Harper's Magazine made its debut in June 1850, the brainchild of the prominent New York book-publishing firm Harper & Brothers. Harper's Magazine, the oldest general-interest monthly in America, explores the issues that drive our national conversation, through long-form narrative journalism and essays, and such celebrated features as the iconic Harper's Index. With its emphasis on fine writing and original thought Harper's provides readers with a unique perspective on politics, society, the environment, and culture.
