Rzeczpospolita'' being a traditional name for the ''republic'' when referring to various
Polish states, including the
Polish–Lithuanian Commonwealth (considered to be the First Polish Republic, ''Pierwsza Rzeczpospolita''), and later, the current
Third Polish Republic. In other regionally-used official languages, the state was referred to as: ''Republik Polen'' in
German, ''Польська Республіка'' (
transcription: ''Polʹsʹka Respublika'') in
Ukrainian, ''Польская Рэспубліка'' (
transcription: ''Poĺskaja Respublika'') in
Belarusian, and ''Lenkijos Respublika'', in
Lithuanian.
Between 14 November 1918 and 13 March 1919, the state was referred to in
Polish as ''Republika Polska'', instead of ''Rzeczpospolita Polska''. Both terms mean the ''Republic''; however, ''republika'' is a general term, while ''Rzeczpospolita'' traditionally refers exclusively to Polish states. Additionally, between 8 November 1918 and 16 August 1919, the ''Journal of Laws of the State of Poland'' referred to the country as the ''State of Poland'' (
Polish: ''Państwo Polskie'').

Formation of the Republic

In 1918–1919, over 100
workers' councils sprang up on Polish territories; on 5 November 1918, in
Lublin, the first
Soviet of Delegates was established. On 6 November socialists proclaimed the
Republic of Tarnobrzeg at Tarnobrzeg in Austrian
Galicia. The same day the Socialist,
Ignacy Daszyński, set up a
Provisional People's Government of the Republic of Poland (''Tymczasowy Rząd Ludowy Republiki Polskiej'') in Lublin. On Sunday, 10 November at 7 a.m.,
Józef Piłsudski, newly freed from 16 months in a German prison in
Magdeburg, returned by train to Warsaw. Piłsudski, together with Colonel
Kazimierz Sosnkowski, was greeted at Warsaw's railway station by Regent
Zdzisław Lubomirski and by Colonel
Adam Koc. Next day, due to his popularity and support from most political parties, the Regency Council appointed Piłsudski as Commander in Chief of the Polish Armed Forces. On 14 November, the Council dissolved itself and transferred all its authority to Piłsudski as Chief of State (''
Naczelnik Państwa''). After consultation with Piłsudski, Daszyński's government dissolved itself and a new government formed under
Jędrzej Moraczewski. In 1918, the
Kingdom of Italy

became the first country in Europe to recognise Poland's renewed sovereignty.
Centres of government that formed at that time in
Galicia (formerly Austrian-ruled southern Poland) included the National Council of the
Principality of Cieszyn (established in November 1918), the
Republic of Zakopane and the
Polish Liquidation Committee (28 October). Soon afterward, the
Polish–Ukrainian War broke out in
Lwów (1 November 1918) between forces of the
Military Committee of Ukrainians and the Polish irregular units made up of students known as the
Lwów Eaglets, who were later supported by the Polish Army (see
Battle of Lwów (1918),
Battle of Przemyśl (1918)). Meanwhile, in western Poland, another war of national liberation began under the banner of the
Greater Poland uprising (1918–1919). In January 1919,
Czechoslovak forces attacked Polish units in the area of Trans-Olza (see
Polish–Czechoslovak War). Soon afterwards, the
Polish–Lithuanian War (ca 1919–1920) began, and, in August 1919, Polish-speaking residents of
Upper Silesia initiated a series of three
Silesian Uprisings. The most critical military conflict of that period, however, the
Polish–Soviet War (1919-1921), ended in a decisive Polish victory.
Politics and government

parliamentary democracy from 1919 (see
Small Constitution of 1919) to 1926, with the
President having limited powers. The

The major political parties at this time were the
Polish Socialist Party,
National Democrats, various
Peasant Parties,
Christian Democrats, and political groups of ethnic minorities (German:
German Social Democratic Party of Poland, Jewish:
General Jewish Labour Bund in Poland,
United Jewish Socialist Workers Party, and Ukrainian:
Ukrainian National Democratic Alliance). Frequently changing governments (see
1919 Polish legislative election,
1922 Polish legislative election) and other negative publicity the politicians received (such as accusations of corruption or the
1919 Polish coup attempt), made them increasingly unpopular. Major politicians at this time, in addition to General Piłsudski, included peasant activist
Wincenty Witos (Prime Minister three times) and right-wing leader
Roman Dmowski. Ethnic minorities were represented in the ''Sejm''; e.g. in 1928 – 1930 there was the Ukrainian-Belarusian Club, with 26 Ukrainian and 4 Belarusian members.
After the Polish–Soviet War,
Marshal Piłsudski led an intentionally modest life, writing historical books for a living. After he took power through a
military coup in May 1926, he emphasised that he wanted to heal Polish society and politics of excessive partisan politics. His regime, accordingly, was called ''
Sanacja'' in Polish. The
1928 parliamentary elections were still considered free and fair, although the pro-Piłsudski
Nonpartisan Bloc for Cooperation with the Government won them. The following three parliamentary elections (in

