Having probably learned from experience that there was not much to gain from active, and costly, participation in the Imperial Diet's proceedings due to the lack of empathy of the princes, the cities made little use of their representation in that body. By about 1700, almost all the cities with the exception of Nuremberg, Ulm and Regensburg, where by then the
Perpetual Imperial Diet was located, were represented by various Regensburg lawyers and officials who often represented several cities simultaneously. Instead, many cities found it more profitable to maintain agents at the
Aulic Council in Vienna, where the risk of an adverse judgment posed a greater risk to city treasuries and independence. in 1725 of 1803 and 1806. The territory of most Free Imperial Cities was generally quite small but there were exceptions. The largest territories formed in what is now Switzerland with cities like Bern, Zürich and Luzern, but also cities like Ulm, Nuremberg and Hamburg in what is now Germany possessed substantial hinterlands or fiefs that comprised dozens of villages and thousands of subject peasants who did not enjoy the same rights as the urban population. At the opposite end, the authority of Cologne, Aachen, Worms, Goslar, Wetzlar, Augsburg and Regensburg barely extended beyond the city walls. Initially, the constitution of the free and imperial cities was republican in form but between 1548 and 1552, as a result of the defeat of the
Schmalkaldic League, the democratic constitutions of 28 cities were replaced by constitutions that concentrated the power in the hand of an oligarchic Small Council. Those self-perpetuating councils were composed almost exclusively of
patricians, who belonged to the most economically significant
burgher families who had asserted themselves politically over time. Below them, with a say in the government of the city, were the citizens or burghers, the smaller, privileged section of the city's permanent population whose number varied according to the rule of citizenship of each city. There were exceptions, such as
Nuremberg, where the patriciate ruled alone. To the common town dwellerwhether he lived in a prestigious Free Imperial City like Frankfurt, Augsburg or Nuremberg, or in a small market town such as there were hundreds throughout Germanyattaining burgher status ('''') could be his greatest aim in life. The burgher status was usually an inherited privilege renewed pro-forma in each generation of the family concerned but it could also be purchased. At times, the sale of burgher status could be a significant item of town income as fiscal records show. The '''' was local and not transferable to another city. The burghers were usually the lowest social group to have political power and privilege within the Holy Roman Empire. Below them was the disenfranchised urban population, maybe half of the total in many cities, the so-called "residents" ('''') or "guests": smaller artisans, craftsmen, street venders, day laborers, servants and the poor, and those whose residence in the city was temporary, such as wintering noblemen, foreign merchants, princely officials, and so on. Urban conflicts in Free Imperial Cities, which sometimes amounted to class warfare, were not uncommon in the Early Modern Age, particularly in the 17th century (Lübeck, 1598–1669; Schwäbisch Hall, 1601–1604; Frankfurt, 1612–1614; Wetzlar, 1612–1615; Erfurt, 1648–1664; Cologne, 1680–1685; Hamburg 1678–1693, 1702–1708). Sometimes, as in the case of Hamburg in 1708, the situation was considered sufficiently serious to warrant the dispatch of an Imperial commissioner with troops to restore order and negotiate a compromise and a new city constitution between the warring parties. The number of Imperial Cities shrank over time until the Peace of Westphalia. There were more in areas that were very fragmented politically, such as Swabia and Franconia in the southwest, than in the North and the East where the larger and more powerful territories, such as Brandenburg and Saxony, were located, which were more prone to absorb smaller, weaker states. In the 16th and 17th century, a number of Imperial Cities were separated from the Empire due to external territorial change. and its liberal tradition, the need was devised to compensate
Prussia for territorial losses under the
Greater Hamburg Act, and Lübeck was annexed to Prussia in 1937. In the
Federal Republic of Germany which was established after the war, Bremen and Hamburg, but not Lübeck, became constituent
states, a status which they retain to the present day.
Berlin, which had never been a Free City in its history, received the status of a state after the war due to its special position in divided post-war Germany.
Regensburg was, apart from hosting the
Imperial Diet, a most peculiar city: an officially Lutheran city that was the seat of the Catholic prince-bishopric of Regensburg, its prince-bishop and cathedral chapter. The Imperial City also housed three Imperial abbeys:
St. Emmeram, and . They were five
immediate entities fully independent of each other existing in the same city. ==Image gallery==
