I was wondering how I would be able to find a Old Middle ages 13th Century – 16th Century map of Germany (or at least Europe). Or any shapefiles/layers during this time period which would show the changes in political boundaries? I am making a map of it in ArcGIS Desktop.
You might have to create them yourself. There doesn't seem to be a lot of historical data out there. Several years ago I made some shapefiles of US states over the decades, based on digitized paper maps in various atlases. They are not especially accurate or authoritative, but good enough for the types of maps I was making.
If anyone knows of good sources, though, I'd also be interested.