Military

Interwar Poland had a large army of 270,000 soldiers on active duty: in 37 infantry divisions, 11 cavalry brigades, and two armored brigades, plus artillery units. Another 700,000 men served in the reserves. At the outbreak of the war, the Polish Army was able to put in the field almost one million soldiers, 4,300 guns, around 1,000 armored vehicles including in between 200 and 300 tanks (the majority of the armored vehicles were outclassed
tankettes) and 745 aircraft (however, only around 450 of them were bombers and fighters available to fight as of 1 September 1939).

Economy

After regaining its independence, Poland was faced with major economic difficulties. In addition to the devastation brought by the First World War, the exploitation of the Polish economy by the German and Russian occupying powers, and the sabotage performed by retreating armies, the new republic was faced with the task of economically unifying disparate economic regions, which had previously been part of different countries and different empires.
Within the borders of the Republic were the remnants of three different economic systems, with five different currencies (the
German mark, the
Imperial Russian rouble, the
Austrian krone, the
Polish marka and the
Ostrubel)
[ and with little or no direct infrastructural links. The situation was so bad that neighbouring industrial centres, as well as major cities, lacked direct railway links because they had been parts of different jurisdictions and different empires. For example, there was no direct railway connection between Warsaw and ]Kraków

In addition to this was the massive destruction left after both the First World War and the Polish–Soviet War. There was also a great economic disparity between the eastern (commonly called ''Poland B'') and western (called ''Poland A'') parts of the country, with the western half, especially areas that had belonged to Prussia and the German Empire

was the mass economic development plans of the new government (see Four Year Plan) under economist Eugeniusz Kwiatkowski, which oversaw the building of three key infrastructural elements. The first was the establishment of the Gdynia seaport, which allowed Poland to completely bypass Gdańsk (which was under heavy German pressure to boycott Polish coal exports). The second was construction of the 500-kilometre rail connection between Upper Silesia and Gdynia, called the Polish Coal Trunk-Line, which served freight trains with coal. The third was the creation of a central industrial district named COP – '' Centralny Okręg Przemysłowy'' ( English: Central Industrial Region). Unfortunately, these developments were interrupted and largely destroyed by the German and Soviet invasion and the start of the Second World War. Other achievements of interbellum Poland included Stalowa Wola (a brand new city, built in a forest around a steel mill), Mościce (now a district of Tarnów, with a large nitrate factory), and the creation of the central bank Bank Polski SA. There were several trade fairs, with the most popular being Poznań International Fair, Lwów's '' Targi Wschodnie'', and Wilno's '' Targi Północne''. Polish Radio had ten stations (see Radio stations in interwar Poland), with the eleventh one planned to be opened in the autumn of 1939. Furthermore, in 1935, Polish engineers began working on TV services. By early 1939, experts of the Polish Radio built four TV sets. The first movie broadcast by experimental Polish TV was '' Barbara Radziwiłłówna'', and by 1940, a regular TV service was scheduled to begin operation.
Interbellum Poland was also a country with numerous social problems. Unemployment was high, and poverty in the countryside was widespread, which resulted in several cases of social unrest, such as the 1923 Kraków riot, and 1937 peasant strike in Poland. There were conflicts with national minorities, such as the Pacification of Ukrainians in Eastern Galicia (1930), relations with Polish neighbours were sometimes complicated (see Soviet raid on Stołpce, Polish–Czechoslovak border conflicts, and the 1938 Polish ultimatum to Lithuania). On top of this, there were natural disasters, such as the 1934 flood in Poland.
Major industrial centres
Interbellum Poland was unofficially divided into two parts – better developed "Poland A" in the west, and underdeveloped "Poland B" in the east. Polish industry was concentrated in the west, mostly in Polish Upper Silesia, and the adjacent Lesser Poland's province of Zagłębie Dąbrowskie, where the bulk of coal mines and steel plants was located.

