Historians draw many of their theoretical frameworks from the social sciences, including sociology, economics, and political science, and from literary and gender studies. This module investigates the role of theory in historical inquiry, both in framing research questions and in informing historians’ approaches to primary sources. It explores some of the major theoretical influences on historical research in recent decades, including Marxism, feminism, and postmodernism, and encourages students to reflect upon the theoretical and conceptual foundations of current research relating to their potential dissertation topics.
