  Throughout the first half of its history the Holy Roman Empire was reigned over by a travelling court. Kings and emperors toured between the numerous Kaiserpfalzes (Imperial palaces), usually resided for several weeks or months and furnished local legal matters, law and administration. Most rulers maintained one or a number of favourites Imperial palace sites, where they would advance development and spent most of their time: Charlemagne (Aachen from 794), Otto I (Magdeburg, from 955), Frederick II (Palermo 1220–1254), Wittelsbacher (Munich 1328–1347 and 1744–1745), Habsburger (Prague 1355–1437 and 1576–1611; and Vienna 1438–1576, 1611–1740 and 1745–1806).
  
  This practice eventually ended during the 16th century, as the emperors of the Habsburg dynasty chose Vienna and Prague and the Wittelsbach rulers chose Munich as their permanent residences (Maximilian I's "true home" was still "the stirrup, the overnight rest and the saddle", although Innsbruck was probably his most important base; Charles V was also a nomadic emperor). Vienna became Imperial capital during the 1550s under Ferdinand I (reigned 1556–1564). Except for a period under Rudolf II (reigned 1570–1612) who moved to Prague, Vienna kept its primacy under his successors. Before that, certain sites served only as the individual residence for a particular sovereign. A number of cities held official status, where the Imperial Estates would summon at Imperial Diets, the deliberative assembly of the empire.
  
  The Imperial Diet (Reichstag) resided variously in Paderborn, Bad Lippspringe, Ingelheim am Rhein, Diedenhofen (now Thionville), Aachen, Worms, Forchheim, Trebur, Fritzlar, Ravenna, Quedlinburg, Dortmund, Verona, Minden, Mainz, Frankfurt am Main, Merseburg, Goslar, Würzburg, Bamberg, Schwäbisch Hall, Augsburg, Nuremberg, Quierzy-sur-Oise, Speyer, Gelnhausen, Erfurt, Eger (now Cheb), Esslingen, Lindau, Freiburg, Cologne, Konstanz and Trier before it was moved permanently to Regensburg.
  
  Until the 15th century the elected emperor was crowned and anointed by the Pope in Rome, among some exceptions in Ravenna, Bologna and Reims. Since 1508 (emperor Maximilian I) Imperial elections took place in Frankfurt am Main, Augsburg, Rhens, Cologne or Regensburg.
  
  In December 1497 the Aulic Council (Reichshofrat) was established in Vienna.
  
  In 1495 the Reichskammergericht was established, which variously resided in Worms, Augsburg, Nuremberg, Regensburg, Speyer and Esslingen before it was moved permanently to Wetzlar.
