Schleswig (Low German: Sleswig, Danish: Slesvig, angeldän. Sljasvig) is a medium-sized town in Schleswig-Holstein on the Schlei bay. It is the district town of the Schleswig-Flensburg district, the former capital of the Duchy of Schleswig and is also known as the judicial capital of the state, because - for historical reasons - it is the seat of the state constitutional court, as well as three other higher courts and the public prosecutor's office.
The city name comes from Old Norse and means Bay of the Schlei or Port of the Schlei.
Schleswig 
			was first mentioned as Sliasthorp in 804 (Danish form: Sliestorp). 
			The ending thorp (translated village) indicates that it is a 
			sub-settlement.
The Viking settlement on Haddebyer Noor 
			called Haithabu was expanded into a trading center by King Gudfred 
			(Göttrik) in 808 and destroyed by Slavs in 1066. The question of 
			whether the germ cells of today's opposite city of Schleswig were 
			only founded after the destruction of Haithabu or whether they had 
			existed for a number of years has so far been a controversial issue 
			in research. In any case, medieval Schleswig took over Haithabu's 
			legacy as a center of Northern European trade - together with the 
			western port at Hollingstedt, which had existed since the Viking 
			Age: the land route between the Baltic and North Sea was 
			particularly short here.
Swedish Vikings under their King 
			Olaf conquered the area around 900. In 934 the East Franconian King 
			Heinrich I defeated Olaf's son Canute I and made Haithabu subject to 
			tribute. King Otto I founded the diocese of Schleswig in 947. In 
			983, the Danish Viking King Harald Blauzahn temporarily recaptured 
			the area. A few decades later, the emperors finally gave up the 
			Schleswig mark and Schleswig fell back to the Danish crown. Around 
			this time, the focus of settlement finally shifted from Haithabu to 
			today's Schleswig.
Bishop's residence in the Middle Ages
			The chronicler Adam von Bremen reported in detail as early as 1076 
			on the importance of Haithabus and Schleswig. A synod was held in 
			Schleswig under Archbishop Adalbert von Bremen, to which 
			representatives from all over Northern Europe were invited. The 
			first bishops of Schleswig were Harald (Haroldus), Poppo and 
			Rodolphus.
Saxo Grammaticus mentions the cathedral for the 
			first time in 1134. He reports that the Danish King Niels wanted to 
			flee from the brothers of the St. Knudsgilde in the cathedral, but 
			was slain because he had Jarl Knud Lavard, the son of his older 
			brother Erik Ejegod, killed in 1131, who belonged to the Schleswig 
			family had been popular.
The residence of the bishops was 
			initially a castle, which is now located under Gottorf Castle and 
			was first mentioned in 1161, when the Schleswig Bishop Occo moved 
			his seat to the castle island after the destruction of his 
			Alt-Gottorf Castle northwest of Schleswig. The castle remained in 
			the possession of the bishop until 1268, after which it was given to 
			the dukes of Schleswig in exchange for Schwabstedt castle and in 
			1340 passed to the Counts of Schauenburg who ruled Holstein. The 
			bishop's palace was then the Königsteinsche Palais at 
			Norderdomstraße 15, the Rumohrenhof. As long as the Catholic diocese 
			of Schleswig existed, the court was the center of the episcopal 
			property administration. The origins of the building go back to the 
			middle of the 15th century. The builder is said to have been Bishop 
			Nicolaus Wulf (1429–1474). After the death of the last Catholic 
			bishop Gottschalk von Ahlefeldt in 1541, the building had different 
			owners. After the cathedral chapter was dissolved in 1773, the court 
			was sold to Baron Johann Ludwig von Königstein, who had the old 
			buildings rebuilt and given their current appearance.
Schleswig had to relinquish its role as a supraregional trading 
			metropolis of the north to Lübeck in the 13th century, but at that 
			time it was still a trading center of regional importance, but in 
			the late Middle Ages the regional primacy also passed to Flensburg: 
			the Schlei was for the merchant ships of that time often not deep 
			enough.
In 1486 the missal Missale Slesvicense, set by the 
			printer Steffen Arndes, was published for the pen in Schleswig as an 
			important early North German print.
From 1344 a total of three medieval leprosories can be 
			identified in Schleswig; the first was built in today's St. Jürgen 
			district and gave the district its name because St. Georg (Low 
			German: St. Jürgen) was the patron saint of all leprosories in 
			Schleswig-Holstein. From 1392 another leprosy can be found on the 
			Gallberg, which was called Laurentius Hospital and Sikenhus 
			("hospital"). The third leprosarium was built on Hesterberg in the 
			15th century.
