The name imperial government (German: Reichsregiment) denotes two organs, created in 1500 and 1521, in the Holy Roman Empire of the German Nation to enable a unified political leadership, with input from the Princes. Both were composed of the emperor or his deputy and 20 — later 22 — representatives of the Imperial States and in both cases, the imperial city of Nuremberg was the seat of government. The creation of a functional imperial government was the central plank of the Imperial Reform the princes attempted in the early 16th Century. Both attempts failed after a short time, due to the resistance of the Emperor and the divergent interests of princes.
