|History of Poland|
|Prehistory and protohistory|
The history of interwar Poland comprises the period from the re-recreation of the independent Polish state in 1918, until the joint Invasion of Poland by Nazi Germany and the Soviet Union in 1939 at the onset of World War II. The two decades of Poland's sovereignty between the world wars are known as the Interbellum.
Poland re-emerged in November 1918 after more than a century of partitions by Austria-Hungary, the German, and the Russian Empires. Its independence was confirmed by the victorious powers through the Treaty of Versailles of June 1919, and most of the territory won in a series of border wars fought from 1918 to 1921. Poland's frontiers were settled in 1922 and internationally recognized in 1923. The Polish political scene was democratic, but was chaotic until Józef Piłsudski (1867–1935) seized power in May 1926 and democracy ended. The policy of agrarianism led to the redistribution of lands to peasants and the country achieved significant economic growth between 1921 and 1939. A third of the population consisted of minorities—Ukrainians, Jews, Belarusians and Germans—who were either hostile towards the existence of the Polish state because of the lack of privileges or often discriminated against in the case of Ukrainians and Belarusians who faced Polonization. There were treaties that supposedly protected them but the government in Warsaw was not interested in their enforcement.

Formative years (1918-1921)
The independence of Poland had been successfully promoted to the Allies in Paris by Roman Dmowski and Ignacy Paderewski. U.S. President Woodrow Wilson made the independence of Poland a war goal in his Fourteen Points, and this goal was endorsed by the Allies in spring 1918. As part of the Armistice terms imposed on Germany, all German forces had to stand down in Poland and other occupied areas. So as the war ended, the Germans sent Piłsudski, then under arrest, back to Warsaw. On November 11, 1918, he took control from the puppet government the Germans had set up. Ignacy Daszyński headed a short-lived Polish government in Lublin from November 6 but Piłsudski had overwhelming prestige at this point. Daszyński and the other Polish leaders acknowledged him as head of the army and in effect head of what became the Republic of Poland. Germany, now defeated, followed the terms of the Armistice and withdrew its forces. Paderewski became the first prime minister (in early 1919) and Dmowsky headed the largest party.
From its inception the Republic fought a series of wars to secure its boundaries. The nation was rural and poor; the richest areas were in the former German areas in the west. Industrialization came very slowly, and was promoted in the mid-1930s with the development of the Central Industrial District.
Most Polish leaders of that period wanted to create a larger Polish state; one optimal plan, dating back to the Paris Peace Conference, included the incorporation of East Prussia and the German city of Königsberg being placed in a customs union with Poland. At the same time, the exact boundaries of the former Polish-Lithuanian Commonwealth were not desired, though mentioned as an opening gambit by Roman Dmowski. Much of this land had been controlled by the Russian Empire since the Partitions of Poland and its inhabitants were struggling to create their own states (such as Ukraine, Belarus, and the Baltics: Lithuania, Latvia, Estonia). The Polish leadership did not aim to restore the nation to its 17th-century boundaries. Opinions varied among Polish politicians as to how much of the territory a new, Polish-led state should contain and what form it should take. Józef Piłsudski advocated a democratic, Polish-led federation of independent states — while Roman Dmowski leader of the Endecja movement represented by the National Democratic Party, set his mind on a more compact Poland composed of ethnic Polish or 'polonizable' territories.
To the southwest, Poland and Czechoslovakia contested boundary disputes (see: Zaolzie). More ominously, an embittered Germany begrudged any territorial loss to its new eastern neighbour. The December 27, 1918 Great Poland Uprising liberated Greater Poland. The 1919 Treaty of Versailles settled the German-Polish borders in the Baltic region. The port city of Danzig (Polish: Gdańsk), with a majority German population and Polish minority was declared a free city independent of Germany, and became a bone of contention for decades. Allied arbitration divided the ethnically mixed and highly coveted industrial and mining district of Silesia between Germany and Poland, with Poland receiving the smaller in size, but more industrialized eastern section in 1922, after series of three Silesian Uprisings.
