Founded in 1907, the Organization of American Historians (OAH) is the world’s largest professional association dedicated to American history scholarship. With more than 7,800 members from the U.S. and abroad, OAH promotes excellence in the scholarship, teaching, and presentation of American history, encouraging wide discussion of historical questions and equitable treatment of history practitioners. OAH publishes the quarterly Journal of American History, the leading scholarly publication and journal of record in the field of American history for more than nine decades. It also publishes The American Historian magazine. Each year, OAH hosts an annual meeting which is the nation's largest single gathering of American historians. It periodically hosts regional meetings as well. Formerly known as the Mississippi Valley Historical Association (MVHA), the association became the OAH in 1965 to reflect a broader scope focusing on national studies of American history. The OAH headquarters is located in the historic Raintree House on the Indiana University campus.
