Poland (1939) Poland in 1939 was the Second Polish Republic, a multiethnic Second Polish Republic state situated between Nazi Germany and the Soviet Union. Politically dominated by the Sanation regime under Józef Piłsudski’s legacy, led by President Ignacy Mościcki and Prime Minister Felicjan Sławoj Składkowski, Poland faced mounting threats from Adolf Hitler’s Nazi Germany and Joseph Stalin’s Soviet Union. The year culminated in the Invasion of Poland and profound territorial, social, and humanitarian upheaval.
Background and political situation
In the interwar years the Second Polish Republic navigated tensions from the Treaty of Versailles, the Polish–Soviet War, and border disputes with Czechoslovakia, Lithuania, and Germany. The political landscape featured factions such as Sanation, the Polish Socialist Party, the Polskie Stronnictwo Ludowe, and the conservative Nonpartisan Bloc for Cooperation with the Government. The legacy of Józef Piłsudski shaped civil-military relations through the Polish Army and institutions like the Polish State Police and the Ministry of Military Affairs (Poland). Ethnic minorities included Jews, Ukrainians, Belarusians, Germans, and Lithuanians, concentrated in regions such as Kresy, Galicia, and Silesia. Economic and diplomatic efforts involved links to France, United Kingdom, and the Little Entente while facing ideological challenges from Nazism and Communism.
Invasion and military campaigns
War began with the Invasion of Poland launched by Nazi Germany on 1 September 1939, employing the Blitzkrieg strategy supported by units like the Wehrmacht and formations from the Luftwaffe. Key early battles included the Battle of Westerplatte, the Siege of Warsaw (1939), the Battle of the Bzura, and fighting around Gdynia and Hel (peninsula). On 17 September 1939 the Soviet invasion of Poland commenced as the Red Army crossed the Molotov–Ribbentrop Pact’s secret protocols demarcating spheres with Nazi Germany. Polish forces under commanders such as Edward Rydz-Śmigły, Władysław Sikorski, and Tadeusz Kutrzeba conducted organized resistance, retreats to Romania and Hungary, and defensive actions linked to units like the Polish Air Force (Second Polish Republic). Naval elements of the Polish Navy executed Peking Plan-style evacuations to United Kingdom ports. The combined pressure from Wehrmacht and Red Army led to Poland’s military collapse by early October.
Occupation and administrative changes
Following conquest, Nazi Germany annexed western regions into the Reich and created the General Government administered by Hans Frank, implementing Germanisation policies and territorial reorganization of areas such as Silesia, Pomerania, and Poznań. The Soviet Union incorporated eastern regions into the Ukrainian Soviet Socialist Republic, Byelorussian Soviet Socialist Republic, and transferred territories under Molotov–Ribbentrop Pact arrangements, installing Soviet administrative structures and NKVD operations. Property seizures, deportations to places like Siberia and Kazakh SSR, and the dissolution of Polish institutions accompanied the creation of puppet administrations and Volksdeutsche-oriented settlements. Borders imposed by German–Soviet Frontier Treaty (1939) further solidified occupation regimes.
Humanitarian impact and population movements
Occupation triggered massive civilian suffering: expulsions, forced labor, mass arrests, and targeted violence against Jews, Poles, Ukrainians, and other communities. Events such as the Sonderaktion Krakau and early massacres foreshadowed later atrocities including the Katyn massacre (later in 1940) and widespread persecution by the Gestapo and NKVD. The Polish Jewish population faced ghettoisation beginning in cities like Łódź, Warsaw, and Kraków. Large-scale deportations sent civilians to gulag camps, transit camps, and forced labor in the Reich. Refugee flows moved thousands to Romania, Hungary, Lithuania, and Soviet Union territories; many servicemen and officials escaped to France and the United Kingdom to continue resistance.
International reactions and diplomacy
The United Kingdom and France declared war on Nazi Germany on 3 September 1939 in fulfillment of alliance commitments, initiating the Phoney War period with limited direct military assistance to Poland. Diplomatic efforts included appeals to the League of Nations, and negotiations involving Benito Mussolini’s Italy, Vladimir Lenin’s legacy debates, and shifting stances in capitals like Washington, D.C. and Rome. The Molotov–Ribbentrop Pact shocked Western governments and complicated relief; subsequent treaties and statements, including guarantees to Poland issued earlier by Neville Chamberlain and Édouard Daladier, had limited immediate effect. The fall of Poland reshaped strategic calculations leading to the Battle of France and wider World War II escalation.
Resistance and Polish government-in-exile
Polish leadership fled and reconstituted itself as the Polish government-in-exile first in France and later in London, led by figures such as Władysław Sikorski and Ignacy Jan Paderewski’s political legacy influences. Within occupied territory, clandestine structures evolved into the Polish Underground State including the Armia Krajowa (Home Army) and civil organs linked to the Government Delegation for Poland. Covert resistance encompassed sabotage, intelligence passed to British Intelligence, and preparations for uprisings culminating later in the Warsaw Uprising (1944). Exiled forces contributed to Allied operations, forming units like the Polish Air Forces in France and Great Britain and the Polish Armed Forces in the West, maintaining continuity of the Polish Republic’s legal claims and international advocacy.
