I revised the map several times. In the beginning, I thought I could only draw a simple “tree”. But during the process, when an item is listed and adjusted. I find there are many possible angles to see the same items. Take the alternative view on the map as an example, if we consider things from the government’s side, the government imposes salt taxes (or duties) and starts wars. And if we compare the “duty” and “tax”, the duty causes wars while the tax causes revolutions. They are external and internal perspectives respectively. This also reflects “system thinkings”. Besides, The salt tax also supports some wars in history. Which makes things more interesting.
Another map:
The inclusion of “revolution” struck me – in your second map it is given prominence. I am curious what sort of revolution? Can you be more specific? Along those lines (thinking of power structures), where does capitalism fit into this?
In general, the next step is to go to the granular and specific – Which countries? What wars? etc.
