A map of the Imperial Circles as at the beginning of the
16th century. States that were not part of a circle are shown in white.
An 'Imperial Circle' (in
German ''Reichskreis'', plural ''Reichskreise'') was a regional grouping of states of the
Holy Roman Empire, primarily for the purpose of organizing a common defense and of collecting imperial taxes, but also as a means of organization within the ''
Reichstag'' (Imperial Diet).
Each circle had a ''Kreistag'' (Circle Diet), although not every member of the ''Kreistag'' would also be a member of the ''Reichstag'' as well.
Formation of the circles
Initially six circles were created in
1500 as part of the ''
Reichsreform'' (Imperial Reform):
★ the
Bavarian Circle
★ the
Swabian Circle
★ the
Upper Rhenish Circle
★ the
(Lower Rhenish-)Westphalian Circle
★ the
Franconian Circle
★ the
Lower Saxon Circle
A further four circles were created in
1512:
★ the
Burgundian Circle
★ the
Austrian Circle
★ the
Upper Saxon Circle
★ the
Electoral Rhenish Circle
These ten circles remained largely unchanged until the early
1790s, when the
Wars of the French Revolution brought about significant changes to the political map of the Empire.
States outside the circles
A number of states were left outside of any circle:
★ The lands of the Bohemian crown (
Bohemia,
Moravia,
Silesia, and
Upper and
Lower Lusatia)
★ The territories of the
Swiss Confederation, which while nominally subject to the Empire, had established quasi-independence in 1499
★ The various territories of northern
Italy, which were also virtually independent
★ A small number of minor states, such as the County of
Montbéliard (Mömpelgard) and the Lordship of
Schmalkalden
