It's curious how people are responding to the title, rather than the post, which touches on the title but is mostly about another thing: >> There’s something beguiling about the thought that a simple arrangement of lines might explain the world — like seeing human history as an enormous game of Civilization 6. But of course, that’s also the problem with using maps as a way of understanding history. If you’re not care…
The intentions don't just affect the way the data is presented, but can affect the underlying data itself. For example, the "German Claims in Africa" shows vast areas as "German claims" on what must be very shaky justification. The presentation is very clear, but the data is misleading.
F.ex. the "German Claims in Africa according to Professor Delbruck" map appears to originate in a British publication [0], in the context of a "German aims in Africa" section [1]...
>> [Beginning with] "It might be thought that even the rapacity of Prussia could hardly fail to be satisfied with such wholesale spoliation of territory such as this, but the foregoing [European territorial] terms by no means exhaust the demands which are to be made of the striken foe."
>> "The idea that at the end of the war Germany would make enormous acquisitions in Africa was just as popularly believed and lingered just as tenaciously in the Teuton mind as the delusions with regards to the European settlement. As late as the Summer of 1917 the well-known German historian, Professor Delbruck, gives the following interesting account of German's aims in this directions [... Prof Delbruck's quote...] [...] I have therefore reduced it to map form in order that a comparison may be made between these two pathetic tributes to the tenacity of German hopes (See Map 13)."
So the map that we're looking at is a British graphical depiction of something a German military historian said, provided in the context of demonstrating that German colonial claims in Africa are over-optimistic and -broad with regard to their military performance by the end of WWI.
And yet the intent behind the creation of that map is largely lost by viewers.
The blog post captions it as "Putative German claims in Africa amounted to nearly half the continent" which is more or less accurate, albeit leaving out the fact that the map is apparently a British creation.
The British component possibly affected the precise boundaries as drawn, as well as the decision to make British and German colors similar, so as to decrease the obviousness of British colonies and emphasize the monolithic nature of desired German African colonies.
