of Polish Positivism included: Young Poland (1890–1918) The modernist period known as the Young Poland movement in visual arts, literature and music, came into being around 1890, and concluded with the Poland's return to independence (1918). The period was based on two concepts. Its early stage was characterized by a strong aesthetic opposition to the ideals of its own predecessor (promoting organic work in the face of foreign occupation). Artists following this early philosophy of Young Poland believed in decadence, symbolism, conflict between human values and civilization, and the existence of art for art's sake. Prominent authors who followed this trend included Kazimierz Przerwa-Tetmajer, Stanisław Przybyszewski and Jan Kasprowicz. The later ideology emerged in conjunction with the socio-political upheavals across Europe such as the 1905 Revolution against Nicholas II of Russia, the Norwegian independence, the Moroccan Crisis and others. It was a continuation of romanticism, often called neo-romanticism. The artists and writers following this idea covered a large variety of topics: from the sense of personal mission of a Pole exemplified by Stefan Żeromski's prose, through condemnation of social inequality in works by Władysław Reymont and Gabriela Zapolska, to criticism of Polish society and Polish revolutionary history by Stanisław Wyspiański. In 1905 Henryk Sienkiewicz received a Nobel Prize in literature for his patriotic Trilogy inspiring a new sense of hope.

In large part, derivative of these changes was the collective and unobstructed development of programs for artists and writers. New avant-garde trends had emerged. The period, spanning just twenty years, was full of notable individualities who saw themselves as exponents of changing European civilization, including Tuwim, Witkacy, Gombrowicz, Miłosz, Dąbrowska and Nałkowska (PAL). They all contributed to a new model of the twentieth-century Polish culture echoing its own language of everyday life.Prof. Marian Stala of Jagiellonian University, 1989: Dwa dwudziestolecia (jednej epoki).

The two decades of Interbellum were marked by rapid development in the field of poetry, undivided and undiminished for the first time in over a century. From 1918 to 1939, the gradual and successive introduction of new ideas resulted in the formation of separate and distinct trends. The first decade of Polish interwar poetry was clear,
