"Since its inauguration [in 1921], Phi Alpha Theta has grown to more than eight hundred thirty-nine chapters in fifty states, more than any other accredited four-year college honor society. The total number of initiates since its inception is more than 281,000. As part of its commitment to acad
emic excellence, Phi Alpha Theta continues to participate actively, through its Executive Director and President, in the Association of College Honor Societies. Phi Alpha Theta enjoys the distinction of being one of three original departmental honor societies with membership in the ACHS. In 1996 Phi Alpha Theta received recognition as a non-profit 501(c)(3) organization. Contributions to our Society are now tax-deductible as allowed by law. We are a professional society whose mission is to promote the study of History through the encouragement of research, good teaching, publication and the exchange of learning and ideas among Historians. We seek to bring students, teachers and writers of History together for intellectual and social exchanges, which promote and assist Historical research and publication by our members in a variety of ways."