Residence of the Dukes of Gottorf
After the Reformation, almost all of the city's numerous churches 
			and monasteries disappeared, with a few exceptions. Some of them 
			were broken down to the foundations, which was shown during 
			excavations of the Maria Magdalena Church of the Dominican 
			monastery. On the other hand, numerous aristocratic palaces were 
			built within the city limits, in which the high officials of the 
			flourishing duchy resided.
After the division of the country 
			in 1544, the city became the residence of the dukes of 
			Schleswig-Holstein-Gottorf. These initially remained closely linked 
			to the Danish crown in terms of foreign policy, but in the 17th 
			century they led an increasingly independent policy.
At least 
			38 women were convicted and executed in witch hunts between 1548 and 
			1551. The place of execution was the market square. The trial files 
			have been preserved in the Schleswig city archive. In 2014, the 
			church and mayor Arthur Christiansen remembered the victims of the 
			witch trials in a memorial service in Schleswig Cathedral.
			Under Duke Friedrich III. From Schleswig-Holstein-Gottorf the 
			Gottorfer Hof flourished. Chancellor was Johann Adolph Kielmann von 
			Kielmannsegg. The following artists were active on the farm at this 
			time: painter Jürgen Ovens (Rembrandt's student), the carver Hans 
			Gudewerdt the Younger. The court scholar Adam Olearius described his 
			travels to Moscow (1633) and Persia (1636) in 1647. A little later, 
			the dukes also obtained an imperial privilege to found a university, 
			when Schleswig was initially also under discussion before it was 
			finally settled in Kiel.
In 1711 the two suburbs of Lollfuß 
			and Friedrichsberg were incorporated. Schleswig, Lollfuß and 
			Friedrichsberg were merged to form the "combined city of Schleswig". 
			Schleswig got a first mayor for the whole city.
After the 
			Great Northern War (1700–1721) and the associated victory of Denmark 
			over the Duchy of Schleswig-Holstein-Gottorf, the Gottorf shares in 
			the Duchy of Schleswig fell to the Danish king, who was also Duke of 
			Schleswig. This meant serious economic disadvantages for the city of 
			Schleswig, as it lost its position as the ducal residence of a 
			partially sovereign state.
After the loss of the residence 
			function for the Gottorf dukes, who had ruled the Duchy of Schleswig 
			in their shares since 1658, Gottorf Castle now became the seat of 
			the Supreme Court as well as the government and judicial authority 
			for the entire Duchy of Schleswig, later (1834) as part of a 
			judicial and administrative reform also seat of a common government 
			for both duchies (Schleswig and Holstein). Since the Duke of 
			Schleswig, as the Danish king, stayed mostly in Copenhagen, he 
			always appointed a governor to Gottorf.
Under the governor 
			Landgrave Carl von Hessen (1744–1836), Schleswig once again 
			experienced a cultural heyday. In 1836/1843 the government and the 
			court were separated and the duchy's assembly of estates was 
			re-established. The state hall of the town hall served as the 
			conference room of this “parliament”. Schleswig itself had around 
			11,000 inhabitants at that time.
From 1840, the German-Danish 
			conflict became the dominant theme in the city, whose citizens 
			mostly sided with the German Schleswig-Holsteiners. Among other 
			things, the Schleswig-Holstein song was created in Schleswig, it was 
			enthusiastically sung from 23 to 25 July 1840 at the singing 
			festival of the Schleswig-Holstein song boards in Schleswig. The 
			text comes from the Schleswig advocate Chemnitz, the music from C. 
			G. Bellmann, cantor at St. Johannis Monastery. At the same time the 
			first blue-white-red (Schleswig-Holstein colors) banner was shown.
			
In 1848 the Schleswig-Holstein uprising of the German-minded 
			population of Schleswig and Holstein against the rule of the Danish 
			king in the duchies broke out. On 23/24 April 1848 came the battle 
			of Schleswig. In this conflict, known as the “Easter Battle”, the 
			Danish troops were expelled from the city of Schleswig, but at the 
			end of the warlike years of 1851 the Kingdom of Denmark had won over 
			the Schleswig-Holstein movement. As a result, Schleswig and Holstein 
			remained as duchies initially linked to the Danish monarchy through 
			a personal union. The Duchy of Schleswig with the city of Schleswig 
			retained its position as a fiefdom of the Kingdom of Denmark, while 
			Holstein remained a member of the German Confederation.
The 
			ducal authorities within the entire Danish state were finally 
			reorganized. As a result, Schleswig lost all of the ducal government 
			authorities, and the Schleswig Assembly of Estates met from 1852 in 
			the State House in Flensburg.
