In the Bronze Age the area which became the Neumark fell within the area of the Lusatian culture. In the Iron Age the Jastorf culture operated in this region, identified sometimes with Germanic and sometimes with Celtic tribes.

As its inhabitants moved westward, the region became depopulated during the Migration Period. After AD 500 West Slavic tribes gradually repopulated the area, which became a forest borderland between Pomerania and Greater Poland. According to the Bavarian Geographer's description, the Miloxi inhabited the future Neumark region: they had 47 settlements between the Oder and Poznań.

The region came under the sovereignty of the first Polish state during the 10th-century rule of Mieszko I (died 992) and Bolesław I (ruled 992–1025), Dukes of the Polans.[1] Polish rulers incorporated the future Neumark territory as the Lubusz Land and by the beginning of the 13th century the previously depopulated region had a thinly-spread population of Poles.

Beginning in the 1230s, Low-German–speaking colonists from the Holy Roman Empire began settling north and south of the Warta and Noteć Rivers upon the initiative of Pomeranian and Polish lords; see Ostsiedlung. The lords invited members of the Knights Templar and Knights Hospitaller to establish monasteries, near which settlements began to develop. To fortify the borderland Pomeranian and Polish dukes built castles in the north, around which settlements also grew.

The Ascanian margraves of Brandenburg, starting with Albert the Bear (ruled 1157–70), aspired to extend their dominion east of the Oder. They had gained a foothold east of the river by 1242 and in 1252 the Margraviate of Brandenburg and the Archbishopric of Magdeburg purchased the Lubusz Land. In 1253 they founded Frankfurt an der Oder as a river-crossing and as a staging-point for further expansion eastward.[2] Through land purchases, marriage pacts, and services to Poland's Piast dynasty, the Ascanians extended their territory eastward to the Drawa River and northward to the Parsęta River. For instance, the Polish castellany of Santok, an important base and crossing point over the Warta near its junction with the Noteć, was sought by Pomerania. To relieve himself of the trouble of maintaining the fortress, Duke Przemysł I of Greater Poland granted the castellany to Margrave Conrad as a dowry for his daughter Konstancja. To safeguard the region Margrave John I founded the town of Landsberg an der Warthe (now Gorzów Wielkopolski) in 1257. The Templars sold Soldin to the Ascanians in 1261, and the town began to become a center for the region.

Most of the colonists who settled in Brandenburg's new eastern territory came from Magdeburg or the Altmark ("Old March"). Unlike in the rest of Brandenburg (where the Ascanians settled knights in open villages) the margraves began constructing castles in their land east of the Oder to guard against Poland.[3] The Slavic inhabitants of the region gradually became Germanized. Because the new Terra trans Oderam, or "land across the Oder", formed an extension of the Margraviate of Brandenburg, it became known as the Neumark ("New March") after the middle of the 15th century.

With the extinction of the Ascanian line in 1320, Brandenburg's interest in the Neumark decreased. Neither the margraves of the Wittelsbach (1323–73) nor those of the Luxembourg dynasties concerned themselves with developing their easternmost territory further. The political vacuum allowed Poland to reassert its influence in the area, while robber barons terrorized the populace.

Brandenburg pawned the Neumark to the Teutonic Knights in 1402, and it passed completely under their control in 1429, although the Order neglected the region as well. After the Teutonic Knights' defeat in the Battle of Grunwald (Tannenberg) in 1410, the future Grand Master Michael Küchmeister von Sternberg used the Neumark as a staging ground for an army of German and Hungarian mercenaries which he later used against the forces of King Władysław II Jagiełło of Poland. This allowed the Order to retain much of its territory in the First Peace of Thorn in 1411.[4]

In 1454/1455 the Knights' mismanagement led to their pawning of the Neumark back to Brandenburg, by then led by Elector Frederick II of the Hohenzollern dynasty (Treaties of Cölln and Mewe). After Frederick completed the re-acquisition of Neumark in 1463 for 40,000 guilders, the region belonged to Brandenburg for the following centuries, with the exception of the time between 1535 and 1571. Frederick II wrote for his successors "that the said land, the New Mark, shall belong to German territory and to the worshipful Electorate of the Mark of Brandenburg, with which it was incorporated at the institution of the Electorate, and shall so remain, and shall never pass to those who speak not the German tongue".[5]

