Hay, David

David's main interests focus on the history of warfare, violence and of women and gender in the Middle Ages, particularly the military career of Countess Matilda of Canossa (1046-1115) and contemporary reactions to a woman's leadership in war. Other areas of interest include medieval military theory and theology, the Crusades, Canon Law, social violence and masculinity.