The German-Polish borders were so complicated that only close collaboration between the two countries could let the situation persist (1930 km., compared to the 430 km. of the present-day Oder–Neisse line). The unification of the former Prussian provinces lasted for many years. Until 1923, these provinces were ruled by a separate administration.
War with Soviet Russia
Military conflict proved the determinant of Poland's frontiers in the east, a theater rendered chaotic by the repercussions of the Russian revolutions and civil war. Piłsudski envisioned creating a federation with the rest of Ukraine (led by the Polish-friendly government in Kiev he was to help to install) and Lithuania, thus forming a Central and East European federation called "Międzymorze" (literally "between seas"). Lenin, leader of the new communist government of Russia, saw Poland as the bridge over which communism would pass into the labor class of a disorganized postwar Germany. And the issue was further complicated as some of the disputed regions had assumed various economic and political identities since the partition in the late 18th century while some did not have an ethnically Polish majority in the first place they were still viewed by Poles as their historic regions, since they envisioned Poland as a multiethnic state. In the end, the negotiations broke down, sinking Piłsudski's idea of Międzymorze federation; instead, wars like the Polish-Lithuanian War or the Polish-Ukrainian War decided the borders of the region for the next two decades.
The Polish-Soviet war, began in 1919, was the most important of the regional wars. Piłsudski first carried out a major military thrust into Ukraine in 1920 and in May Polish-Ukrainian forces reached Kiev. Just a few weeks later, however, the Polish offensive was met with a Soviet counter-offensive, and Polish forces were forced into a retreat by the Red Army. Poland was driven out of Ukraine and back into the Polish heartland. Most observers at the time marked Poland for extinction and Bolshevization, However at the Battle of Warsaw Piłsudski organized a stunning counterattack that won a famous victory. This "Miracle on the Vistula" became an iconic victory in Polish memory. Piłsudski resumed the offensive, pushing the Red forces east. Eventually both sides, exhausted, signed a compromise peace treaty at Riga in early 1921 that divided the disputed territories of Belarus and Ukraine between the two combatants. These acquisitions were recognized by the international agreement with the Entente. The treaty gave Poland an eastern border well beyond what the peacemakers in Paris had envisioned, and added 4,000,000 Ukrainians, 2,000,000 Jews, and 1,000,000 Belarusians to Poland's minority population.
In Soviet historiography, the Polish-Soviet War was also referred to as "the war against White Poles", with epithet "White Poles" (belopoliaki) alleging the "counter-revolutionary" character of Poland at the time, in an analogy with Russian White Movement.
The Riga arrangement influenced the fate of the entire region for the years to come. Ukrainians and Belarusians found themselves without a country or province of their own, and some Polish speakers also found themselves within the borders of the Soviet Union. The latter experienced forced collectivistion, state terror, suppression of religion, purges, labor camps and famine. The newly formed Second Polish Republic, one third of whose citizens were non-ethnic Poles, engaged in promoting Polish identity, culture and language at the expense of the country's ethnic minorities who felt alienated by the process.
Reborn Poland faced a host of daunting challenges: extensive war damage, a ravaged economy, a population one-third composed of wary national minorities, an economy largely under control of German industrial interests, and a need to reintegrate the three zones that had been forcibly kept apart during the era of partition. Poland's formal political life began in 1921 with adoption of a constitution that designed Poland as a republic modeled after the French Third Republic, vesting most authority in the legislature, the Sejm. This was mainly to prevent Piłsudski from establishing himself as a dictator. A multitude of political parties emerged, of which there were four major and dozens of minor ones. All had very different ideologies and voter bases, and could scarcely agree on any major issue. There had been no serious consideration of re-establishing a monarchy, and although the great Polish noble families continued to have their names mentioned in newspapers, it was mostly in the society pages. The chief parties were the left-wing Polish Peasant Party (PSL) and on the right National Democracy party (ND) led by Dmowski.
