Schweinfurt

Traces of settlement as early as 7500 years ago can be detected on today's urban area at various places. The first settlement of the historic Schweinfurt (Village Old Town) was also on the Main, between the two streams Höllenbach and Marienbach,[5] 1 km east of the later founded imperial city, which corresponds to the old town today. The Village Old Town is in its origins at least 2100 years old.

The first documentary mention Schweinfurts (village old town) took place in the year 791.[5] Schweinfurt gained importance in 941 with the mention of Count Berthold as the first member of the House of the Counts of Schweinfurt.[6] He occupied an important position in the central Reich territory, the Duchy of Franconia. Berthold gave the king of East Francia Otto I. (936-973), who in 962 became Roman-German Emperor, valuable weapons aid against rebellious tribal dukes. As thanks Berthold of Otto I received the counties for the Folkfeld- and the Radenzgau and the Margraviate for the Nordgau, about the present-day Upper Palatinate. Thus he was and from 980 his son Henry the most powerful secular nobility in the area of today's northern Bavaria.

Later supported Count Henry of Schweinfurt (called: Hezilo) the East Frankish Henry II (1002-1024, from 1014 Roman-German Emperor) in the royal election of 1002 and was awarded the Duke dignity of Bavarians. After the election, however, Henry II did not fulfill the promise. Thereupon it came to the Schweinfurt Feud in 1003.[6] Count Heinrich lost all his possessions. The confiscated royal goods formed the core of the new bishopric of Bamberg. Hezilo, however, retained his possessions around the castle hill Peterstirn. The family, in which Judith of Schweinfurt became a central figure in the history of the old Schweinfurt city, died in the male line of 1057 and at the latest this year marks the undisputed end of the important role of the Margraves of Schweinfurt.

To the beginnings of today's old town from the 12th century, 1 km west of the previous settlement between the both streams Marienbach and Höllenbach, there are different views. The from a gradual construction to a planned Civitas Imperii (imperial city), so a founding city, by Emperor Frederick I Barbarossa, using existing royal estate, rich. In the struggle for supremacy in Main Franconia (region around the River Main) between the Henneberger and the Bishop of Würzburg, the city was destroyed between 1240 and 1250 (First City Spoilage). However, it is controversial whether this destruction was still in the old settlement between Höllenbach and Marienbach and thus a reason for the rebuilding of the city on the farther west, today's site was or whether the destruction took place here already. In a letter from King William of Holland dated January 9, 1254, it is said that Schweinfurt used to be imperial city (... Swinforde, que olim imperii civitas fuerat). It remains unclear whether rights have ever been withdrawn from the city or whether only reference is made to the city's destruction. However, this letter is the first documentary evidence of Schweinfurt as imperial city and thus as a place with city rights.[7]

Restored walls of the former Reichsburg at the old city district Zürch

The (inner) city fortification of the new city was built and first documented in 1258, it is still largely preserved on Marienbach today. A document from 1282 signed by Rudolf I of Habsburg states that Schweinfurt was a free city within the Holy Roman Empire.[7] By pledge 1309 Schweinfurt came to the House of Henneberg, who maintained from 1310 to 1427 a Reichsburg (castle of the empire) in the old Schweinfurt city district Zürch. The danger of being estranged from the Empire in the long run could only be banned by large financial sacrifices by self-triggering (1361/1385). As a result, numerous royal privileges strengthened the municipality in legal and economic terms.

In the 15th century began the construction of a territory around the core city, which lasted until 1620. In 1436, the fishermen's settlement of Fischerrain, which borders on the city wall and lies just to the southwest, whose origins lie in the darkness of history, was incorporated into the city. Due to positive economic development, the city can acquire the suburb of Oberndorf in 1436. 1436/37 received the advice of the city from the Teutonic Knights for 18,000 guilders the castle on the Peterstirn and the associated land area with the villages Zell and Weipoltshausen, which belongs to Üchtelhausen today.

Imperial city Schweinfurt Territory 1620–1802, and surrounding areas

Schweinfurt joined the Reformation relatively late, in 1542 since the city, together with neighboring imperial villages and imperial villages, was completely surrounded by the Catholic Hochstift Würzburg.[8] In a confession change had to be expected military assault. The patron of the city, Count Wilhelm von Henneberg, did not offer sufficient support.