( H. Cegielski – Poznań), Kraków and Warsaw ( Ursus Factory). Further east, in Kresy, industrial centres included two major cities of the region – Lwów and Wilno ( Elektrit).
Besides coal mining, Poland also had deposits of oil in Borysław, Drohobycz, Jasło and Gorlice (see Polmin), potassium salt ( TESP), and basalt ( Janowa Dolina). Apart from already-existing industrial areas, in the mid-1930s an ambitious, state-sponsored project called the Central Industrial Region was started under Minister Eugeniusz Kwiatkowski. One of the characteristic features of the Polish economy in the interbellum was the gradual nationalisation of major plants. This was the case for the Ursus Factory (see Państwowe Zakłady Inżynieryjne) and several steelworks, such as ''Huta Pokój'' in Ruda Śląska – Nowy Bytom, ''Huta Królewska'' in Chorzów – Królewska Huta, ''Huta Laura'' in Siemianowice Śląskie, as well as ''Scheibler and Grohman Works'' in Łódź.
Transport
According to the 1939 ''Statistical Yearbook of Poland'', the total length of the railways in Poland (as of 31 December 1937) was . Rail density was per . Railways were very dense in the western part of the country, while in the east, especially Polesie, rail was non-existent in some counties. During the interbellum period, the Polish Government constructed several new lines, mainly in the central part of the country (see also Polish State Railroads Summer 1939). Construction of the extensive Warszawa Główna railway station was never finished due to the war, while Polish railways were famous for their punctuality (see Luxtorpeda, Strzała Bałtyku, Latający Wilnianin).
In the interbellum, the road network of Poland was dense, but the quality of the roads was very poor – only 7% of all roads were paved and ready for automobile use, and none of the major cities were connected with each other by a good-quality highway. In 1939 the Poles built only one highway: 28 km of straight concrete road connecting the villages of Warlubie and Osiek (mid-northern Poland). It was designed by Italian engineer Piero Puricelli.
In the mid-1930s, Poland had of roads, but only 58,000 had a hard surface (gravel, cobblestone or sett), and 2,500 were modern, with an asphalt or concrete surface. In different parts of the country, there were sections of paved roads, which suddenly ended, and were followed by dirt roads. The poor condition of the roads was the result of both long-lasting foreign dominance and inadequate funding. On 29 January 1931, the Polish Parliament created the State Road Fund, the purpose of which was to collect money for the construction and conservation of roads. The government drafted a 10-year plan, with road priorities: a highway from Wilno, through Warsaw and Kraków, to Zakopane (called Marshal Piłsudski Highway), asphalt highways from Warsaw to Poznań and Łódź, as well as a Warsaw ring road. However, the plan turned out to be too ambitious, with insufficient money in the national budget to pay for it. In January 1938, the Polish Road Congress estimated that Poland would need to spend three times as much money on roads to keep up with Western Europe

Statistically, the majority of citizens lived in the countryside (75% in 1921). Farmers made up 65% of the population. In 1929, agricultural production made up 65% of Poland's GNP.

, Upper Silesia and Pomerelia, farming and crops were on a Western European level. The situation was much worse in parts of Congress Poland, the Eastern Borderlands, and what was formerly Galicia, where agriculture was quite backward and primitive, with a large number of small farms, unable to succeed in either the domestic or international market. Another problem was the overpopulation of the countryside, which resulted in chronic unemployment. Living conditions were so bad in several eastern regions, such as the counties inhabited by the Hutsul

minority, that there was permanent starvation. Farmers rebelled against the government (see: 1937 peasant strike in Poland), and the situation began to change in the late 1930s, due to the construction of several factories for the Central Industrial Region, which gave employment to thousands of rural and small town residents.
German trade
Beginning in June 1925, there was a customs' war, with the revanchist Weimar Republic imposing a trade embargo against Poland for nearly a decade; it involved tariffs and broad economic restrictions. After 1933 the trade war ended. The new agreements regulated and promoted trade. Germany became Poland's largest trading partner, followed by Britain. In October 1938, Germany granted a credit of 60,000,000 RM to Poland (120,000,000 ''zloty'', or £4,800,000) which was never realised, due to the outbreak of war. Germany would deliver factory equipment and machinery in return for Polish timber and agricultural produce. This new trade was to be ''in addition'' to the existing German-Polish trade agreements.[Wojna celna (German–Polish customs' war)](_blank)

