# History of Pomerania

The history of Pomerania starts shortly before 1000 AD, with ongoing conquests by newly arrived Polan rulers. Before that, the area was recorded nearly 2000 years ago as Germania, and in modern times Pomerania has been split between Germany and Poland. Its name comes from the Old Polish po more, which means "(land) at the sea".
Settlement in the area started by the end of the Vistula Glacial Stage, about 13,000 years ago. Archeological traces have been found of various cultures during the Stone and Bronze Age, of Veneti and Germanic peoples during the Iron Age and, in the Middle Ages, Slavic tribes and Vikings. Starting in the 10th century, Piast Poland on several occasions acquired parts of the region from the south-east, while the Holy Roman Empire and Denmark reached the region in augmenting their territory to the west and north.
In the High Middle Ages, the area became Christian and was ruled by local dukes of the House of Pomerania and the Samborides, at various times vassals of Denmark, the Holy Roman Empire and Poland. From the late 12th century, the Griffin Duchy of Pomerania stayed with the Holy Roman Empire and the Principality of Rügen with Denmark, while Denmark, Brandenburg, Poland and the Teutonic Knights struggled for control in Samboride Pomerelia. The Teutonic Knights succeeded in annexing Pomerelia to their monastic state in the early 14th century. Meanwhile, the Ostsiedlung started to turn Pomerania into a German-settled area; the remaining Wends, who became known as Slovincians and Kashubians, continued to settle within the rural East. In 1325, the line of the princes of Rügen died out, and the principality was inherited by the House of Pomerania, themselves involved in the Brandenburg-Pomeranian conflict about superiority in their often internally divided duchy. In 1466, with the Teutonic Order's defeat, Pomerelia became subject to the Polish Crown as a part of Royal Prussia. While the Duchy of Pomerania adopted the Protestant Reformation in 1534, as part of the Empire by then termed the Holy Roman Empire of the German Nation, Kashubia remained with the Roman Catholic Church. The Thirty Years' and subsequent wars severely ravaged and depopulated most of Pomerania. With the extinction of the Griffin house during the same period, the Duchy of Pomerania was divided between the Swedish Empire and Brandenburg-Prussia in 1648.
Prussia gained the southern parts of Swedish Pomerania in 1720. It gained the remainder of Swedish Pomerania in 1815, when French occupation during the Napoleonic Wars was lifted. The former Brandenburg-Prussian Pomerania and the former Swedish parts were reorganized into the Prussian Province of Pomerania, while Pomerelia in the partitions of Poland was made part of the Province of West Prussia. With Prussia, both provinces joined the newly constituted German Empire in 1871. Following the empire's defeat in World War I, Pomerelia became part of the Second Polish Republic (Polish Corridor) and the Free City of Danzig was created. Germany's Province of Pomerania was expanded in 1938 to include northern parts of the former Province of Posen–West Prussia, and in 1939 the annexed Polish territories became the part of Nazi Germany known as Reichsgau Danzig-West Prussia. The Nazis deported the Pomeranian Jews to a reservation near Lublin and mass-murdered Jews, Poles and Kashubians in Pomerania, planning to eventually exterminate Jews and Poles and Germanise the Kashubians.
After Nazi Germany's defeat in World War II, the German–Polish border was shifted west to the Oder–Neisse line and all of Pomerania was placed under Soviet military control. The area west of the line became part of East Germany, the other areas part of the People's Republic of Poland even though it did not have a sizeable Polish population. The German population of the areas east of the line was expelled, and the area was resettled primarily with Poles (some of whom were themselves expellees from former eastern Poland), and some Ukrainians (who were resettled under Operation Vistula) and Jews. Most of Western Pomerania (Vorpommern) today forms the eastern part of the state of Mecklenburg-Western Pomerania in Federal Republic of Germany, while the Polish part of the region is divided between West Pomeranian Voivodeship and Pomeranian Voivodeship, with their capitals in Szczecin and Gdańsk, respectively. During the late 1980s, the Solidarność and Die Wende movements overthrew the Communist regimes implemented during the post-war era. Since then, Pomerania has been democratically governed.