After the death of Elector Joachim I Nestor in 1535, Brandenburg's territory west of the Oder (the Kurmark) went to his older son Joachim II Hector, while the Neumark went to his younger son John, who began ruling the Neumark as an independent margraviate and consolidated the land. An enthusiastic supporter of the Protestant Reformation, John succeeded in converting the Neumark to Lutheranism and in confiscating church property. He lived frugally and acquired wealth for his treasury through usury and hiring out mercenary companies.

The division of Brandenburg resulted in trade wars between the brothers, as Crossen and Landsberg competed with the Kurmark's Frankfurt for mercantile primacy. The two margraves eventually compromised — at the economic expense of Stettin. (The brothers also reconciled out of concern for their territories during the Schmalkaldic War of 1546–47.)

In 1548 John's administration moved from Soldin to Küstrin. With the death of both brothers within ten days of each other in 1571, the Neumark became reunited with the Kurmark under Joachim II's son, John George.[3]

In 1618, East Brandenburg became part of Brandenburg-Prussia after the electors' inheritance of the Duchy of Prussia. During the Thirty Years' War (1618–48) both Swedish and Imperial troops plundered, ravaged and burnt the land, while plague epidemics in 1626 and 1631 killed much of the populace. While occupied by Swedish troops the region had to contribute 60,000 thalers and 10,000 Wispel of rye.

Districts in the Neumark as of 1873

After the declaration of the Kingdom of Prussia in 1701, the situation in the Neumark began to improve. King Frederick I initiated new waves of colonization. Many French Huguenots, forced to flee from religious persecution in France, arrived as settlers. The textile industry also began to develop in the Neumark. The Seven Years' War caused the region to regress in its development, as high contributions were exacted from the population for the war effort and the Neumark was the setting for battles such as at Kunersdorf. Under Frederick II, increased land reclamation and economic consolidation resulted from the drainage of the Warta and Notec areas.

The reorganization of Prussia after the territorial changes — resulting from the Congress of Vienna in 1815 — changed the political makeup of the Neumark. The districts of Dramburg and Schivelbein and the northern part of the Arnswalde district with the town of Nörenberg became part of the Province of Pomerania. The Neumark's remaining territory was incorporated into the newly created Frankfurt Region of the Province of Brandenburg.

With the formation of the Prussian-led German Empire in 1871 the Neumark — along with the rest of Brandenburg — became part of a unified German state. In the Weimar Republic's National Assembly of 1 November 1919, the majority of the region voted for the Social Democratic Party of Germany (SPD). The Neumark populace mostly voted for the German National People's Party in the elections for the German Reichstag on 20 May 1928, with a small island of SPD voters. In the Reichstag vote of December 1924 1,900 votes were cast for the Polish People's Party out of a population of 570,000. In 1925 the Neumark had 3,500 Polish-speakers.[6] In the Reichstag vote of 6 November 1932, the Nazi Party won the election in the region.[7]

When the Nazi authorities dissolved the province of Posen-West Prussia in 1938, they expanded the Frankfurt Region to include the districts of Schwerin and of Meseritz, although the New Marcher districts of Arnswalde and of Friedeberg were reassigned to Pomerania. According to the 1939 census, the Neumark had a population of 645,000 residents, including 3,000 non-Germans.[6] The dialect spoken in much of the territory was Neumärkisch, a variation of the East Low German Brandenburgisch dialect.

The Neumark region long featured agriculture and forestry. The medium-sized towns were mostly Ackerbürgerstädte, or farmer-citizen-towns. The textile industry became prominent in the 19th century. With the construction of modern roadways, of the Fernverkehrstraße 1 (an arterial road from Berlin to Königsberg), and of the Prussian Eastern Railway, the Neumark also began to develop industrially. Such development was primarily geared toward agricultural needs and was concentrated near the cities of Landsberg and Küstrin, and the Neumark did not become nearly as industrialized or densely populated as other German areas such as the Ruhr, Saxony, or Upper Silesia.