After the German-Danish War in 1864, the duchies of Schleswig and 
			Holstein became an Austro-Prussian condominium. After the German War 
			(1866) they were annexed by Prussia.
With the equality of 
			Jews in the North German Confederation in 1869, a small Jewish 
			community emerged in Schleswig, which dissolved again by the First 
			World War due to the emigration of many of its members to larger 
			cities.
The city of Schleswig replaced Kiel as the seat of 
			the upper president from 1879 to 1917 and was the capital of the 
			Prussian province of Schleswig-Holstein until 1945. The 
			Schleswig-Holstein Provincial Parliament continued to meet in the 
			old state hall until 1904. During the Prussian period, from 1888 to 
			1894, the 112 meter high Schleswig cathedral tower was built.
			
Under Prussian rule, Schleswig was also a garrison town until 
			the end of the First World War. On November 9, 1866, the regimental 
			staff and the 3rd battalion of the newly established Prussian 84th 
			Infantry Regiment came to the city. The 1st and 2nd battalions 
			followed in 1890 and 1892. One battalion was in Gottorf Castle, 
			while the barracks on Moltkestrasse were built in 1892 for the other 
			battalions. In 1867 the regiment was named "Schleswigsches 
			Infanterie-Regiment Nr. 84" and was renamed in 1888 in honor of 
			General von Manstein in "Infanterie-Regiment von Manstein 
			(Schleswigsches) Nr. 84". It was dissolved again after the 1918 
			revolution. In 1866 the newly established Prussian Hussar Regiment 
			No. 16 came to Schleswig. In 1867 it was named "Schleswig-Holstein 
			Hussar Regiment No. 16". In 1872 Emperor Franz Joseph I of Austria 
			was nominally head of the regiment, the name of which was changed to 
			"Hussar Regiment Emperor Franz-Joseph of Austria, King of Hungary 
			(Schleswig-Holstein) No. 16". Gottorf Castle was his barracks until 
			it was dissolved after the revolution of 1918.
At the 
			beginning of the First World War in 1914, the church bells rang from 
			7 a.m. to 8 a.m. in Schleswig on the occasion of the mobilization 
			and the population was initially enthusiastic about the armed 
			forces. The city's public buildings, such as the seat of the 
			provincial government, the train station, the post office, the 
			Reichsbank and the town hall, were occupied by the military, and on 
			August 3 the hussar regiment moved out and on August 8 the von 
			Manstein regiment also left the city . Ultimately, Schleswig 
			suffered around 270 casualties in the First World War, for whom a 
			memorial made of gray granite was erected in 1920 in the cathedral 
			cemetery and in 1926 on the corner of Flensburger Strasse and 
			Neuwerkstrasse.
During the Weimar Republic, Count Ulrich von 
			Brockdorff-Rantzau from Schleswig became the first Foreign Minister 
			of the young German Republic. Mainly the Social Democrats, the 
			National Liberals and the German Nationals were elected (as an 
			example the result of the Reichstag election on May 20, 1928 - 
			11,557 voters in Schleswig, votes SPD 3,300, DVP 2,120, DNVP 1,313, 
			DDP 810). During the Kapp Putsch at the beginning of 1920, fighting 
			broke out in Schleswig between the garrison in Gottorf Castle, which 
			had joined the anti-democratic coup attempt, and armed workers loyal 
			to the government. In 1936 a memorial stone was erected on the 
			castle to commemorate the putschists who were killed in the process. 
			Supplemented by an explanatory inscription, this stone is still in 
			place today.
The NSDAP also had a strong base in Schleswig 
			early on. In 1925, the Schleswig local group of the party was 
			formed, whose members initially mostly came from rural areas 
			(Fahrdorf, Busdorf, Tolk). In the Reichstag election of July 1932, 
			the NSDAP received 50.7 percent of the vote, more than all other 
			political groups combined. At the end of 1932 the local NSDAP group 
			had 700 members. One reason for this success was also the situation 
			of the local newspaper market, which was dominated by the 
			Schleswiger Nachrichten. From 1930 the newspaper developed into a 
			mouthpiece for the NSDAP and thus contributed to making National 
			Socialism a majority in Schleswig. In addition, there was the high 
			affinity of the agricultural functionaries in the city and district 
			of Schleswig to the NSDAP.
During the twelve years of the “Third Reich” around 4,000 people 
			from Schleswig were members of the NSDAP. From 1933 to 1937 the 
			barracks were built on the freedom. Furthermore, in 1935 the 
			original colors of the city arms of Schleswig were changed from 
			blue-red to blue-gold. Heraldic principles are said to have been 
			decisive for this.
