The Agricultural History Society was founded in Washington, DC in 1919 "to promote the interest, study and research in the history of agriculture." Incorporated in 1924, the Society began publishing a journal, Agricultural History, in 1927. The term "agricultural history" has always been interpreted broadly, and the Society encourages research and publishes articles from all countries and in all periods of history. Initially affiliated with the American Historical Association, the Agricultural History Society is the third oldest, discipline-based professional organization in the United States. Currently the membership includes agricultural economists, anthropologists, economists, environmentalists, historians, historical geographers, rural sociologists, and a variety of independent scholars.
