Can you name the subdivisions of Medieval Europe during the year 1000 AD (height of the middle ages)?
Check the caveats.
Also a side note: These countries aren't shown at their peak (when they owned the most territory), this map is only the territory they owned in the year 1000 AD.
If the country has further subdivisions (i.e. states/counties), then you will need to name those and not the country name (if this is the case, the country name will be labeled).
If the country has no further subdivisions, all you need to do is name the country (as this serves as the subdivision itself).
Other regions not part of Medieval Europe at the time are shown and labeled (the areas in light blue) for convenience.
