This prize acknowledges the generations of women whose opportunities were constrained by the historical circumstances in which they lived. The Mary Nickliss Prize is given annually to an academic historian for "the most original" book in United States Women's and/or Gender History (including North America and the Caribbean prior to 1776). The OAH defines "the most original" book as one that is a path breaking work or challenges and/or changes widely accepted scholarly interpretations in the field. If no book submitted for the prize meets this criterion, the award shall be given for "the best" book in U.S. women's and/or gender history. "The best" book recognizes the ideas and originality of the significant historical scholarship being done by historians of U.S. Women's and/or Gender History and makes a significant contribution to the understanding of U.S. Women's and/or Gender History. Each entry must be published during the calendar year preceding that in which the award is given (January 1, 2022 through December 31, 2022). Please visit the scholarship's website for more information.
