The treatment of cultural difference and diversity by French-speaking cartoonists has changed radically over the last few decades, as four articles in this special issue demonstrate. What has not changed since the nineteenth century is the centrality of these themes to comics, which have been a globalizing medium in a shrinking world throughout the period. French-language comics are exemplary of these transformations, insofar as France was a major imperialist power during the nineteenth and twentieth centuries. Moreover, France has long been home to ethnic and religious minorities, and was a major center of immigration during the twentieth century. These socio-historical trends have left a huge imprint on comics within France itself, but the French also exported the form along with their language to most of their colonies, which has given rise to (post-)colonial traditions of cartooning in French-speaking regions across the globe.
