A map I've created showing Europe in 1925 after the various treaties have been implemented following World War One. I've included the occupied Rhineland and the Ruhr region as one piece, even though by 1925, both had pretty much been cleared of foreign troops (Thanks to the 1924 Dawes Plan & 1925 Locarno Treaties). Also, the Saar district is shown and it would remain occupied until the 1935 plebiscite. The Free City of Danzig is also shown. By 1925, the Memel Territory (southern Lithuania/northern East Prussia) had been annexed by Lithuania.
I have used original treaties and 1919-1925 maps as much as possible to draw these borders. I believe I still have all the original primary sources if one is so inclined to see them.
This is a work in progress. I intend to place country names on the map. Additionally, this is a Google Earth file. Each country is a separate file with hundreds, if not thousands of separate polygons. I am also creating "country files" for each country showing the proper name, flag, heads of state/government, a short narrative on the borders, and a short historical narrative about the country in 1925 or the 1920s, as well as, one or two websites where one can go for more information. Inside the narratives I have hyperlinked to treaties or wikipedia articles as I can.
This is the first in what I hope are many maps that I want to use in the classroom. I will upload all the Google Earth files when I am completed with the entire project.
