The Organization of American Historians (OAH), formerly known as the Mississippi Valley Historical Association, is the largest professional society dedicated to the teaching and study of American history. OAH's members in the U.S. and abroad include college and university professors; historians, students; precollegiate teachers; archivists, museum curators, and other public historians; and a variety of scholars employed in government and the private sector. The OAH publishes the Journal of American History. Among its various programs, OAH conducts an annual conference each spring, and has a robust speaker bureau—the OAH Distinguished Lectureship Program.
