As an imperial city, Aachen held certain political privileges that allowed it to remain independent of the troubles of Europe for many years. It remained a direct vassal of the Holy Roman Empire throughout most of the Middle Ages. It was also the site of many important church councils, including the Council of 837 and the Council of 1166, a council convened by the antipope Paschal III.
