Territories of the Holy Roman Empire outside the Imperial Circles in the context of "Prince-electors"

The Imperial villages (German: Reichsdörfer [ˈʁaɪçsˌdœʁfɐ], singular Reichsdorf [ˈʁaɪçsˌdɔʁf]) were the smallest component entities of the Holy Roman Empire. They possessed imperial immediacy, having no lord but the Emperor, but were not estates. They were unencircled and did not have representation in the Imperial Diet. In all these respects they were similar to the Imperial Knights; the inhabitants of imperial villages were free men (being not serfs or similar feudal status).

During the early modern period, the Holy Roman Empire was divided into imperial circles (Latin: Circuli imperii; German: Reichskreise [ˈʁaɪçsˌkʁaɪzə]; singular: Circulus imperii, Reichskreis [ˈʁaɪçsˌkʁaɪs]), administrative groupings whose primary purposes were the organization of common defensive structure and the collection of imperial taxes. They were also used as a means of organization within the Imperial Diet and the Imperial Chamber Court. Each circle had a circle diet, although not every member of the circle diet would hold membership of the Imperial Diet as well.

Six imperial circles were introduced at the Diet of Augsburg in 1500. In 1512, three more circles were added, and the large Saxon Circle was split into two, so that from 1512 until the collapse of the Holy Roman Empire in the Napoleonic era, there were ten imperial circles. The Crown of Bohemia, the Swiss Confederacy and Italy remained unencircled, as did various minor territories which held imperial immediacy and mostly regrouped the semi-official Kingdom of Germany and the remains of the Kingdom of Arles.
