Imperial immediacy

Imperial immediacy (German: Reichsfreiheit or Reichsunmittelbarkeit) was a privileged constitutional and political status rooted in German feudal law under which the Imperial estates of the Holy Roman Empire such as Imperial cities, prince-bishoprics and secular principalities, and individuals such as the Imperial knights, were declared free from the authority of any local lord and placed under the direct ("immediate", in the sense of "without an intermediary") authority of the Holy Roman Emperor, and later of the institutions of the Empire such as the Diet (Reichstag), the Imperial Chamber of Justice and the Aulic Council.

The granting of immediacy began in the Early Middle Ages, and for the immediate bishops, abbots, and cities, then the main beneficiaries of that status, immediacy could be exacting and often meant being subjected to the fiscal, military, and hospitality demands of their overlord, the Emperor. However, with the gradual exit of the Emperor from the centre stage from the mid-13th century onwards, holders of imperial immediacy eventually found themselves vested with considerable rights and powers previously exercised by the emperor.

As confirmed by the Peace of Westphalia in 1648, the possession of imperial immediacy came with a particular form of territorial authority known as territorial superiority (German: Landeshoheit or Latin: superioritas territorialis in documents of the time).[1][2] In today's terms, it would be understood as a limited form of sovereignty.