The new, inexperienced government faced serious problems; already there was rampant corruption among government officials; a dizzying turnover of cabinets caused confusion and distrust. At a deeper level there was profound disagreement about inclusiveness in the new state. Roman Dmowski envisioned an ethnically-homogeneous Polish nation, and a pro-Western, anti-German path to modernization; he also espoused strong anti-Semitic attitudes, and emphasized that Poland should be a Catholic and hierarchical state. Piłsudski, however, rooted his ideal in notions about the multi-ethnic Polish-Lithuanian Commonwealth. In practice that meant ignoring the minority vote at home and seeking agreements with nearby countries. Universal suffrage gave the minorities a voice, especially when they formed a coalition, the Bloc of National Minorities (BMN) led by the Jews and including the others who together comprised a third of the population and 20% of the vote. However the districts were gerrymandered to minimize minority representation. The BMN helped elect Gabriel Narutowicz as president on the PSL ticket in 1922, but he came under nasty attacks from the right and was assassinated after five days in office. The BMN coalition declined in significance and shut down in 1930 as the different groups cut their own deals with the government on isolated issues.
Coup of 1926
After the constitution was adopted, Piłsudski resigned from office, unhappy with the limited role of the executive branch. But he continued to keep a close eye on political developments. The ineffectiveness of the Sejm led some of his inner circle to suggest that he launch a military coup and regain power; he said no. By 1926 he was persuaded and launched the coup of May 1926, which succeeded with little violence. For the next decade, Piłsudski dominated Polish affairs as strongman of a generally popular centrist regime, although he never held a formal title except for minister of defense. He retained the 1921 constitution, and the noisy, ineffective Sejm continued to operate, but it nearly always gave him what he wanted. Critics of the regime were occasionally arrested, but most were sued for libel. The marshal portrayed himself as a national saviour who was above partisan politics, and gained more popular support by distancing himself from the Polish Socialist Party. In 1935 a new Polish Constitution was adopted, but Piłsudski soon died and his protégé successors drifted toward open authoritarianism. Opposition voices were increasingly harassed or jailed, a situation that was not surprising in view of the regime's growing fears over national security.
In many respects, the Second Republic fell short of the high expectations of 1918. As happened elsewhere in Central Europe, with the exception of Czechoslovakia, the attempt to implant democracy did not succeed. Governments polarized between right- and left-wing factions, neither of which was prepared to honor the actions taken by the other.
Serious difficulties arose in dealing with foreign assets and internal minorities.
The government nationalized foreign-owned assets and operated them because there was insufficient domestic capital to buy them, and because it was easier than determining who should get what. Overall, Poland had a higher degree of state involvement in the economy and less foreign investment than any other nation in eastern Europe. This emphasis on economic centralisation hampered Poland's development. The economy was largely rural, and the worldwide Great Depression that began in 1929 saw hardship in every sector. Worst hit were the peasants whose incomes plunged 50% or more. The government had few solutions except to reduce its own spending as tax revenues fell.
About a third of the total population were members of minorities, including five or six million Ukrainians, over three million Jews, one and a half million Belarusians, and some 800,000 Germans. These minorities were increasingly alienated, complaining that they were marginalized in politics and denied rights Poland had agreed to in treaties. Historian Peter D. Stachura has examined the ethnic issue in interwar Poland and summarizes the consensus of historians, he writes:
- "It is undeniable that the Second Republic did not face any greater challenge than that of devising a policy towards the minorities that would bring harmony and peaceful coexistence rather than bitterness, confrontation and strife. The historiographical verdict is that Poland signally failed to address this question in a satisfactory manner. Indeed, the vast majority of historians have adopted a highly censorious attitude towards the multitude of policies and attitudes which were pursued towards the minorities by the state. Often influenced by Communist, Marxist, Soviet or liberal political and ideological perspectives, they refer unequivocally to 'oppression', 'persecution', 'terror', 'discrimination', even 'murder', as the salient characteristics of an intrinsically chauvinistic Polish approach that was designed to relegate the minorities to the status of second-class citizens. Such a situation, it is argued, meant that Poland failed repeatedly to respect the formal statutory guarantees which were introduced after 1918, notably through the Minorities' Treaty of 1919, the Treaty of Riga (Article VII) in 1921, and the Polish constitutions of 1921 and 1935."
