Ideology - A system of beliefs that may include figures of speech, stereotypes, and social and cultural assumptions based upon the dominant culture's definitions of nature and social relationships. Ideological categories arise and subside as hierarchical power relationships change.

The core of the dominant ideology remains intact until a paradigm shift over several hundred years obscures what was once the dominant ideology.

Hence, examples are commonly found in ideological shifts with US presidencies and text book editions.
