Union League

The largest and best known of these clubs formed in Philadelphia, New York, and Boston, were composed of prosperous men who raised money for war-related service organizations such as the United States Sanitary Commission, which provided medical care to treat Federal soldiers wounded in battle at a time when the military was ill-prepared for the scale of need.

For instance, they helped to found the Metropolitan Museum of Art,[7] and funded construction of the Statue of Liberty's pedestal[8] and Grant's Tomb.
