German-Land: Language beyond Borders (1867)
Geographer and cartographer Heinrich Kiepert (1818–1899) was most famous for his historical topography of Asia Minor and the eastern Mediterranean. This color map from 1867 is titled “Map of Peoples and Languages of Germany and its Neighbors.” As ethnographic representations of the cultural nation [Kulturnation], maps of this sort enlisted the modern science of statistics to create and demarcate linguistic communities.