## Prehistory and antiquity

After the glaciers of the Vistula Glacial Stage retreated from Pomerania during the Allerød oscillation, a warming period that falls within the Early Stone Age, they left a tundra. First humans appeared hunting reindeer in the summer. A climate change in 8000 BC allowed hunters and foragers of the Maglemosian culture, and from 6000 BC of the Ertebølle-Ellerbek culture, to continuously inhabit the area. These people became influenced by farmers of the Linear Pottery culture who settled in southern Pomerania. The hunters of the Ertebølle-Ellerbek culture became farmers of the Funnelbeaker culture in 3000 BC. The Havelland culture dominated in the Uckermark from 2500 to 2000 BC. In 2400 BC, the Corded Ware culture reached Pomerania and introduced the domestic horse. Both Linear Pottery and Corded Ware culture have been associated with Indo-Europeans. Except for Western Pomerania, the Funnelbeaker culture was replaced by the Globular Amphora culture a thousand years later.
During the Bronze Age, Western Pomerania was part of the Nordic Bronze Age cultures, while east of the Oder the Lusatian culture dominated. Throughout the Iron Age, the people of the western Pomeranian areas belonged to the Jastorf culture, while the Lusatian culture of the East was succeeded by the Pomeranian culture, then in 150 BC by the Oxhöft (Oksywie) culture, and at the beginning of the first millennium by the Willenberg (Wielbark) Culture.
While the Jastorf culture is usually associated with Germanic peoples, the ethnic category of the Lusatian culture and its successors is debated. Veneti, Germanic peoples (Goths, Rugians, and Gepids) and possibly Slavs are assumed to have been the bearers of these cultures or parts thereof.
Beginning in the 3rd century, many settlements were abandoned, marking the beginning of the Migration Period in Pomerania. It is assumed that Burgundians, Goths and Gepids with parts of the Rugians left Pomerania during that stage, while some Veneti, Vidivarii and other, Germanic groups remained, and formed the Gustow, Debczyn and late Willenberg cultures, which existed in Pomerania until the 6th century.

### Timeline 10,000 BC–600 AD

* ~10,000 BC (Early Stone Age): first humans hunt in Pomerania after the Ice Age glaciers left (Hamburg culture, a subgroup of the Ahrensburg culture)
* 8000–3000 BC (Middle Stone Age): Maglemosian culture, Ertebølle-Ellerbek culture (Lietzow subgroup)
* 3000–1900 BC (Late Stone Age): Linear Pottery culture, Funnelbeaker culture, Havelland culture, Corded Ware culture, Globular Amphora culture
* 1900–~550 BC (Bronze Age): Nordic Bronze Age (Western Pomerania), Lusatian Culture (Eastern Pomerania)
* ~550 BC–~250 AD (Iron Age): Jastorf culture (Western Pomerania, 550–50 BC), Pomeranian culture (Pomerelia, 650–150 BC), Oxhöft (Oksywie) culture (Pomerelia, 150 BC–1 AD), Willenberg (Wielbark) culture (Pomerelia, 1–250 AD). In part associated with Veneti and Germanic peoples like Suebi, Goths, and Rugians.
* since 200: Migration Period: great parts of the population move south, associated with Burgundians, Goths, Gepids, and parts of the Rugians
* 3rd–6th centuries: Gustow group in Western Pomerania, Dębczyn (Denzin) culture in most of Farther Pomerania, late stage of the Willenberg (Wielbark) culture in Pomerelia and some areas west of it. Associated with Rugian remains and other Germanic tribes, Vistula Veneti, and Vidivarii.

## Early Middle Ages

The southward movement of Germanic tribes and Veneti during the Migration Period had left Pomerania largely depopulated by the 7th century. Between 650 and 850 AD, West Slavic tribes settled in Pomerania. These tribes were collectively known as "Pomeranians" between the Oder and Vistula rivers, or as "Veleti" (later "Liuticians") west of the Oder. A distinct tribe, the Rani, was based on the island of Rügen and the adjacent mainland. In the 8th and 9th centuries, Slavic-Scandinavian emporia were set up along the coastline as powerful centres of craft and trade.
In 936, the Holy Roman Empire set up the Billung and Northern marches in Western Pomerania, divided by the Peene. The Liutician federation, in an uprising of 983, managed to regain independence, but broke apart in the course of the 11th century because of internal conflicts. Meanwhile, Polish Piasts managed to acquire parts of eastern Pomerania during the late 960s, where the Diocese of Kołobrzeg was installed in 1000 AD. The Pomeranians regained independence during the Pomeranian uprising of 1005.
During the first half of the 11th century, the Liuticians participated in the Holy Roman Empire's wars against Piast Poland. The alliance broke off when Poland was defeated, and the Liutician federation broke apart in 1057 during a civil war. The Liutician capital was destroyed by the Germans in 1068/69, making way for the subsequent eastward expansion of their western neighbour, the Obodrite state. In 1093, the Luticians, Pomeranians and Rani had to pay tribute to Obodrite prince Henry.

