This discussion-based seminar will examine political, social, economic, and cultural factors that led to the collapse of a republican political system in Rome in the middle of the first century BCE. We will study the period from 146 BCE (the destruction of Carthage) to the assassination of Julius Caesar (44 BCE), which is the best documented time in all of antiquity, in light of primary sources of various kinds. This course will also consider why this historical era remained so fascinating for later generations, notably the American Founders. Students will be able to choose a topic to research for their oral report and final paper.
