Regensburg
The year 90 marked the construction of Castra Regina, a Roman military fort established at the confluence of the Danube, Naab, and Regen rivers. This fortress served as the northernmost point of the Danube frontier under Emperor Marcus Aurelius during the reign of Legio III Italica. Archaeological evidence places the original camp east of today's Obere Bachgasse and west of Schwanenplatz within the city core. By the late Roman period, the settlement had evolved into a bishopric seat, laying the groundwork for centuries of religious authority. The Agilolfing ruling family made Regensburg their capital from the early sixth century until the thirteenth century. In 739, St Boniface re-established the Bishopric of Regensburg, solidifying its ecclesiastical importance across southern Germany. Charlemagne hosted an ecclesiastical assembly in 792 that condemned adoptionism, a heretical doctrine taught by Elipandus of Toledo and Felix of Urgell. Louis the German became ruler of Eastern Francia after the Carolingian Empire partitioned in 843, making Regensburg his seat two years later. Fourteen Bohemian princes traveled to the city in 845 to receive baptism, initiating the Christianization of the Czech lands. Arnulf of Carinthia died at Regensburg on the 8th of December 899, marking the end of an era for early medieval Bavarian rulers.
The year 1663 began a permanent political arrangement when the Imperial Diet established its headquarters in Regensburg, creating what historians call the Perpetual Diet. This unique configuration lasted until 1806, transforming the city into one of Europe's most significant diplomatic hubs. The town contained five independent states within its boundaries: the Protestant city itself, the Roman Catholic bishopric, and three monasteries including St Emmeram, Niedermünster, and Obermünster. Each entity held voting rights at the Imperial Diet, creating an unprecedented political complexity. The Prince of Thurn and Taxis served as Emperor's Commissary-Principal for many years, residing permanently in the city. Charles V met Barbara Blomberg at the Golden Cross Inn, where their son John of Austria was born in 1547. The Old Town Hall housed the Imperial Diet chambers from 1663 to 1806, now preserved as part of the Reichstagsmuseum. Napoleon himself commanded French forces during the Battle of Ratisbon between April 19th and 23rd, 1809, causing severe damage to approximately 150 houses. Carl von Dalberg unified the bishopric, monasteries, and town into the Principality of Regensburg before ceding control to Bavaria in 1810.
Construction of the Stone Bridge began around 1135 and concluded by 1146, opening major international trade routes between northern Europe and Venice. Knights of the Second and Third Crusades crossed this bridge on their journey to the Holy Land, establishing its strategic importance. By the year 1000, the population had grown from 23,000 inhabitants in 800 to reach 40,000 residents. Wealthy patrician families competed to build the tallest towers, with the Goldener Turm completed on Wahlenstrasse in 1260. The city became a cultural center for southern Germany, celebrated for its gold work and fine fabrics. The Regensburger Domspatzen cathedral choir continues to perform liturgical music at St Peter's Cathedral today. The cathedral itself was founded in 1275 and completed in 1634, though its towers were not finished until 1869. The Adler-Apotheke pharmacy near the cathedral was established in 1610 and remains one of the oldest operating pharmacies in the region. The stone bridge served as both a commercial artery and a military crossing point throughout medieval history.
The year 1519 marked the expulsion of approximately 500 Jews from Regensburg following the death of Emperor Maximilian I. Local guilds and the city council confiscated Jewish property and demolished the centuries-old synagogue and much of the Jewish quarter. The medieval Jewish cemetery, one of the oldest in the region, was destroyed with many gravestones broken or reused in construction projects. During Kristallnacht on the 9th of November 1938, Nazi forces destroyed the Regensburg Synagogue and arrested around 220 Jews. Some deportees were sent to Dachau concentration camp while others faced deportation to Piaski in German-occupied Poland or Theresienstadt Ghetto in Czechoslovakia by 1942. A subcamp of Flossenbürg operated within the city during March and April 1945, housing 460 forced laborers of various nationalities. Forty prisoners died at this subcamp before liberation. Stolpersteine memorial stones now honor those deported during the Nazi era, scattered across the city's streets. The community remained absent for several centuries until Jews were permitted to resettle in the early modern period.
