A blank map of the Holy Roman Empire during the time of the Hohenstaufen Emperors (circa 1250). The map also shows the Kingdom of Sicily, which was ruled in a personal union with the Empire at that time.
Note that while it uses the same scheme as standard location maps, this map technically does not conform to the standard, as it is on in equirectangular projection. Therefore grid lines for latitude and longitude are also included.

The map is a vectorised version of this map from Professor G. Droysens Allgemeiner Historischer Handatlas, which was published in 1886 by R. Andrée Plate.
