Cultural Geography, Genetics, Historical Geography, Linguistic Geography, North America, Russia, Ukraine, and Caucasus, Siberia / By Martin W. Lewis

The GeoCurrents series on Siberia concludes by looking first to the future and then into the distant past: the preceding post examined the possible consequences of global warming on the region, while the present one turns to much earlier times, exploring the position of Siberia in human prehistory and especially its crucial role in the peopling of the Americas.

New Evidence on the Settlement of Madagascar

Art and Culture News, Genetics, Historical Geography, Islands, Migrations, News Map / By Martin W. Lewis

A new study of the genetic background of the people of Madagascar sheds light on the settlement of the island. It has long been known that the initial movement of people to Madagascar was relatively recent (1,000 to 1,500 years ago), and that it originated not from the African mainland but rather from the islands of what is now Indonesia. – Read More

Mapping Language and Race in the Finnic World

Cultural Geography, Genetics, Geographical Thought, Linguistic Geography, Russia, Ukraine, and Caucasus / By Martin W. Lewis

In skimming through old atlases, one might be surprised to find Finns racially classified as yellow-skinned Mongolians. Yet until fairly recently, that was the norm. Consider the 1962 map posted above, “Classification of Mankind By Color of Skin,” from the popular Bartholomew’s Advanced Atlas of Modern Geography. Here both Finns and Estonians – Read More

About GeoCurrents

GeoCurrents is dedicated to exploring the geographical and historical patterns that underlie the world’s current events and that structure global and regional relationships. Maps are used in all posts not merely to show where events occur, but also to illustrate the processes involved.

GeoCurrents tries to avoid taking sides on contentious issues, seeking rather to foster an enriching exchange of information and ideas. As its scope is both fully global and deeply historical, the author is usually operating outside of his own fields of expertise. As a result, mistakes and simplifications can be expected. Corrections and elaborations are more than welcome in the comments section. Comments with insulting or abusive language, however, will be deleted.

Readers interested in opinion-based essays by Martin W. Lewis will be able to find them on his personal webpage [currently under preparation].

About The Author

Martin W. Lewis is senior lecturer emeritus at Stanford University, where he taught world history and world geography from 2002 to 2022. He earned a PhD in geography from the University of California at Berkeley in 1988, and previously taught at George Washington University and Duke University. A list of his published works will soon be made available on his personal website [currently under preparation].

GeoCurrents’ Conceptual Concerns

GeoCurrents is concerned about almost anything that has a geographical expression and hence can be explored and elucidated through maps. Topics of interest range from the deadly serious to the quirky and whimsical.

Many GeoCurrents posts take on issues of political geography, ranging from wars and ethnic conflicts to electoral returns. Behind these writings is a conviction that the basic world political map is unduly simplistic, making the world seem much more orderly than it really is. A book-length elaboration of this thesis – entitled Seduced by the Map – will be available on the author’s personal webpage by the end of 2023, if not earlier. The introduction and initial chapters on this book can be found on this website. A summary of the main arguments in Seduced by the Map can be found here.
