Imperial immediacy ( or ) 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 (), 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 ( or in documents of the time). In today's terms, it would be understood as a limited form of sovereignty. Gradations Several immediate estates held the privilege of attending meetings of the in person, including an individual vote (): the seven Prince-electors designated by the Golden Bull of 1356 the other Princes of the Holy Roman Empire secular: Dukes, Margraves, Landgraves, et al. ecclesiastical: Prince-Bishops, Prince-Abbots and Prince-Provosts. They formed the Imperial Estates, together with 99 immediate counts, 40 Imperial prelates (abbots and abbesses), and 50 Imperial Cities, each of whose "banks" only enjoyed a single collective vote (). Further immediate estates not represented in the were the Imperial Knights as well as several abbeys and minor localities, the remains of those territories which in the High Middle Ages had been under the direct authority of the Emperor and since then had mostly been given in pledge to the princes. At the same time, there were classes of "princes" with titular immediacy to the Emperor which they exercised rarely, if at all. For example, the Bishops of Chiemsee, Gurk, and Seckau (Sacken) were practically subordinate to the prince-bishop of Salzburg, but were formally princes of the Empire. Advantages and disadvantages
