Calvin Coolidge is the only President in American history born on the Fourth of July. It is appropriate that he bears this distinction, since Coolidge—more so than any other President of the 20th century—embodied a dedication to the principles that the Founders fought to establish in the American Revolution. In addition, he lived at a time when these principles came under radical assault, and Coolidge, a fierce critic of Progressivism, offered one of the greatest defense of these principles. He is an intellectual and political forefather of modern American conservatism.
