The Kresy Wschodnie, standing for Eastern Borderlands, or simply Kresy (Borderlands; ), was a historical region of the eastern part of the Second Polish Republic. The term was coined during the interwar period (1918–1939). Largely agricultural and extensively multi-ethnic with a Polish minority, it amounted to nearly half of the territory of interwar Poland. Historically situated in the eastern Polish–Lithuanian Commonwealth, following the 18th century foreign partitions, it was divided between the Empires of Russia and Austria-Hungary, and ceded to Poland in 1921 after the Treaty of Riga. As a result of the post-World War II border changes, all of the territory was ceded to the Soviet Union, and today the area of Kresy is divided between Western Ukraine, Western Belarus, and south-eastern Lithuania.

The region gave rise to the Kresy myth, a collection of nostalgic views about the area. After the fall of Communism in Europe and dissolution of the Soviet Union, a major economic conflict emerged about the real estate lost by Poland with the loss of Kresy.

In contemporary studies, the term has been described as colonial and compared to similar other terms such as Russian "okrainy", which in the past was used by Russian imperial authorities to describe its borderlands, which included partitioned Poland.Kolonialne i postkolonialne aspekty polskiego dyskursu kresoznawczego (zarys problematyki)The Russian Okrainy (Oкраины) and the Polish Kresy: Objectivity and HistoriographyKRESY AS AN ELEMENT OF NATIONAL IDENTITY: THE CONTEXT OF BORDERLAND

Extents During the existence of the Polish–Lithuanian Commonwealth, only referred to the borderlands of the Kingdom of Poland and not the Grand Duchy of Lithuania. is also largely co-terminous with the northern areas of the Pale of Settlement, a scheme devised by Catherine II of Russia to limit Jews from settling in the homogenously Christian Orthodox core of the Russian Empire, such as Moscow and Saint Petersburg. The Pale was established after the Second Partition of Poland and lasted until the Russian Revolution in 1917, when the Russian Empire ceased to exist. In the aftermath of the Polish wars against Ukraine, Lithuania and Soviet Russia, the latter of which was ended by the Treaty of Riga, large parts of the Austrian and Russian partitions became part of Poland. As many as 12 million inhabitants lived in the Eastern Borderlands, but ethnic Poles only were a third of that population, with another third being Ukrainian. Most small towns in the Borderlands were shtetls.

Administratively, the Eastern Borderlands territory was composed of Białystok, Lwów, Nowogródek, Polesie, Stanisławów, Tarnopol, Wilno and Wołyń voivodeships (provinces). Today, of these regions, only the western portions of Białystok and Lwów voivodeships remain in Poland (including the eponymous city in Białystok but not Lwów); the remainder of the area is divided between Western Ukraine, Western Belarus, and south-eastern Lithuania, with the major cities of Lviv, Vilnius, and Grodno no longer in Poland. During the Second Polish Republic, the Eastern Borderlands denoted the lands beyond the Curzon Line proposed after World War I in December 1919 by the British Foreign Office as the eastern border of the re-emerging sovereign Polish Republic, after over a century of partition. The interwar period in Kresy was noted by an active policy of Polonization of the local population, which involved enforced usage of Polish language in education as well as settling of the Polish colonists, Osadniks.

In September 1939, after Germany invaded Poland and follow-up invasion by Soviet Union, in accordance with Molotov–Ribbentrop Pact all Eastern Borderlands territories were incorporated into the Soviet republics of Ukraine, Belarus and Lithuania, often by means of terror.Bernd Wegner (1997). From peace to war: Germany, Soviet Russia, and the world, 1939–1941. Berghahn Books. p. 74. . Soviet territorial annexations during World War II were later ratified by the Allies at the Conferences of Tehran, Yalta and Potsdam and most of Poles here were expelled after the end of World War II in Europe. After the dissolution of the Soviet Union in 1991, there was no change to the post-World War II borders. Despite the former provinces of the Eastern Borderlands no longer being part of Poland, a Polish minority remains.

Etymology

The Polish word ("borderlands") is the plural form of the word meaning 'edge'. According to , it is "a medieval borrowing from the German word ", which in the Middle Ages meant ("borderline, delineation or circumscribed territory").Zbigniew Gołąb, "The Origin and Etymology of Old Russian ," International Journal of Slavic Linguistics and Poetics 31/32 (1985, Festschrift H. Birnbaum): 167–174, page 173. Samuel Linde in his Dictionary of the Polish Language gives a different etymology of the term. According to him, meant the borderline between Poland and the Crimean Khanate, in the region of the lower Dnieper. The term appeared for the first time in literature in poems, "" (1854) and "". Pol claimed that Kresy was the line between the Dniester and Dnieper rivers, neighbouring the Tatar borderland. Coincidentally in relation to Jewish settlement in the macro region, the notion of the pale is an archaic English term derived from the Latin word , (which in Polish exists as pal and also means a stake), extended in this instance to mean the area enclosed by a fence or boundary."pale, n.1." OED Online. Oxford University Press, September 2016. Retrieved October 24, 2016. The Pale was the part of medieval Ireland controlled by the English government.

