The Boston Brahmins or Boston elite are members of Boston's traditional upper class. They are often associated with Harvard University; Anglicanism; upper-class clubs such as the Somerset in Boston, the Knickerbocker in New York City, the Metropolitan in Washington, D.C., and the Pacific-Union Club in San Francisco; and traditional Anglo-American customs and clothing. Descendants of the earliest English colonists are typically considered to be the most representative of the Boston Brahmins. They are considered White Anglo-Saxon Protestants.
The doctor and writer Oliver Wendell Holmes, Sr. coined the term "Brahmin Caste of New England" in an 1860 story in The Atlantic Monthly. The term Brahmin refers to the highest-ranking caste of people in the traditional Hindu caste system in India. By extension, it was applied in the United States to the old wealthy New England families of British Protestant origin that became influential in the development of American institutions and culture. The influence of the old gentry has been reduced in modern times, but some vestiges remain, primarily in the institutions and the ideals that they championed in their heyday.
And this is good old Boston, The home of the bean and the cod, Where the Lowells talk only to Cabots, And the Cabots talk only to God.
