could be granted citizenship and for whom it would be denied. The law of 1790 stated that only free white immigrants could become naturalized citizens.