In the course of the Second Margrave War, the city was looted in 1554 and set on fire. This went as the Second City Spoilage in the city history (First City Spoilage see: 8th to 13th centuries). The reconstruction dragged on until 1615. In this form, the old town, with the exception of later modernized fortifications, remained almost unchanged until the early 19th century. In 1609 the city joined the Protestant Union. The imperial city territory was supplemented 1620 also still around Madenhausen,[8] which also belongs to Üchtelhausen today. Due to the acquisitions, the territory of the imperial city now had an extension of 17 km from southwest to northeast. As a result of the city of Schweinfurt on the knight canton of Baunach a nearly continuous Protestant corridor was created by the Hochstifte Würzburg and Bamberg in the Protestant Duchy of Saxony.[9]

Schweinfurt joined the Protestant Union in 1609. In the Thirty Years' War it was occupied by Gustavus Adolphus, who erected fortifications, the remains of which are still extant.[10] In 1652 the four doctors Johann Laurentius Bausch, Johann Michael Fehr, Georg Balthasar Wolfahrt and Balthasar Metzger founded the Academia Curiosorum in Schweinfurt, which is known today as the German Academy of Life Scientists, "Leopoldina".

Schweinfurt remained a free imperial city until 1802, when it passed to the Electorate of Bavaria. Assigned to the grand duke of Würzburg in 1810, it was granted to the Kingdom of Bavaria four years later.[10] The first railway junction was opened in 1852. In the following years Schweinfurt became a world leading centre for the production of ball bearings.[11] This was to lead to grievous consequences for the city during World War II.

The year 1770 marked the beginning of the industrialization of the city, with its 250-year-old industrial history. In the first century of industrialization, the chemical and paint industry started in Schweinfurt, with the construction of the Wolf's lead white mill at the Bleiweißmühlenwehr. According to Dr. Ferdinand Gademann (1880-1969), it was the oldest German lead white factory. In 1780 the factory was taken over by Johann Martin Schmidt. Further factory-similar plants of this kind originated at the Bellevue and in the neighboring suburb Niederwerrn.

Following the Reichsdeputationshauptschluss, Schweinfurt came to Bavaria in 1803, two years before the Kingdom of Bavaria was founded. 4000 people demonstrated against the Anschluss at the Rossmarkt. After the interim membership of the Grand Duchy of Würzburg (1810-1814), Schweinfurt fell in 1814 to the Kingdom of Bavaria. The villages belonging to the imperial city territory were spun off. As a result, Schweinfurt lost about two thirds of its territory.

1852 took place with the opening of the Ludwigs-Westbahn from Bamberg to the new Schweinfurt Stadt station the connection to the railway network. With the construction of the line to Bad Kissingen (1871) and the Schweinfurt–Meiningen railway (1874) Schweinfurt became a railway junction. In 1874, a large marshalling and central station was built 3 km west of the city station, at that time on Oberndorf district, the so-called Central Station and today's Schweinfurt Hauptbahnhof at the Bamberg–Rottendorf railway. It was created in a far-sighted manner amidst fields as a passenger and goods main station, with the aim of leaving as much room for the expected industrialization of the station, which also took place here until the end of the 1930s was. The Schweinfurt tram was the first municipal tram in Bavaria from 1895 to 1921 to connect the Schweinfurt Hauptbahnhof with the town center.

Unlike many other cities, the 1930s were one of the most important epochs of urban development in Schweinfurt. The number of employees of major metalworking companies rose to 20,700 by 1939. This led to a construction boom and set the course for modern urban development.

Operation Overlord with combined bomber offensive June 1944: Schweinfurt (checkered hatching in the German center) was the only primary target of the Allies in Bavaria

In 1939, Schweinfurt produced most of Nazi Germany's ball bearings, and factories such as the Schweinfurter Kugellagerwerke became a target of Allied strategic bombing during World War II to cripple tank and aircraft production. Schweinfurt was bombed 22 times during Operation Pointblank by a total of 2,285 aircraft.

The Schweinfurt-Regensburg mission caused an immediate 34% loss of production[12] and all plants but the largest were devastated by fire. Efforts to disperse the surviving machinery began immediately and the Luftwaffe deployed large numbers of interceptors along the corridor to Schweinfurt.[13] Bombing also included the Second Raid on Schweinfurt on 14 October 1943 ("called Black Thursday because of the enormous loss of aircraft (60) and lives (600+)") and Big Week in February 1944.

