The Editorial Board is pleased to present the second issue of the fifteenth volume of the Penn History Review, the Ivy League’s oldest undergraduate history journal. The Review continues to publish outstanding undergraduate papers based on original primary research. The Board is proud to feature scholarship that maintains our tradition of insightful and diverse historiography. These papers span not only centuries and geographic regions, but also across disciplines in the study of history. The authors published in this issue approach their historical inquiries with a particular respect to the larger theme of exploration. In addition to providing four exemplary student essays, this issue of the Review also offers a special section entitled ‘The Study of History.’