Stachura himself thinks the historians have been too harsh in their negative judgment. He notes that Poland had to contend with "an obstreperous and fundamentally disloyal German minority" that was incited by "fanatical" German nationalists next door. Poles talked of forced assimilation and seizure of industrial assets, but the governments before 1926 were too weak to carry them out. After 1926 Piłsudski had no interest in so doing. The Germans in Poland had above-average incomes, had a full panoply of civic organizations and German-language schools, and were represented in the Sejm. A stalemate resulted. Their status became a major threat after Hitler came to power in Germany in 1933, because "the overwhelming majority of these Germans became ardent Nazis in the 1930s and a 'fifth column' when Poland was attacked in September 1939."
Relations with the much larger Ukrainian minority, who formed 15% or so of the national population and were in the majority in several eastern provinces, were even more strained. The Ukrainians were poor peasants who resented their Polish landlords and the government's policy of polonizing them. The schools after 1924 were bilingual (students had to learn Polish), and government offices were not allowed to use Ukrainian. Some Ukrainians tried sabotage, and the government cracked down with mass arrests; it tolerated Polish arson of Ukrainian community centers. Orthodox churches were closed, especially in Volhynia province. Some men went underground and tried to assassinate Ukrainians who collaborated with the government, as well as top Polish officials. A compromise was reached in 1935 that somewhat quieted the situation, but the Polish Army saw a war with the USSR looming and refused to support the policy.
As the Great Depression worsened in the 1930s, antisemitism began to rise even though Poland was home to over three million Jews (10 per cent of Poland's population), the largest Jewish population in Europe at the time. The impoverished Jewish families relied on their own local charities, which by 1929 had reached unprecedented proportions, providing services such as religion, education, health and other services to the value of 200 million złoty a year, thanks in part to Jewish per capita income among the working Jews more than 40% higher than that of Polish non-Jews.
At the insistence of President Woodrow Wilson, the Paris Peace Conference of 1919 required Poland to sign a treaty on June 28, 1919 that guaranteed minority rights in the new nation. Poland signed under protest as Germany was not required to sign the treaty and the rights of Polish people in Germany were not protected, while Polish requests to Allies that the Polish minority in Germany be given the same level of protection as the German minority in Poland were ignored. As a result of Allies enforcing the treaty on Poland it was received by the public as humiliation. Poland made little effort to enforce the specified rights for Germans, Jews, Ukrainian, and other minorities. Similar treaties were required of most other new countries, except Germany which was the only country relieved from this obligation. However Polish attempts to modify the proposed Versailles Treaty so that Germany would not be able to interfere in internal Polish matters were rejected. The key provisions were to become fundamental laws that overrode any national legal codes or legislation. Poland pledged to assure "full and complete protection of life and liberty to all individuals...without distinction of birth, nationality, language, race, or religion." Freedom of religion was guaranteed to everyone. Most residents were given citizenship, but there was considerable ambiguity on who was covered. The treaty guaranteed basic civil, political, and cultural rights, and granted all citizens equality before the law equal rights of citizenship and employment. Polish was of the national language, but the treaty provided that minority languages could be freely used privately, in commerce, religion, the press, at public meetings, and before all courts. Minorities were to be permitted to establish and control at their own expense private charities, churches, and social institutions, as well as schools, without interference from the government. The government was required to set up German-language public schools in those districts that had been German territory before the war. All education above the primary level was to be conducted exclusively in the national language. Article 12 was the enforcement clause; it gave the Council of the League of Nations responsibility for monitoring and enforcing each treaty. Eventually Polish government signed a bilateral treaty with Nazi Germany that was to protect rights of both nationalities in both countries and renounced the Minorities treaty in September 1934. Despite this, the Polish population in Germany continued to face discrimination and harassment.
