context_page_description: The history of Poland spans over a thousand years, from medieval tribes, Christianization and monarchy; through Poland's Golden Age, expansionism and becoming one of the largest European powers; to its collapse and partitions, two world wars, communism, and the restoration of democracy.
  The roots of Polish history can be traced to the Iron Age, when the territory of present-day Poland was settled by various tribes including Celts, Scythians, Germanic clans, Sarmatians, Slavs and Balts. However, it was the West Slavic Lechites, the closest ancestors of ethnic Poles, who established permanent settlements in the Polish lands during the Early Middle Ages. The Lechitic Western Polans, a tribe whose name means "people living in open fields", dominated the region, and gave Poland - which lies in the North-Central European Plain - its name.
  The first ruling dynasty, the Piasts, emerged in the 10th century AD. Duke Mieszko I is considered the de facto creator of the Polish state and is widely recognized for his adoption of Western Christianity in 966 CE.
context_section_description: Independence stimulated the development of Polish culture in the Interbellum and intellectual achievement was high. Warsaw, whose population almost doubled between World War I and World War II, was a restless, burgeoning metropolis. It outpaced Kraków, Lwów and Wilno, the other major population centers of the country.
  Mainstream Polish society was not affected by the repressions of the Sanation authorities overall; many Poles enjoyed relative stability, and the economy improved markedly between 1926 and 1929, only to become caught up in the global Great Depression. After 1929, the country's industrial production and gross national income slumped by about 50%.
  The Great Depression brought low prices for farmers and unemployment for workers. Social tensions increased, including rising antisemitism. A major economic transformation and multi-year state plan to achieve national industrial development, as embodied in the Central Industrial Region initiative launched in 1936, was led by Minister Eugeniusz Kwiatkowski. Motivated primarily by the need for a native arms industry, the initiative was in progress at the time of the outbreak of World War II. Kwiatkowski was also the main architect of the earlier Gdynia seaport project.
  The prevalent in political circles nationalism was fueled by the large size of Poland's minority populations and their separate agendas. According to the language criterion of the Polish census of 1931, the Poles constituted 69% of the population, Ukrainians 15%, Jews (defined as speakers of the Yiddish language) 8.5%, Belarusians 4.7%, Germans 2.2%, Lithuanians 0.25%, Russians 0.25% and Czechs 0.09%, with some geographical areas dominated by a particular minority. In time, the ethnic conflicts intensified, and the Polish state grew less tolerant of the interests of its national minorities. In interwar Poland, compulsory free general education substantially reduced illiteracy rates, but discrimination was practiced in a way that resulted in a dramatic decrease in the number of Ukrainian language schools and official restrictions on Jewish attendance at selected schools in the late 1930s.
  The population grew steadily, reaching 35 million in 1939. However, the overall economic situation in the interwar period was one of stagnation. There was little money for investment inside Poland, and few foreigners were interested in investing there. Total industrial production barely increased between 1913 and 1939 (within the area delimited by the 1939 borders), but because of population growth (from 26.3 million in 1919 to 34.8 million in 1939), the per capita output actually decreased by 18%.
  Conditions in the predominant agricultural sector kept deteriorating between 1929 and 1939, which resulted in rural unrest and a progressive radicalization of the Polish peasant movement that became increasingly inclined toward militant anti-state activities. It was firmly repressed by the authorities. According to Norman Davies, the failures of the Sanation regime (combined with the objective economic realities) caused a radicalization of the Polish masses by the end of the 1930s, but he warns against drawing parallels with the incomparably more repressive regimes of Nazi Germany or the Stalinist Soviet Union.