### Timeline 600–1100

* ~650–~850: Slavic peoples appear and differentiate into several tribes grouped as Polabian Veleti (later Liuticians, Lutizians) in the West and Pomeranians in the East, resettling the regions left by the Germanic tribes

## High Middle Ages

In the early 12th century, Obodrite, Polish, Saxon, and Danish conquests resulted in vassalage and Christianization of the formerly pagan and independent Pomeranian tribes. Local dynasties ruled the Principality of Rügen (House of Wizlaw), the Duchy of Pomerania (House of Pomerania), the Lands of Schlawe and Stolp (Ratiboride branch of the House of Pomerania), and the duchies in Pomerelia (Samborides). Monasteries were founded at Grobe, Kolbatz, Gramzow, and Belbuck which supported Pomerania's Christianization and advanced German settlements.
The dukes of Pomerania expanded their realm into Circipania and Uckermark to the Southwest, and competed with the Margraviate of Brandenburg for territory and formal overlordship over their duchies. Pomerania-Demmin lost most of her territory and was integrated into Pomerania-Stettin in the mid-13th century. When the Ratiborides died out in 1223, competition arose for the Lands of Schlawe and Stolp, which changed hands numerous times.
Throughout the High Middle Ages, a large influx of German settlers and the introduction of German law, custom, and Low German language turned the area west of the Oder into a German one (Ostsiedlung). The Wends, who during the Early Middle Ages had belonged to the Slavic Rani, Lutician and Pomeranian tribes, were assimilated by the German Pomeranians. To the east of the Oder this development occurred later; in the area from Stettin eastward, the number of German settlers in the 12th century was still insignificant. The Kashubians descendants of Slavic Pomeranians, dominated many rural areas in Pomerelia.
The conversion of Pomerania to Christianity was achieved primarily by the missionary efforts of Absalon and Otto von Bamberg, by the foundation of numerous monasteries, and by the assimilatory power of the Christian settlers. A Pomeranian diocese was set up in Wolin, the see was later moved to Cammin.

## Late Middle Ages

The towns of the Hanseatic League were acting as quasi autonomous political and military entities. The Duchy of Pomerania gained the Principality of Rügen after two wars with Mecklenburg, the Lands of Schlawe and Stolp and the Lauenburg and Bütow Land. Pomerelia was integrated into the Monastic state of the Teutonic Knights after the Teutonic takeover of Danzig in 1308, and became a part of Royal Prussia in 1466.
The Duchy of Pomerania was internally fragmented into Pomerania-Wolgast, -Stettin, -Barth, and -Stolp. The dukes were in continuous warfare with the Margraviate of Brandenburg due to Uckermark and Neumark border disputes and disputes over formal overlordship of Pomerania.
In 1478, the duchy was reunited under the rule of Bogislaw X, when most of the other dukes had died of the plague.

## Early Modern Age

Throughout this time, Pomerelia was within Royal Prussia, a part of the Polish–Lithuanian Commonwealth with considerable autonomy. In the late 18th century, it became a part of Prussia.
The Duchy of Pomerania was fragmented into Pomerania-Stettin (Farther Pomerania) and Pomerania-Wolgast (Western Pomerania) in 1532, underwent Protestant Reformation in 1534, and was even further fragmented in 1569, while all parts stayed part of the Empire's Upper Saxon Circle. In 1627, the Thirty Years' War reached the duchy. Since the Treaty of Stettin (1630), it was under Swedish control. In the midst of the war, the last duke Bogislaw XIV died without an issue. Garrison, plunder, numerous battles, famine and diseases left two thirds of the population dead and most of the country ravaged. In the Peace of Westphalia of 1648, the Swedish Empire and Brandenburg-Prussia agreed on a partition of the duchy, which came into effect after the Treaty of Stettin (1653). Western Pomerania became Swedish Pomerania, a Swedish dominion, while Farther Pomerania became a Brandenburg-Prussian province.
A series of wars affected Pomerania in the following centuries. As a consequence, most of the formerly free peasants became serfs of the nobles. Brandenburg-Prussia was able to integrate southern Swedish Pomerania into her Pomeranian province during the Great Northern War, which was confirmed in the Treaty of Stockholm in 1720. In the 18th century, Prussia rebuild and colonised her war-torn Pomeranian province.