Education and culture
In 1919, the Polish government introduced compulsory education for all children aged 7 to 14, in an effort to limit illiteracy, which was widespread, especially in the former Russian Partition and the Austrian Partition of eastern Poland. In 1921, one-third of citizens of Poland remained illiterate (38% in the countryside). The process was slow, but by 1931 the illiteracy level had dropped to 23% overall (27% in the countryside) and further down to 18% in 1937. By 1939, over 90% of children attended school.[ Norman Davies (2005), ''God's Playground A History of Poland: Volume II: 1795 to the Present''. Oxford University Press, p. 175. .] In 1932, Janusz Jędrzejewicz, the Minister for Religion and Education, carried out a major reform which introduced two main levels of education: ''common school'' (''szkoła powszechna''), with three levels – 4 grades + 2 grades + 1 grade; and ''middle school'' (''szkoła średnia''), with two levels – 4 grades of comprehensive middle school and 2 grades of specified high school (classical, humanistic, natural and mathematical). A graduate of middle school received a ''small matura'', while a graduate of high school received a ''big matura'', which enabled them to seek university-level education.
Before 1918, Poland had three universities: Jagiellonian University, the University of Warsaw and Lwów University. The Catholic University of Lublin was established in 1918; Adam Mickiewicz University, Poznań, in 1919; and finally, in 1922, after the annexation of the Republic of Central Lithuania, Wilno University became the Republic's sixth university. There were also three technical colleges: the Warsaw University of Technology, Lwów Polytechnic and the AGH University of Science and Technology in Kraków, established in 1919. Warsaw University of Life Sciences was an agricultural institute. By 1939, there were around 50,000 students enrolled in further education. 28% of students at universities were women, which was the second highest share in Europe.
Polish science in the interbellum was renowned for its mathematicians gathered around the Lwów School of Mathematics, the Kraków School of Mathematics, as well as the Warsaw School of Mathematics. There were world-class philosophers in the Lwów–Warsaw school of logic and philosophy.[ ''Also in:'' ] Florian Znaniecki founded Polish sociological studies. Rudolf Weigl invented a vaccine against typhus. Bronisław Malinowski counted among the most important anthropologists of the 20th century.
In Polish literature, the 1920s were marked by the domination of poetry. Polish poets were divided into two groups – the Skamanderites ( Jan Lechoń, Julian Tuwim, Antoni Słonimski and Jarosław Iwaszkiewicz) and the Futurists ( Anatol Stern, Bruno Jasieński, Aleksander Wat, Julian Przyboś). Apart from well-established novelists ( Stefan Żeromski, Władysław Reymont), new names appeared in the interbellum – Zofia Nałkowska, Maria Dąbrowska, Jarosław Iwaszkiewicz, Jan Parandowski, Bruno Schultz, Stanisław Ignacy Witkiewicz, Witold Gombrowicz. Among other notable artists there were sculptor Xawery Dunikowski, painters Julian Fałat, Wojciech Kossak and Jacek Malczewski, composers Karol Szymanowski, Feliks Nowowiejski, and Artur Rubinstein, singer Jan Kiepura.
Theatre was immensely popular in the interbellum, with three main centres in the cities of Warsaw, Wilno and Lwów. Altogether, there were 103 theatres in Poland and a number of other theatrical institutions (including 100 folk theatres). In 1936, different shows were seen by 5 million people, and main figures of Polish theatre of the time were Juliusz Osterwa, Stefan Jaracz, and Leon Schiller. Also, before the outbreak of the war, there were approximately one million radios (see Radio stations in interwar Poland).
Administrative divisions
The administrative division of the Second Republic was based on a three-tier system, referring to the administrative division of the Polish-Lithuanian Commonwealth. On the lowest rung were the '' gminy'', local town and village governments akin to districts or parishes. These were then grouped together into ''y'' (akin to counties), which, in turn, were grouped as ''województwa'' (voivodeship

s, akin to provinces). This administrative system passed into the modern Third Polish Republic.
Demographics
Historically, Poland was almost always a multiethnic country. This was especially true for the Second Republic, when independence was once again achieved in the wake of the First World War
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to ...
and the subsequent Polish–Soviet War, the latter war being officially ended by the Peace of Riga. The census of 1921 shows 30.8% of the population consisted of ethnic minorities, compared with a share of 1.6% (solely identifying with a non-Polish ethnic group) or 3.8% (including those identifying with both the Polish ethnicity and with another ethnic group) in 2011. The first spontaneous flight of about 500,000 Poles from the Soviet Union occurred during the reconstitution of sovereign Poland. In the second wave, between November 1919 and June 1924, some 1,200,000 people left the territory of the USSR for Poland. It is estimated that some 460,000 of them spoke Polish as the first language. According to the 1931 Polish Census: 69% of the population was Polish, 14% were Ukrainian, around 10% Jewish, 3% Belarusian, 2% German and 3% other, including Lithuanian, Czech, Armenian, Russian, and Romani. The situation of minorities was a complex subject and changed during the period.
Poland was also a nation of many religions. In 1921, 16,057,229 Poles (approx. 62.5%) were Roman (Latin) Catholics, 3,031,057 citizens of Poland (approx. 11.8%) were Eastern Rite Catholics (mostly Ukrainian Greek Catholics and Armenian Rite Catholics), 2,815,817 (approx. 10.95%) were Orthodox, 2,771,949 (approx. 10.8%) were Jewish, and 940,232 (approx. 3.7%) were Protestants (mostly Lutheran

