The History of Szczecin () dates back to the 8th century. Throughout its history the city has been part of Poland, Denmark, Sweden and Germany. Since the Middle Ages, it is one of the largest and oldest cities in the historic region of Pomerania, and today, is it the largest city in northwestern Poland.
Prehistory
Tacitus located the East Germanic tribe of the Rugians in the area around Szczecin, as do modern historians. The Rugians where driven out during the Great Migrations in the 5th century AD.
Slavonic stronghold, medieval Poland (8th–12th century)
Another stronghold was built in the 8th century-first half of the 9th century at the ford of the Oder River, (at the same location where later was a ducal castle) and a few craftsmen, fishermen and traders settled in the vicinity. Later it became the main centre of a Western Slavic tribe of Ukrani (Wkrzanie) living in the fork of the Oder between the main branch and the Randow River. Several Triglav temples existed nearby. Szczecin became part of the emerging Polish state under its first historic ruler Mieszko I of Poland in 967, part of which it remained for several decades.
After the decline of Wolin in the 12th century, Stetinum became one of the most important and powerful cities of the Baltic Sea south coasts, having some 5,000 inhabitants. In a winter campaign of 1121–1122, the area was subjugated by Boleslaw III of Poland, who invited the Catholic bishop Otto of Bamberg to baptize the citizens (1124). Wartislaw I, Duke of Pomerania is recorded as the local duke during this time. Wartislaw managed to expand his duchy westward, thereby forming the territorial body of the later Duchy of Pomerania, and organized the second visit of Otto in 1128. At this time the first Christian church of St. Peter and Paul was erected. It remained under Polish suzerainty until the fragmentation of Poland following the death of Boleslaw III of Poland and afterwards remained the capital of the separate Duchy of Pomerania, still ruled by the local Slavic Griffin dynasty, of which Wartislaw I was the first historical ancestor, for the centuries to come, until its extincion in 1637. Szczecin did not lose its capital status even during the partitions of Pomerania and always was seat of Pomeranian dukes.
From the late 12th century the city briefly fell under the overlordship of Saxony from 1164, Denmark from 1173, Holy Roman Empire from 1181 and again Denmark from 1185,Werner Buchholz, Pommern, Siedler Verlag, 1999, p. 34-35 (in German) however, local dukes still maintained very close ties with the fragmented Polish realm, and Władysław III Spindleshanks (future Polish monarch) stayed at the court of Bogusław I, Duke of Pomerania in Szczecin in 1186, on behalf of his father, Duke of Greater Poland Mieszko III the Old, who also periodically was the High Duke of Poland. The ducal mint in Szczecin was founded around 1185.
Capital of the Duchy of Pomerania (12th century–1630)
Szczecin was held by Denmark until 1235, when it fell under the suzerainty of the multi-ethnic Holy Roman Empire.Thomas Riis, Studien Zur Geschichte Des Ostseeraumes IV. Das Mittelalterliche Dänische Ostseeimperium, 2003, p. 48 In the second half of the 12th century, a group of German tradesmen (from various parts of the Holy Roman Empire) settled in the city around St. Jacob's Church, which was founded by Beringer, a trader from Bamberg, and consecrated in 1187. For centuries the dukes invited German settlers to colonize their land and to found towns and villages (see Ostsiedlung). Duke Barnim of Pomerania granted a local government charter to a local community in 1237, separating the Germans from the Slavic majority community settled around the St. Nicholas Church (in the neighborhoods of Chyzin, Uber-Wiken, and Unter-Wiken). Barnim granted the city Magdeburg rights in 1243. In 1277 the city purchased the nearby villages, present-day districts, Krzekowo and Osów. In 1278 Szczecin, along with several other cities, was exempted by King Eric V of Denmark from customs duties for a fair organized in Zealand, Denmark. This is the first case of the city's connections with the Hanseatic League. Around that time the major ethnic group of the city had become German, while the Slavic population decreased.
In 1273 in Szczecin duke of Poznań and future King of Poland Przemysł II married princess Ludgarda, granddaughter of Barnim I, Duke of Pomerania, in order to strengthen the alliance between the two rulers.Kronika wielkopolska, PWN, Warszawa, 1965, p. 297 (in Polish)
From 1295 to 1464 the city was the capital of a splinter eponymous duchy in Pomerania. (Its Dukes were Otto I, Barnim III the Great, Casimir III, Swantibor I, Boguslaw VII, Otto II, Casimir V, Joachim I the Younger, Otto III.) In 1478 it became part (and capital) of the reunited Duchy of Pomerania under duke Bogislaw X, and in 1532 it again became the capital of a splinter eponymous duchy.Genowefa Horoszko, Monety książąt pomorskich z historycznych kolekcji w Muzeum Narodowym w Szczecinie, "Cenne, bezcenne/utracone", Nr 1(74)-4(77), 2013, p. 21 (in Polish)
In the 13th and 14th centuries the town became the main Pomeranian centre of trade in grains, salt and herrings, receiving various trading privileges from their dukes (known as emporium rights). It was granted special rights and trading posts in Denmark, and belonged to the Hanseatic trading cities union. In 1390 trade privileges were granted to Stettin by the Polish king Władysław II Jagiełło who established new trade routes from Poland to the Pomeranian ports. In the 14th and 15th centuries, Stettin conducted several trade wars with the neighboring cities of Gartz, Greifenberg (Gryfino) and Stargard over a monopoly on grains export. The grain supplying area was not only Pomerania but also Brandenburg and Greater Poland – trade routes along the Oder and Warta rivers. The 16th century saw the decline of the city's trading position because of the competition of the nobility, as well as church institutions in the grains exports, a customs war with Frankfurt (Oder), and the fall of the herring market. In the 16th century, it remained an important port for Polish exports of grain, wood, ash, tar and hemp, floated from western Poland down the Warta and Oder rivers. Social and religious riots marked the introduction of the Protestant Reformation in 1534.
