As Makhno’s forces began to spread across Europe, regions with strong socialist influences began to join with the Free Soviets. This map demonstrates the regions under UFS control by the mid-1930s.
After downloading the original map and loading it into GIMP, I took the Fuzzy select took and selected all areas that were originally part of the Russian Empire, Bavaria, and the Anarchist Regions of Spain, and deleted it. Placing a transparent layer under it, I placed the Black Flag of Makhno’s Army under it.
After doing that, all the cleared areas not covered by the flag were filled with Black, and the image was exported as a PNG.