Although losses of production bearings and machinery were high and much of the industrial and residential areas of the town were destroyed, killing more than a thousand civilians, the factories were restored to production and the industry dispersed. Although German planners initially thought it essential to purchase the entire output of the Swedish ball-bearing industry, losses in the production of bearings were actually made up from surpluses found within Germany in the aftermath of the first raid. The decentralized industry was able to restore output to 85% of its pre-bombing level. Hitler made restoration of ball bearing production a high priority and massive efforts were undertaken to repair and rebuild the factories, partly in bomb-proof underground facilities.

The 42nd Infantry Division (United States) entered Schweinfurt on 11 April 1945 and engaged in house-to-house fighting.[13]^:2 On 12 April an internment camp at Goethe-Schule[13]^:2 held male civilians aged 16–60.[14]

USAG Schweinfurt Ledward Barracks Headquarter Building

After the war Schweinfurt became a stronghold of the U.S. military and their dependants. Thus Schweinfurt recovered relatively quickly from its third period of destruction. The tank barracks renamed Ledward Barracks in 1946, became the headquarters of the newly founded U.S. Army Garrison Schweinfurt (USAG Schweinfurt). The U.S. Army took over the Luftwaffe Airfield as Schweinfurt Army Heliport and renamed the air base to Conn Barracks. In the course of time, until 2014, they were expanded into large barracks with many hangars, administration buildings, a large event hall, church and sports facilities.

From the 1950s to the late 1990s, a civilian infrastructure similar to that of a small American town was successively built in the northwest of Schweinfurt. As a result of the closure of many other German U.S. sites, Schweinfurt eventually became one of Europe's largest U.S. locations. Including the Brönnhof training area the USAG Schweinfurt covered a total area of 29 km². Schweinfurt formerly hosted the U.S. Army Garrison Schweinfurt, which the U.S. Army closed on 19 September 2014 due to an ongoing effort to concentrate the U.S. military's footprint in Germany to fewer communities.[15]

A quick, scheduled rebuilding of the town was not necessary due to the degree of destruction of 40 to 45% (see: Cityscape). Like many other West German cities and communities, Schweinfurt also experienced an unprecedented economic miracle in the 1950s and 1960s, and large-scale industry boomed. To counteract the labor shortage, guest workers were recruited from 1960 onwards.

Most of the postwar construction projects were realized under the aegis of Mayor Georg Wichtermann (SPD, 1965-1974), in the city governed by the SPD by an absolute majority. Numerous new residential districts were created. By the Jump over the River Main (starting from 1963)[6] developed south of the Main River the commercial park Port East and the new industrial area Port West. The infrastructure was expanded, with the Main Port (1963) and today's University of Applied Sciences Würzburg-Schweinfurt (1971).

After successful reconstruction and the boom years, the time of Mayor Kurt Petzold (SPD, 1974–1992) was marked by consolidation, but also by the oil crisis and recessions, with job cuts in the local large-scale industry. The old town renovation began in 1979,[6] as the starting point of a 40-year-long transformation of the town that has continued to this day, with a change in image, from the gray mouse industrial town to a town with a high quality of life. In 1991, the large Leopoldina Hospital was opened.[6]

In a town dominated by the SPD, the CSU succeeded in 1992 for the first time to make the Lord Mayor, with the political cross-starter Gudrun Grieser. The Bavarian state government under the then Prime Minister Edmund Stoiber (CSU) sympathetically accompanied the historical change of power and parts of the Bavarian State Social Court and the Bavarian State Statistics Office were relocated from Munich to Schweinfurt. During Grieser's term of office, the economic situation stabilized starting in the mid-1990s, with 4,500 new industrial jobs and around 6,000 jobs in the service sector. Trade tax revenue rose to a record high.

In the Grieser era, the town's new motto, Industry and Art, was developed. A large number of projects, in cooperation with the construction officer Jochen Müller (SPD) gave the town a new face, set new, nationally recognized symbols in architecture and were honored with numerous architecture prizes. Among the many realized projects are the new Industrial Park Gewerbepark Maintal (since 1995),[6] the Museum Georg Schäfer (2000),[6] the Maininsel Conference Center (2004), the Stadtbücherei Ebracher Hof (2007), the Kunsthalle Schweinfurt (art gallery, 2009), the Stadtgalerie Schweinfurt, a 300 m long shopping mall 2009) with redesign of the Weststadt (westend) and the new Schweinfurt Mitte station, the Youth Hostel (2009), the Health Park Schweinfurt (2009) and the Campus 2 of the University of Applied Sciences Würzburg-Schweinfurt. The era of Grieser remains to this day shaping the town, like no other epoch after the reconstruction and it changed the town's image lasting positive.

