The professionalization of the study of history in the second half of the nineteenth
century, including history's transformation from a literary genre to a scientific discipline, had important consequences not only for historians' perceptions of women but also for women as historians. The disappearance of women as objects of historical studies during this period has elements of irony to it. On the one hand, in writing about women, earlier
historians had relied not on firsthand sources but rather on secondary sources; the shift to
more rigorous research methods required that secondary sources be disregarded. On the
other hand, the development of archival research and the critical editing of collections of documents began to reveal significant new historical evidence concerning women, yet this evidence was perceived as substantially irrelevant: historians saw political history as the general framework for historical writing. Because women were seen as belonging to the private rather than to the public sphere, the discovery of documents about them, or by
them, did not, by itself, produce history acknowledging the contributions of women. In addition, genres such as biography and memoir, those forms of "particular history" that women had traditionally authored, fell into disrepute. The dividing line between"particular history" and general history was redefined in stronger terms, widening the gulf between
amateur and professional practices of historical research.
