The term "Anglo-Saxon" is sometimes used to refer to peoples descended or associated in some way with the English ethnic group, but there is no universal definition for the term. In contemporary Anglophone cultures outside Britain, "Anglo-Saxon" may be contrasted with "Celtic" as a socioeconomic identifier, invoking or reinforcing historical prejudices against non-English British immigrants, such as the Irish. "White Anglo-Saxon Protestant" (WASP) is a term especially popular in the United States that refers chiefly to long-established wealthy families with mostly English ancestors. As such, WASP is not a historical label or a precise ethnological term but rather a reference to contemporary family-based political, financial and cultural power e.g., The Boston Brahmin.