In 1998, German and American veterans and survivors of the bombing raids came together to erect a war memorial to the fallen. 2004 startet the Unterfrankenshuttle (Lower Franconia Shuttle) of the Erfurter Bahn (EB) regional railway with lines from Schweinfurt to other parts of Lower Franconia and to South Thuringia.

The New Hadergasse Project was implemented under the current mayor Sebastian Remelé (CSU, since 2010). Trade tax receipts continued to rise and the town was able to save reserves. These are currently being used for the mammoth U.S. conversion project, which is currently one of the five largest military conversion projects in Germany. The i-Campus Schweinfurt in the former Ledward Barracks and the new district of Bellevue in the former Askren Manor Housing Area deserve special mention.

Schweinfurt has a central location in Germany and is located about 40 km from Baden-Württemberg, Hesse and Thuringia, in the middle of Main Franconia, Germanic-speaking Europe and the European Union. Schweinfurt lies on the river Main, which connects the North Sea with the Black Sea via the Rhine-Main-Danube Canal. While not being part of any metropolitan area, the town is situated between the cities of Frankfurt (110 km west) and Nuremberg (90 km southeast), both with international airports.

Schweinfurt also has a natural location in the Franconian wine country, at the Schweinfurter Rhön, with the National Natural Heritage Brönnhof and is surrounded by Haßberge Hills, Steigerwald, Rhön and Spessart, with several natural parks and a biosphere reserve.[16] In sight are Steigerwald, Gramschatzer Forest and Rhön. The town is located in a climatically contrasting region, between the summer hot Mainfränkischen Plates in the south and the low mountain range in the north, with international winter sports in Oberhof.

Schweinfurt itself is also a town of great contrasts, in terms of topography, use and population structure. The bourgeois east lies on the foothills of the Schweinfurter Rhön, is intersected by valleys with streams, with the above the Marienbach located old town and numerous detached houses, on the edge with vineyards and the town forest. The west, with the town center, main station and (former) working-class neighborhoods, has a high proportion of migrants. The almost uninhabited south is the largest contiguous industrial area in Bavaria.

As a result of the fall of the Iron Curtain, the economic and geographical situation of Schweinfurt changed fundamentally. In 2005, the Thuringian Forest Autobahn 71 Erfurt-Schweinfurt was completed as a transport Project German Unity No. 16. In 2017 Schweinfurt gained further centrality with the 10 billion Euro transport Project German Unity No. 8. Berlin is now under three and a half hours, Munich from 2:33 hours and Hamburg from 3:57 hours reachable, now two high-speed lines, with change in Bamberg and Würzburg. Berlin and Munich are about three quarters of an hour faster from Schweinfurt than from Frankfurt. Paris is in 6:22 hours reachable. As part of the Deutsche Bahn Long-Distance Transport Offensive Schweinfurt receives no later than December 2028 a direct Inter City (IC) connection, through the new IC Bamberg-Stuttgart-Tübingen.

Viticulture has probably been practiced in the city for well over 1000 years. At the beginning of the 19th century, Schweinfurt was an important Franconian wine-growing and wine-trading town. At the end of the imperial city period in 1802 there were around 320 hectares of vines, which corresponds to today's largest Franconian wine-growing town in Nordheim am Main. Large parts of today's district, right up to the edge of the old town, are located on former vineyards. Goethe appreciated the Schweinfurt wine and had large quantities delivered. Today, with only 3.54 hectares of vineyards (2017),[17] the local viticulture has hardly any economic, but still cultural importance for the self-awareness and way of life of the city.

Vineyard Schweinfurter Peterstirn

The phylloxera appeared in Franconia in 1902 and hit the Schweinfurt area particularly hard.[18] Since the 1980s, viticulture with the leading variety Silvaner has been carried out as planned in the historic wine locations of Peterstirn and Mainleite. Due to the almost complete interruption of winegrowing, the vineyards were spared the major land consolidation of the 1970s, during which the historical structures were mostly destroyed. The small wine-cultural landscape at Peterstirn Palace remained intact. There is a family-owned winery on Peterstirn, where a wine festival takes place twice a year.

In the Bavarian territorial reform no suburbs were incorporated into the city of Schweinfurt, which is why the urban area includes only the core city and incorporated in 1919 Oberndorf. The urban area was divided into 23 statistical districts, which are summarized in 15 districts (bold font in the table). For a long time, the Bergl was the most populous district, with 13,000 inhabitants around 1970. With only 9,163 inhabitants at the end of 2017, it was only second, after the city center, with 11,276 inhabitants.[19]
