This thesis examines the development of military culture in, and its effects on, early modern English society. Militarism during the late Elizabethan and early Stuart periods was not reinforced by military institutions directly interfering with the private lives of individuals, or by controlling the thoughts and actions of the whole nation. It was, however, strongly influenced by the culture of a military elite, represented by leading noblemen such as Leicester, Sidney, Essex, and Prince Henry, who paid considerable attention to the theatrical aspects of formal and ceremonial occasions and how their military role was portrayed in art and literature. Unlike the usual traditional portrayal of these prominent figures as incompetent military leaders who rushed blindly forwards in pursuit of military glory, we will see that through their aristocratic patronage of various art forms they promoted their image as competent Protestant warriors, and helped the public to be receptive to a variety of military ideas. The principal motivation of this study is to consider a multiplicity of perspectives on how a military culture was constructed, through a variety of genres, and how particular views on military matters were integrated into popular culture. Literary critics and historians have previously examined certain aspects of militarism in this period but this study aims to take a holistic view of how the military culture developed and affected the public sphere.