Seven out of ten of the people worked on farms as peasants. Polish agriculture suffered from the usual handicaps of Eastern European nations: technological backwardness, low productivity, and lack of capital and access to markets. The former German areas in the west had better rainfall and soil quality and were the most productive, while the former Russian and Austrian areas were below-average. The Polish peasantry believed that it would be so much better if they owned their land and did not pay rents to a landowner. They endorsed agrarianism and called for land redistribution away from large estates to peasants. This was done and also many very small farms were consolidated into viable units. Land reforms were undertaken along ethnic lines. In the west, Germans who had been made foreigners in 1919 quickly lost their land. In the east by contrast, Ukrainian and Belarusian peasants tilled for Polish landowners and no serious moves toward land redistribution were taken. No alternative industrial jobs were developed and underemployment was high in rural areas.
The socialist politician Bolesław Limanowski thought deeply about Agrarianism and worked out an eclectic program that fit Polish conditions. His practical experience as a farm manager combined with socialist, "single-tax," and Slavic communal ideas shaped his worldview. He proposed a form of agrarian socialism with large state farms to counteract the inefficiency of very small holdings. In independent Poland, he advocated expropriation of gentry estates. His observation of peasant individualism convinced him that Poland should combine voluntary collectivism and individual possession of the leased land. His pragmatism left the room even for private peasant ownership, despite his Marxism.
Polish nationalists in the interbellum years could justifiably claim some noteworthy accomplishments: economic advances, the revival of Polish education and culture after decades of official curbs, and, above all, a realization of Polish nationhood. Despite its defects, the Second Republic retained a strong hold on later generations of Poles as a genuinely independent and authentic expression of Polish national aspirations. The minorities shared in the economic revival but were politically marginalized.
Foreign minister Józef Beck was in full charge of foreign policy by 1935 but he had a weak hand. Poland with 35 million people had a large population but a thin industrial base; its war plans focused on the Soviet Union instead of Germany. Poland had long borders with two more powerful dictatorships, Hitler's Germany and Stalin's USSR. Poland was increasingly isolated. Overy says that of all the new states in Europe:
- "Poland was almost certainly the most disliked and her Foreign Minister the most distrusted. Poland's pursuit of an independent line left her bereft of any close friends by the end of 1938…. The Western powers saw Poland as a greedy revisionist power, illiberal, anti-Semitic, pro-German; Beck was a 'menace,' 'arrogant and treacherous.'"
Poland sought to be the leader of an independent bloc of nations between the Soviet Union and Germany that would unite to fend off those powers. However, Poland ran into so many disputes with its smaller neighbors that it was never able to build a bloc. At first, France favored Poland, because France wanted an ally against Germany; if Germany faced a two-front war, it would be less likely to attack France. France was especially helpful at the 1919 Paris conference and in the 1920s when it resisted British efforts to weaken Poland. After 1935, however, France distrusted Beck and lost interest in Eastern Europe and Poland stood increasingly alone. Poland saw the Soviets as the greatest enemy and would never deal with them. Germany was a lesser threat and relations were good with Germany after 1933, as late as early 1939.
In 1925, Berlin formally recognized its post-1918 boundaries in the west with France, but not in the east with Poland. An outraged Poland decided to exclude all German imports from its soil. Germany then did likewise for Polish goods. The ensuing trade war had popular support but proved harmful to the economy. Relations with the Soviet Union remained hostile, but Piłsudski was willing to negotiate, and in 1932 the two countries finally established diplomatic relations. Shortly afterward, Hitler came to power. Rumors circulated to the effect that Piłsudski proposed to France that Poland and France launch a preemptive military strike to overthrow Hitler in 1933. Most historians do not believe this happened, pointing out that Piłsudski's war plans were focused on Russia and he made no preparations for any sort of war with Germany. Furthermore, no one in France reported any such inquiry from Poland. Piłsudski made demands regarding Danzig that Hitler immediately approved; relations between Poland and Nazi Germany became friendly and they signed the German–Polish Non-Aggression Pact in January 1934. At the same time, Czechoslovakia, Romania, and Yugoslavia were allied in the Little Entente with French support. Polish membership there could have provided additional security; however, relations with Prague were unfriendly due to border disputes, so they never reached an agreement.
France was an ally of both Poland and Czechoslovakia and tried repeatedly to get them to resolve their border disputes and become allies, and also collaborate with the Soviet Union. There was no success, not just because of the border issues but also because Prague's willingness to work with Moscow clashed with the firm resolve of Warsaw to keep its distance from Moscow. Czechoslovakian President Edvard Beneš warned that military or even strong political ties with Poland could prove dangerous for Czechoslovakia.
