Students in History courses explore the past from many perspectives, whether political, economic, cultural or intellectual, religious or social. Through the course of their career at UB, students learn what happened, and why. They analyze historians' debates, and develop the skills with which to become historians themselves, critically analyzing primary sources, the building blocks of historical research, and writing their own historical arguments and texts. Students interpret a range of sources, including, but are not limited to, published or unpublished written texts; film, photography and other visual material; and oral testimony. The recent explosion of digitized materials has made a vast array of evidence available to undergraduates in their study of change over time in human society.
