As the oldest and largest professional organization dedicated to “the study and promotion of history and historical thinking,” the American Historical Association (AHA) has a lot on its plate. The Association was founded in 1884 when a group of academics recognized that a new discipline was taking shape. They subsequently split from the American Social Science Association, despite objections from their social scientist peers. Today, the AHA has over 15,000 members. The website is stocked with historical goodies. Click About AHA & Membership, and then AHA History and Archives, where you can read a Brief History of the AHA, AHA Annual Reports going back to 1997, and Presidential Addresses going back to the 1880’s. The AHA Today Blog, easily accessible from the homepage, is updated daily. Also, don’t miss the American Historical Review and Perspectives on History, listed under Publications and Directories.
