The Ellis W. Hawley Prize is given annually by the Organization of American Historians to the author of the best book-length historical study of the political economy, politics, or institutions of the United States, in its domestic or international affairs, from the Civil War to the present. Eligible works are book-length historical studies written in English. Each entry must be published during the period January 1, 2024, through December 31, 2024. One copy of each entry, clearly labeled "2025 Ellis W. Hawley Prize Entry," must be mailed or emailed directly to the committee members. If a book carries a copyright date that is different from the publication date, but the actual publication date falls during the correct time frame making it eligible, please include a letter of explanation from the publisher with each copy of the book sent to the committee members. Please mail submissions to Megan Asaka, University of California; Sergio Gonzalez, Marquette University; Sarah McNamara, Texas A&M University, Department of History; Fawn-Amber Montoya, James Madison University; and E. Vines, California State University. Megan Asaka and E. Vines prefers digital submission through email.
