The American Historical Association (AHA) is a nonprofit membership organization founded in 1884 and incorporated by Congress in 1889 for the promotion of historical studies. The AHA provides leadership for the profession, protects academic freedom, develops professional standards, aids in the pursuit and publication of scholarship, and supplies various services to sustain and enhance the work of its members. The association’s principal functions fall within four realms: publication, teaching, advocacy, and networking. As the largest historical society in the United States, the AHA serves historians representing every historical period and geographical area. The nearly 14,000 members include academics at universities, two- and four-year colleges, museums, historical organizations, libraries and archives, but also independent historians, students, K–12 teachers, government and business professionals, and countless people who, whatever their profession, possess an abiding interest in history.