Around 1532 minting of coins in the city was halted, to be resumed in 1580 under duke John Frederick. Then were minted the first thalers of the Duchy of Pomerania.
In 1570, the Northern Seven Years' War between Denmark and Sweden was ended in the city by the Treaty of Stettin (1570).
From 1606 to 1618 the city was the residence of Duke Philip II, the greatest patron of the arts among all Pomeranian dukes. He founded a rich collection of ancient and early modern coins at the Ducal Castle. In 1625 the city became again capital of the reunited Duchy of Pomerania under Boguslaw XIV.
By the 1630s the city and surrounding area that hadn't been already German had become completely Germanized.
Under Swedish rule (1630–1720)
During the Thirty Years' War, Stettin refused to accept German imperial armies, instead the Pomeranian dukes allied with Sweden. After the Treaty of Stettin (1630) manifested Swedish occupation, Stettin was fortified by the Swedish Empire. After the death of the last Pomeranian duke, Boguslaw XIV, Stettin was awarded to Sweden with the western part of the duchy in the Peace of Westphalia (1648), but remained part of the Holy Roman Empire. The Swedish-Brandenburgian border was settled in the Treaty of Stettin (1653). The King of Sweden became Duke of Pomerania and as such held a seat in the Imperial Diet of the Holy Roman Empire. The city prospered by trading with Sweden. The inhabitants sympathised with Sweden and fiercely defended the city against an attack by Brandenburg in 1677.
In 1654 the last Pomeranian duke Boguslaw XIV was buried in the Ducal Castle.
Major Prussian and German port (1720–1918)
In 1713, Stettin was occupied by the Kingdom of Prussia; the Prussian Army entered the city as neutrals to watch the ceasefire and refused to leave. In 1720 the city was officially awarded by Sweden to Prussia. In the following years Stettin became the capital of the Prussian Province of Pomerania, and the main port of the Prussian state. From 1740 onwards, the Oder waterway to the Baltic Sea and the new Pomeranian port of Swinemünde (Świnoujście) were constructed.
In 1721, a French commune was founded in the city for the Huguenots. The French were subject to separate French law and had a separate French court, which existed until 1809. In the following years, large groups of Huguenots settled in the city, bringing new developments into the city crafts and factories. The French greatly contributed to the city's economic revival, and were treated with reluctance by the German burghers and city authorities.Skrycki, p. 96 The population increased from 6000 in 1720 to 21,000 in 1816, and 58,000 in 1861.
During the Napoleonic Wars, in 1806 the city surrendered to France without resistance,Skrycki, p. 99 and in 1809 also Polish troops were stationed in the city. In 1813 the city was besieged by combined Prussian-Russian-Swedish forces, and the French retreated in December 1813.Skrycki, p. 100 Afterwards it fell back to Prussia.
The 19th century was an age of large territorial expansion for the city, especially after 1873, when the old fortress was abolished. In 1821, the crafts corporations were abolished, and in steam transport on the Oder began, allowing further development of trade. The port was developing quickly, specialising in exports of agricultural products and coal from the Province of Silesia. Economic development and rapid population growth brought many ethnic Poles from Pomerania and Greater Poland looking for new career opportunities in the local industry. More than 95% of the population consisted of Germans. In 1843, Stettin was connected by the first railway line to the Prussian capital Berlin, and in 1848 by the second railway to Posen (Poznań). New branches of industry were developed, including shipbuilding (at the AG Vulcan Stettin and Oderwerke shipyards) and ironworks using Swedish ores. In 1850–1851, the Polish-language weekly magazine Przyjaciel Chłopów was printed in the city. It was financed by the Prussian authorities and its aim was to promote pro-Prussian and anti-Polish propaganda among the Polish population. Before World War I, there were 3,000 Polish inhabitants in the city,Tadeusz Białecki, "Historia Szczecina" Zakład Narodowy im. Ossolińskich, 1992 Wrocław; pgs. 9, 20-55, 92-95, 258-260, 300-306 including some wealthy industrialists and merchants. Among them was Kazimierz Pruszak, director of the Goleniów (then Gollnow) industrial works, who predicted eventual "return of Szczecin to Poland". The population grew to 236,000 in 1910 and 382,000 in 1939.
During the Franco-Prussian War (1870–1871), the Prussians established a prisoner-of-war camp for around 1,700 French troops in the city, of which 600 died.Skrycki, p. 104 There is a memorial at the site of the former cemetery of the French POWs.
Weimar Republic and Nazi Germany (1918-1945)
In 1918, the city became part of the new Free State of Prussia, part of the Weimar Republic.
After World War I, the economy of Stettin declined again because the seaport was separated from its agricultural supply areas in Posen with the creation of the Second Polish Republic.
In the deeply flawed March 1933 German federal election the Nazi Party received 79,729 votes in the city, i.e. nearly half of the votes cast. The socialists, communists and conservative nationalists have also received noticeable support, receiving 22%, 13% and 11.4% of the votes respectively. In 1933, the Nazis established the Stettin-Bredow concentration camp, one of the early Nazi concentration camps, which however was dissolved in March 1934.
