Reichstag (Holy Roman Empire)

The Imperial Diet (Latin: Dieta Imperii or Comitium Imperiale; German: Reichstag) was the Diet, or general assembly, of the Imperial Estates of the Holy Roman Empire and emerged from the earlier informal assemblies, known as Hoftage.

During the period of the Empire, which was dissolved in 1806, the Diet was not a parliament in today's sense; instead, it was an assembly of the various estates of the realm. More precisely, it was the convention of the Imperial Estates, legal entities that, according to feudal law, had no authority above them besides the Holy Roman Emperor (or King of the Romans) himself. The deputies convened occasionally at different cities, until in 1663 the Perpetual Diet was established at the Regensburg city hall.

The precise role and function of the Imperial Diet changed over the centuries, as did the Empire itself, in that the estates and separate territories gained more and more control of their own affairs at the expense of imperial power. Initially, there was neither a fixed time nor location for the Diet. It started as a convention of the dukes of the old Germanic tribes that formed the Frankish kingdom when important decisions had to be made, and was probably based on the old Germanic law whereby each leader relied on the support of his leading men. For example, already under Emperor Charlemagne during the Saxon Wars, the Diet, according to the Royal Frankish Annals, met at Paderborn in 777, and the Diet of Aix in 802/803 officially determined the laws concerning the subdued Saxons and other tribes.