In 1935, the fishing settlement of Holm, 
			surrounded by water, was connected to Fischbrückstraße and the ditch 
			was filled in. With the construction of Knud-Laward-Straße as an 
			access to the barracks, the Holm has not been an island since then.
			
Communists, Social Democrats and Jews were persecuted by the 
			National Socialists and deported to concentration or extermination 
			camps. Several hundred patients from the Hesterberg and Stadtfeld 
			sanatoriums, including over 200 children, were also murdered as part 
			of the euthanasia program.
In the second half of the war 
			there were 15 camps for forced laborers with a total of around 500 
			places in Schleswig. The mostly Polish and Soviet forced laborers 
			were mostly employed in smaller companies, but around 80 of them 
			worked in the Oellerking rope and tarpaulin factory, mainly for 
			military needs.
The militarily insignificant Schleswig was 
			largely spared from the bombing of the Allies during the Second 
			World War. Various monuments (including the larger than life-size 
			Bismarck statue from Rathausmarkt, the cannon monument to Kaiser 
			Wilhelm I at the government building, the bronze figures from the 
			Reventlou-Beseler monument in front of the district court, the 
			Germania monument on upper Michaelis-Allee) were melted down to save 
			them To be able to use metal for war production. The monuments were 
			never restored even after the war ended. Instead of the Bismarck 
			monument, a fountain now adorns Schleswig's market square.
On 
			May 4, 1945, Hans-Georg von Friedeburg signed the surrender of all 
			German troops in northwest Germany, the Netherlands and Denmark on 
			behalf of the last Reich President Karl Dönitz, who had previously 
			resigned in Flensburg-Mürwik with the last Reich government. In the 
			days that followed, the city of Schleswig was also occupied by 
			British troops.
From May 10, 1945, the British confiscated 
			numerous buildings to accommodate their soldiers, including many 
			villas for the accommodation of English officers. On May 12th, 
			Gottorf Castle and its entire inventory were confiscated by the 
			British, on May 16 the Seefliegerhorst auf der Freiheit, Gewese 
			Luisenbad and its bathing beach, the boat sheds of the 
			Schleisegelclub and the beach hall. Furthermore, the owners of 
			private sailing boats had to make their ships available. The 
			Michaeliskirche served as an English garrison church since May 16. 
			By February 1948, the British seized a total of 151 houses with 
			2,490 rooms and 73,556 m² of living space, including 59 private 
			houses with 456 rooms. As a result of the confiscations, 1,800 
			people had to be housed elsewhere.
Schleswig had 26,213 
			inhabitants in the post-war period. In addition, there were 9,767 
			refugees from the former German eastern regions and evacuees from 
			the bombed cities, a total of around 36,000 people. Due to food 
			shortages, there was great hunger throughout the city.
On 
			October 12, 1945, the British occupying forces imposed a ban on 
			flags with Danish or Schleswig-Holstein colors to prevent conflict 
			of nationalities. After the Second World War, the Danish minority 
			made efforts to join the Kingdom of Denmark. Since the members of 
			the Danish minority received food aid from Scandinavia, residents 
			who professed to be part of the Danish minority after the end of 
			National Socialism were suspected by German-minded people of purely 
			material motives and insulted as "bacon Danes".
As a result 
			of the conversion of the Prussian province of Schleswig-Holstein 
			into a German federal state by the British military government from 
			1946, Schleswig lost its prominent role among the cities of 
			Schleswig-Holstein and Kiel became the state capital. Plans to move 
			the University of Kiel to Schleswig for this purpose were not 
			implemented. The British soldiers were later replaced by the 
			Norwegian military as the occupying power.
The first municipal election in the new federal state of 
			Schleswig-Holstein took place on October 24, 1948. In Schleswig, an 
			electoral alliance between the CDU and SPD won. This achieved a 
			total of 12,286 votes in Schleswig. The SSW, as a party of the 
			Danish minority, received 7187 votes from the entire population and 
			the left-wing extremist KPD 305 votes. As a result, 20 German and 7 
			Danish-minded members were elected to the city council. Of the 20 
			German representatives, 12 belonged to the CDU and 8 to the SPD. Due 
			to the clear German election victory, the city hall and the 
			cathedral tower then hoisted the blue, white and red national colors 
			that the military government had recently approved.
To 
			compensate for the loss of political and administrative functions as 
			the state capital, Schleswig also became the seat of the Higher 
			Regional Court, the State Archives, the State Museum for Art and 
			Cultural History and the State Archaeological Museum after the 
			Second World War. Schleswig is thus today a cultural and judicial 
			center of the federal state of Schleswig-Holstein.
