The purpose of this thesis is to discuss the roles played by Irish Catholic women in the Irish Rebellion of 1641. The primary goal is to examine the factors that determined the nature of those roles. To achieve this end, I used the information contained in the 1641 depositions, a collection of sworn statements given by the victims of the rebellion. The depositions are valuable in two ways. First, eyewitness testimony contained therein is generally reliable, and can be used to construct an accurate narrative of the rebellion. Second, less reliable hearsay evidence is crucial to understanding the fears of English and Scottish Protestants and their perceptions of female rebels. I was aided by the earlier efforts of historians such as Nicholas Canny and Mary O'Dowd. In the course of this thesis, I intended to argue that the actions of Irish Catholic women in the rebellion were largely determined by their social status, geographic location, and prior relationships between female rebels and their allies and victims.
