This research paper analyzes the effect that cartoonist Thomas Nast had on politics during his time, and the impact that his drawings had on the events that they depicted. It also argues that Nast was using his cartoons to try to influence his audience to take action and participate in politics. Nast’s cartoons were not only influential at the time, but some of them are still often seen today; our modern Santa Claus and the elephant that symbolizes the Republican Party are just a couple examples. Why were Nast’s cartoons so revolutionary? And what sets them apart from political cartoons of today? This paper will explore the answers to these questions.
