The Holy Roman Empire was a highly decentralized state for most of its history, composed of hundreds of smaller states, most of which operated with some degree of independent sovereignty. Although in the earlier part of the Middle Ages, under the Salian and Hohenstaufen emperors, it was relatively centralized, as time went on the Emperor lost more and more power to the Princes. The membership of the Imperial Diet in 1792, late in the Empire's history but before the beginning of the French Revolutionary Wars, gives some insight as to the composition of the Holy Roman Empire at that time.
The year 1792 was just before the vast changes inspired by the French Revolutionary incursions into Germany. The empire was, at that time, divided into several thousand immediate (unmittelbar) territories, but only about three hundred of these had Landeshoheit (the special sort of sovereignty enjoyed by the states of the Empire), and had representation in the Imperial Diet of the Holy Roman Empire (German Reichstag). The Imperial Diet was divided into three so-called collegia—the Council of Electors, the Council of Princes, and the Council of Cities. As those who received votes had gradually changed over the centuries, many princes held more than one vote. Certain territories which had once held votes in the Diet, as for instance the County of Waldeck or the Duchy of Jülich-Kleve-Berg, no longer retained them, due to the extinction of a dynasty or other causes.
The council included the following eight members:
The King of Bohemia (also Archduke of Austria and King of Hungary) (Emperor Leopold II)
The Archbishop of Mainz (Friedrich Karl Joseph von Erthal)