Near the end of World War II, the Soviet Red Army reached the Neumark at the end of January 1945. Because the Red Army had advanced so quickly, the civilian population of the region suffered greatly from warfare and occupying troops because they had not prepared to flee in time. More than 40,000 New Marchers were killed in action as soldiers.

Under the terms demanded by the Soviet Union in the Potsdam Agreement, the region was put under Polish administration after the Potsdam Conference and eventually became part of Poland. Germans remaining in the region were expelled, and were replaced with Poles, some of whom were from Central Poland, and some of whom had themselves been expelled from the Polish areas annexed by the Soviet Union. A small part of the German population, mostly technicians for the water supply companies, were retained and used for compulsory labour; they were allowed to emigrate to Germany in the 1950s. Older estimates indicated that of the pre-war population of 645,000, only 5,000 of the inhabitants from 1939 remained in the province in 1950.[7][8]

After the regulation of the river Oder in the 18th century the western border of the New March was not adapted to the Oder's new partially more eastern course. Thus the New Marcher villages west of the Oder, now the German-Polish border, remained with post-World War II Germany.

Formerly located within the District of Königsberg in the New March were the villages Adlig Reetz, Alt and Neu Bleyen, Altglietzen, Altreetz, Altwustrow, Bralitz, Croustillier, Drewitz Ausbau (a locality of Bleyen), Gabow, Güstebieser Loose, Hohenwutzen, Karlsbiese, Karlshof, Königlich Reetz (a locality of Oderaue), Küstrin-Kietz, Neuenhagen in the New March, Neuküstrinchen (a locality of Oderaue), Neulietzegöricke, Neuranft, Neurüdnitz, Neutornow, Neuwustrow, Schaumburg in the Oderbruch (a locality of Bleyen), Schiffmühle, Zäckericker Loose and Zelliner Loose (a locality of Letschin). The villages of Aurith and Kunitz-Loose (a locality of Wiesenau) formed part of the Weststernberg district.

The Oder-Neisse line delimiting Germany and Poland split several localities of the region into divided cities:

• Küstrin was separated into German Küstrin-Kietz and Polish Kostrzyn nad Odrą,
• Frankfurt an der Oder was split into German Frankfurt (Oder) and Polish Słubice,
• Guben was divided into German Guben and Polish Gubin,
• Bad Muskau was split into German Bad Muskau and Polish Łęknica,
• Forst was divided into German Forst and Polish Zasieki,
• Görlitz was separated into German Görlitz and Polish Zgorzelec.

To replace the expelled indigenous German population, Soviet authorities re-settled Neumark with Poles and Ukrainians from territories of Poland annexed by the Soviet Union. From 1975 to 1998 the former Neumark territory was divided between the Voivodeships of Gorzów and Zielona Góra with a small section around Chojna in Szczecin Voivodeship. Since the reorganization of Polish voivodeships on 1 January 1999, almost all of the former Neumark region lies within the Lubusz Voivodeship.

During the Polish post-war census of December 1950, data about the pre-war places of residence of the inhabitants as of August 1939 was collected. In case of children born between September 1939 and December 1950, their origin was reported based on the pre-war places of residence of their mothers. Thanks to this data it is possible to reconstruct the pre-war geographical origin of the post-war population. The same area corresponding to 1939 East Brandenburg east of the Oder-Neisse line (which became part of Poland in 1945) was inhabited as of December 1950 by:

Over 95% of the 1950 population were newcomers to the region, with less than 5% residing in German East Brandenburg already back in August 1939 (so called autochthons, who had German citizenship before World War II and were granted Polish citizenship after 1945). The largest group among new inhabitants were Poles expelled from areas of Eastern Poland annexed by the Soviet Union. The second largest group were people from neighbouring pre-war Poznań Voivodeship of Poland (historical Greater Poland region), comprising one-fifth of post-war inhabitants.