).
By 1931, Poland had the second largest Jewish population in the world, with one-fifth of all the world's Jews residing within its borders (approx. 3,136,000). The urban population of interbellum Poland was rising steadily; in 1921, only 24% of Poles lived in the cities, in the late 1930s, that proportion grew to 30%. In more than a decade, the population of Warsaw grew by 200,000, Łódź by 150,000, and Poznań – by 100,000. This was due not only to internal migration, but also to an extremely high birth rate.

Jews
From the 1920s, the Polish government excluded Jews from receiving government bank loans, public sector employment, and obtaining business licenses. From the 1930s, measures were taken against Jewish shops, Jewish export firms, '' Shechita'' as well as limitations being placed on Jewish admission to the medical and legal professions, Jews in business associations and the enrollment of Jews into universities. The political movement National Democracy (''Endecja'', from the abbreviation "ND") often organised anti-Jewish business boycotts. Following the death of Marshal Józef Piłsudski in 1935, the ''Endecja'' intensified their efforts, which triggered violence in extreme cases in smaller towns across the country. In 1937, the National Democracy movement passed resolutions that "its main aim and duty must be to remove the Jews from all spheres of social, economic, and cultural life in Poland". The government in response organised the Camp of National Unity (OZON), which in 1938 took control of the ''Sejm'' and subsequently drafted anti-Semitic legislation similar to the Anti-Jewish laws in Germany, Hungary, and Romania. OZON advocated mass emigration of Jews from Poland, numerus clausus (see also Ghetto benches), and other limitations on Jewish rights. According to William W. Hagen, by 1939, prior to the war, Polish Jews were threatened with conditions similar to those in Nazi Germany.

The warmest yearly average temperature was in Kraków among major cities of the Second Polish Republic, at in 1938; and the coldest in Wilno ( in 1938). Extreme geographical points of Poland included Przeświata River in Somino to the north (located in the Braslaw county of the Wilno Voivodeship); Manczin River to the south (located in the Kosów county of the Stanisławów Voivodeship); Spasibiorki near railway to Połock to the east (located in the Dzisna county of the Wilno Voivodeship); and Mukocinek near Warta River and Meszyn Lake to the west (located in the Międzychód county of the Poznań Voivodeship).
Waters
Almost 75% of the territory of interbellum Poland was drained northward into the Baltic Sea by the Vistula (total area of drainage basin

Polish war plans ( Plan West and Plan East) failed as soon as Germany invaded in 1939. The Polish losses in combat against Germans (killed and missing in action) amounted to ca. 70,000 men. Some 420,000 of them were taken prisoners. Losses against the Red Army (which invaded Poland on 17 September) added up to 6,000 to 7,000 of casualties and MIA, 250,000 were taken prisoners. Although the Polish Army – considering the inactivity of the Allies – was in an unfavourable position – it managed to inflict serious losses to the enemies: 20,000 German soldiers were killed or MIA, 674 tanks and 319 armored vehicles destroyed or badly damaged, 230 aircraft shot down; the Red Army lost (killed and MIA) about 2,500 soldiers, 150 combat vehicles and 20 aircraft. The Soviet invasion of Poland, and lack of promised aid from the Western Allies, contributed to the Polish forces defeat by 6 October 1939.
A popular myth is that Polish cavalry armed with lances charged German tanks during the September 1939 campaign. This often repeated account, first reported by Italian journalists as German propaganda, concerned an action by the Polish 18th Lancer Regiment near Chojnice. This arose from misreporting of a single clash on 1 September 1939 near Krojanty, when two squadrons of the Polish 18th Lancers armed with sabers surprised and wiped out a German infantry formation with a mounted saber charge. Shortly after midnight the 2nd (Motorized) Division was compelled to withdraw by Polish cavalry, before the Poles were caught in the open by German armored cars. The story arose because some German armored cars appeared and gunned down 20 troopers as the cavalry escaped. Even this failed to persuade everyone to reexamine their beliefs—there were some who thought Polish cavalry had been improperly employed in 1939.
Between 1945 and 1990, the Polish government-in-exile operated in London, presenting itself as the only legal and legitimate representative of the Polish nation and challenging the legitimacy of the communist government in Warsaw. In 1990, the last president in exile, Ryszard Kaczorowski, handed the presidential insignia to the newly elected President, Lech Wałęsa