## Modern Age

From the Napoleonic Wars to World War I, Pomerania was administered by the Kingdom of Prussia as the Province of Pomerania (Western and Farther Pomerania) and West Prussia (Pomerelia).
The Province of Pomerania was created from the Province of Pomerania (1653–1815) (Farther Pomerania and southern Vorpommern) and Swedish Pomerania (northern Vorpommern), and the districts of Schivelbein and Dramburg, formerly belonging to the Neumark. While in the Kingdom of Prussia, the province was heavily influenced by the reforms of Karl August von Hardenberg and Otto von Bismarck. The Industrial Revolution had an impact primarily on the Stettin area and the infrastructure, while most of the province retained a rural and agricultural character. Since 1850, the net migration rate was negative, Pomeranians emigrated primarily to Berlin, the West German industrial regions and overseas. Also, more than 100,000 Kashubian Poles emigrated from Pomerania between 1855 and 1900, for economic and social reasons, in what is called the Kashubian diaspora. In areas where ethnically Polish population lived along with ethnic Germans a virtual apartheid existed (in Prussian Pomerania this was mostly the Lauenburg and Bütow Land), with bans on Kashubian or Polish language and religious discrimination, besides attempts to colonize areas of prevailingly ethnically Polish population with ethnic Germans the Prussian Settlement Commission, established in 1886 and restricted to act in Posen and West Prussia provinces only, parcelled acquired noble latifundia into 21,727 homesteads of an average of 13 to 15 hectares, introducing 154,000 ethnic German colonists before World War I, which were all outside of Prussian Pomerania, but are also located in areas today denominated as Pomerania in Polish geography. This was surpassed after 1892 by efforts of new private initiatives by minority of ethnically Polish Germans, but a majority in wide parts of Posen and West Prussia province, who founded the Prussian banks Bank Ziemski, Bank Społek Zarobkowych (cooperative central clearing bank) and land acquisition cooperatives (spółki ziemskie) which collected private funds and succeeded to buy more latifundia from defaulted owners and settle more ethnically Polish Germans as farmers on the parcelled land than their governmentally funded counter-party. A big success of the Prussian activists for the Polish nation.
After the First World War, under the terms of the Treaty of Versailles, the Pomeranian Voivodeship of the Second Polish Republic was established from the bulk of West Prussia. Poland became a democracy and introduced the women's right to vote in 1918.
The German minority in the newly created Polish Republic moved to Germany in large numbers, mostly of their own free will and due to their economic situation. For use as a harbor within the Polish Corridor, Poland built a large Baltic port at the site of the former village Gdynia. Also under the terms of the Treaty of Versailles, the Danzig (Gdańsk) area became the Free City of Danzig, a city-state under League of Nations protection.
After the Kaiser's abdication, democracy and the women's right to vote were introduced to the Weimar Republic and through it to the Free State of Prussia and the Province of Pomerania of which it was a part. The economic situation worsened due to the consequences of World War I and the worldwide recession. As in the Kingdom of Prussia before, Pomerania was a stronghold of the nationalistic and anti-Semitic German National People's Party. Between 1920 and 1932, the government of the state of Prussia was led by the Social Democrats, with Otto Braun Prussian minister-president almost continuously during this time.

## Nazi era

In 1933, the Province of Pomerania, like all of Germany, came under control of the Nazi regime. During the following years, the Nazis led by Gauleiter Franz Schwede-Coburg manifested their power by Gleichschaltung and repression of their opponents. Pomerelia then formed the Polish Corridor of the Second Polish Republic. Concerning Pomerania, Nazi diplomacy aimed at incorporation of the Free City of Danzig and a transit route through the corridor, which was rejected by the Polish government.
In 1939, the German Wehrmacht invaded Poland. Inhabitants of the region from all ethnic backgrounds were subject to numerous atrocities by Nazi Germany forces, of which the most affected were Polish and Jewish civilians. Pomerelia was made part of Reichsgau Danzig-West Prussia. The Nazis set up concentration camps, ethnically cleansed Poles and Jews, and systematically exterminated Poles, Roma and the Jews. In Pomerania Albert Forster was directly responsible for extermination of non-Germans in Danzig-West Prussia. He personally believed in the need to engage in genocide of Poles and stated that "We have to exterminate this nation, starting from the cradle", and declared that Poles and Jews were not human.
Around 70 camps were set up for Polish populations in Pomerania where they were subjected to murder, torture and in case of women and girls, rape before executions. Between 10 and 15 September Forster organised a meeting of top Nazi officials in his region and ordered the immediate removal of all "dangerous" Poles, all Jews and Polish clergy In some cases Forster ordered executions himself. On 19 October he reprimanded Nazi officials in the city of Grudziadz for not "spilling enough Polish blood".

## Communist era and recent history

In 1945, Pomerania was taken by the Red Army and Polish Armed Forces in the East during the East Pomeranian Offensive and the Battle of Berlin. After the post-war border changes, the German population that had not yet fled was expelled from what in Poland was propagated to be recovered territory. The area east of the Oder and the Szczecin (former Stettin) area was resettled primarily with Poles, who themselves were expelled from Eastern Poland that was re-attached to the USSR. Most of the German cultural heritage of the region was destroyed. Most of Western Pomerania stayed with Germany and was merged into Mecklenburg.
With the consolidation of Communism in East Germany and Poland, Pomerania was part of the Eastern Bloc. In the 1980s, the Solidarność movement in Gdańsk (Danzig) and the Wende movement in East Germany forced the Communists out of power and led to the establishment of democracy in both the Polish and German part of Pomerania.