The failure to establish any alliances in Eastern Europe meant the only ally was France; Piłsudski increasingly doubted the value of that alliance. The Locarno Pact, signed in 1926 by the major West European powers with the aim of guaranteeing peace in the region, contained no guarantee of Poland's western border.
The budget for the year 1934-35 allocated 762 million zlotych for the army, about 32% of the total. It provided for an effective strength of 7,905 officers, 37,000 professional soldiers, and 211,110 militia soldiers. Apart from the army, the budget provided 105 million zlotych for police troops consisting of 774 officers and 28,592 men.
By 1939 Poland had a large army, with 283,000 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. A major problem was lack of funds. The limited defense budget allowed minimal mechanization; most weapons were produced in Poland, but the production rate was low (7TP tank is a prime example), and foreign exchange was scarce. The fact that Poland was halfway through the rearming process that was to end in 1942 did not help. Ten divisions were never mobilized. The cancellation of the mobilization, under the pressure from France and Great Britain, and restarting the mobilization less than a week later created confusion. Moreover, not only did the German military and civilian volunteers commit war crimes against the ethnic Poles and Polish Jews, they spread rumors of massive ethnic cleansing which lead thousands of people to flee the German advance and made military maneuver difficult.
Poland did have PZL, the state aviation company that made good planes. In 1931 it developed the PZL P.11, the most advanced fighter in the world of the early 1930s. In the mid-1930s its successor the P-24 was even better armed and faster, but Poland exported it to earn currency, forcing the use of semi-obsolete PZL P.11 and a couple dozen old PZL P.7 fighters. They were no match against the German Messerschmitt 109 which could fly higher, was better armed, and flew 100 kph faster. In spite of the shortcomings, at least 110 victories were credited to the P.11 for the loss of about 30 of their own. The PZL.37 Łoś was an excellent twin-engine medium bomber; Poland had 36 ready-to-fight when the war started. In 1939 Poland had 390 combat planes that were mostly obsolescent. Germany had 2800 new fighter planes plus bombers and transports.
The Poles, in spite of desperate situation, managed to win two battles against the invading Soviets, including one where the Soviet infantry was charging the Polish positions marching shoulder to shoulder, making them into an extremely easy target to the machine guns, and some of the Soviet POW's switched sides to the Polish.
Poles beat the early diplomatic version of Enigma cipher and transferred the results to France and United Kingdom.
In spite of its shortcomings, the Polish military can easily be ranked in top 10 strongest national militaries as of 1939; not because the Polish military was so great, but because other national military forces were so weak and backward. Zaloga and Madej point out, in "The Polish Campaign 1939" that Poland had one of the largest tank forces on Earth, as of 1939 bigger than the task force of the USA.
The relative strength of the Polish armed forces and the fear of the Polish military might be shown by Lithuania (1938 Polish ultimatum to Lithuania) made the Polish government's propaganda believable to the public. The Polish government had no choice, but to claim that an attack either by the Germans or by the Soviets would have been successfully repealed. The Polish government could not afford a capitulation of the Polish public because of the industrialization projects such as Central Industrial Region (Poland), nearly finished by early 1939, and the projects that were to follow it.
Foreign policy 1935–39
After the death of Piłsudski in May 1935, policies in Poland were set by five senior officials, including President Ignacy Mościcki; Vice-President Eugeniusz Kwiatkowski; the Premier, Felicjan Sławoj Składkowski; and Marshal Edward Smigly-Rydz, the Commander-in-Chief of the army. Foreign-policy was the exclusive domain of the Foreign Minister, Colonel Józef Beck. Elections were held but there was no democracy and the Sejm was merely a rubber stamp. Watt notes that these men had emerged victorious from their struggles for independence and had never known conquest. "Courage, flair, heroism, devouring ambition, all these they had in abundance; realism and worst-case analysis, let alone defeatism or appeasement, were alien to them entirely."
