Despite the supposedly homogenizing effects of globalization, people continue to be joined together and divided asunder by the languages they speak, the religions they follow, and the ethnic identities to which they belong. Such cultural features all have specific geographies, tied to particular places. But while cultural-geographical terms such as “the Arabic world” and “the Islamic world” are used ubiquitously, many people remain uncertain where such “worlds” are and how they differ from each other.The purpose of this map-intensive course is to explore the locational dynamics of the world’s languages, religions, and ethnic groupings. We will examine every world region, seeking to understand how places vary from each other with regard to the cultural attributes of their inhabitants. The course will explore the historical forces that have generated cultural diversity, and will carefully examine the processes of contemporary transformation.