At the beginning of the 20th century, the meaning of the term expanded to include the lands of the former eastern provinces of the Polish–Lithuanian Commonwealth, east of the line. In the Second Polish Republic, equated to historically Polish settled lands to the east of the notional Curzon line. Currently, the term applies to all the eastern lands of the Second Polish Republic that are no longer within the frontiers of modern Poland, together with lands further east, that had been integral to the Commonwealth before 1772, and where Polish communities continue to exist.

History Polish eastern settlements date back to the dawn of Poland as a state. In 1018, King Bolesław I the Brave invaded Kievan Rus' (see Bolesław I's intervention in the Kievan succession crisis, 1018), capturing Kyiv, and annexing the Cherven Cities. In 1340, Red Ruthenia came under Polish control, which intensified defensive Polish settlement and the introduction of Catholicism. After the Union of Lublin 1569, more Polish settlers moved into the eastern borderlands of the vast Polish–Lithuanian Commonwealth. Most of them came from the Polish provinces of Mazovia and Lesser Poland. They had moved gradually eastwards settling in sparsely populated areas, inhabited by earlier inhabitants such as Lithuanians and Ruthenians. Moreover, the indigenous upper classes of Kresy adopted Polish catholicism, culture and language, resulting in their assimilation and Polonization.

The Partitions of Poland The year 1772 marked the first partition of the Commonwealth of the Kingdom of Poland and the Grand Duchy of Lithuania (see Partitions of Poland). By 1795, the whole eastern half of the state had been annexed by the Russian Empire in concert with the Habsburgs and Prussia's Hohenzollerns. The dramatic westward expansion of the Russian Empire through the annexation of Polish-Lithuanian territory substantially increased the new "Russian" Jewish population. Kresy and the superimposed Pale, in the former Polish and Lithuanian territories, had a Jewish population of over five million, and represented the largest community (40%) of the world Jewish population at that time.

From the Polish perspective, the lands came to be called the "Stolen Lands". Even though Poles were a minority in those areas, owing to forced depopulation, the "Stolen Lands" remained an integral part of Polish national identity, with Polish cultural centres and seats of learning in Vilnius University, Jan Kazimierz University and Krzemieniec Lyceum among many others. Since many local educated inhabitants had actively participated in Polish–Lithuanian national insurgencies (November Uprising, January Uprising), the Russian authorities resorted to intensified persecution, confiscations of property and land, penal deportation to Siberia, and the systematic attempt at Russification of Poles and their traditional culture and institutions.

The Pale of Settlement

From the Russian perspective the "Pale of Settlement" included all of Belarus, Lithuania and Moldova, much of present-day Ukraine, parts of eastern Latvia, eastern Poland, and some parts of western Russia, generally corresponding to the macroregion and the modern-day western border of Russia. It extended from the eastern pale, or demarcation line, to the Russian border with the Kingdom of Prussia (later the German Empire) and Austria-Hungary. It also comprised about 20% of the territory of European Russia and largely corresponded to historical lands of the former Polish–Lithuanian Commonwealth, Cossack Hetmanate, and the Ottoman Empire (with Crimean Khanate).

The area included in the Pale, with its large Roman Catholic, Eastern Catholic and Jewish populations, was acquired through a series of military conquests and diplomatic manoeuvres, between 1654 and 1815. While the religious nature of the edicts creating the Pale is clear: conversion to Russian Orthodoxy, the state religion, released individuals from the strictures - historians argue that the motivations for its creation and maintenance were primarily economic and nationalistic in nature.

Economic decline of Kresy

The Russian Empire had abandoned Kresy to decline as a vast rural backwater after the original Polish–Lithuanian landowners had been disposed of in the wake of insurrections and the Abolition of serfdom in Poland in 1864. The devastation of country estates put a halt to large scale economic activity which had depended on agriculture, forestry, brewing and small scale industries.

Paradoxically, the Southern Kresy (present-day Ukraine) was famous for its fertile soil and was known as the "bread basket of Europe". Towards the end of the 19th century, the decline was so acute that trade and food supplies became problematic and large scale emigration from towns and villages began as Jewish communities, in particular, began heading West, to Europe and the United States. By the time of a newly resurgent Polish state, the provinces had been additionally disadvantaged by having the lowest literacy levels in the country, since education had not been compulsory during Russian rule.W dodatku Kresy Wschodnie II Rzeczypospolitej były najbiedniejszym regionem kraju Polska ludność kresowa: rodowód, liczebność, rozmieszczenie Piotr Eberhardt, page 21 Wydawnictwo Naukowe PWN, 1998Historia gospodarcza Polski Andrzej Jezierski, page 269, 2006 The regions had suffered a legacy of decades of neglect and underinvestment so were generally less economically developed than the western parts of interwar Poland.

Between the World Wars

The years 1918–1921 were especially turbulent for , due to the resurgence of the Polish nation-state and the formation of new borders. At that time, Poland had fought three wars to establish its eastern frontier: with Ukraine, Lithuania and Soviet Russia. In all three conflicts, Poland made territorial conquests, and as a result, it seized territories east of the Curzon line that were previously conquered by Russia, in addition to the land formerly part of the Austrian Galicia. The was the most war-devastated area in the whole of interwar Poland. The region later formed the eastern provinces of the Second Polish Republic.
