How have ethnopolitical landscapes transformed across Africa? The authors of this article analyze how ethnic identities have been influenced by two major socioeconomic revolutions of 19th and 20th century sub-Saharan Africa: cash crops and print technologies. They found that ethnic identities, through the means of politicization and boundary-making, had become more salient and politically relevant in communities where cash crops and print technologies were present. Furthermore, areas with cash crops and subsequent agricultural zones were found to have stricter ethnic boundaries and less interethnic marriage than areas with more print publications.