Poland's dream of leading a bloc of neutral nations in Eastern Europe collapsed after 1933 with the advent of Hitler's openly expansionist Nazi regime in Germany and the obvious warning of France's desire to resist Germany's expansion. Piłsudski retained the French connection but had progressively less faith in its usefulness. Hitler's long-term goals included annexing Polish territories and subordinating the remaining parts of Poland, an idea that he revealed to his closest circle already in 1933 Poland's solution was to maintain normal and friendly relations with Nazi Germany, with hostility toward the Soviet Union.
Following a border incident in March 1938, Poland presented an ultimatum to Lithuania, demanding the re-establishment of diplomatic relations between Poland and Lithuania and the previously closed border with Poland to be reopened. Faced with the threat of war, the Lithuanian government accepted the Polish demands. In October 1938, the Munich Agreement, with British and French approval, allowed Germany to take over areas of Czechoslovakia with a significant German minority, the so-called Sudetenland. Poland had long been hostile to Czechoslovakia and now sided with Germany. Poland demanded that Czechoslovakia give up the Teschen, where Poles made about 70% of inhabitants, or otherwise Poland threatened to take it by force. Faced with an ultimatum from both Poland and Germany, Czechoslovakia gave up the area, which was annexed by Poland on October 2, 1938.
In early 1939, Germany invaded the rest of Czechoslovakia, which, in March 1939, then ceased to exist. Germany had demanded that Poland join the Anti-Comintern Pact as a satellite state of Germany. Germany demanded an extraterritorial highway connecting Germany proper with Danzig and then East Prussia, which would cut off Poland from the sea and its main trade route to which Poland refused. Germany also pressed for the incorporation of Danzig, a Nazi ruled city-state with a 90% German population that had been separated from Germany in 1920 and functioning as a Free City in a customs union with Poland ever since.
After it rejected German territorial demands regarding Danzig and Gdansk Pomerania, Poland's position was steadily weakening as other nations such as Hungary and Romania gravitated toward Germany's orbit. Poland was at the time allied with Romania and France.
Two critical developments caught Poland by surprise. At the end of March 1939, Britain and France announced that if Germany invaded Poland they would declare war. In terms of helping Poland in an actual war, everyone realized they could do very little. The hope was that the threat of a two-front war would deter Germany, especially since it had to worry about the role of the Soviet Union. Hitler thought Britain and France were bluffing, but he handled the Soviet problem in late August, by a stunning agreement with Stalin in what amounted to a friendly alliance, which included secret provisions to partition Poland—and indeed divide up much of eastern Europe The British and French offer was not a bluff—they declared war on Germany when it invaded Poland, but neither was in a position to provide serious help. Poland itself had a million-man army (and another million in the reserves), but fell far short in terms of training, air power, artillery, tanks, machine guns, radios, and trucks. The Polish military budget was about 2% of Germany's; its commanding general Marshal Smigly-Rydz was not well prepared for the challenge.
Polish Corridor and Danzig
The Germans wanted a pretext for war and so they launched new demands on Poland. They insisted on a plebiscite to determine the ownership of the "Polish corridor". Only those living in the corridor prior to 1918 would be allowed to vote. The proposal called for a subsequent population exchange that would move all Germans then in Poland out of the final region declared to be "Poland". The same would occur for all Poles living in what was declared, after the vote, to be "Germany". Danzig was to become part of Germany regardless of the vote, but if Germany lost, it was still guaranteed access to East Prussia through an autobahn system that it would administer, stretching from Germany proper to Danzig to East Prussia. If Poland lost the vote, the corridor would go to Germany and the seaport of Gdynia would become a Polish exclave with a route connecting Poland with Gdynia. After the British-French guarantee of support for Poland was announced on April 3, negotiations over Danzig ended. Germany invaded Poland on September 1, 1939. The issue of Danzig was not the cause of the German invasion; Hitler told his generals in May 1939: “It is not Danzig that is at stake. For us it is a matter of expanding our living space in the east and making food supplies secure.” The total destruction of the Polish state, Polish culture, and indeed the Polish population had become Hitler's main objective. He wanted the agricultural land to resettle German farmers.
