Return to Poland (1869-1873) In 1869, he returned to Poland, where, as a former insurgent, he was imprisoned. Released under an amnesty, he remained under police supervision for many years. In 1873, he acquired a modest estate in the village of Krasne. Contemporary documentation from the village notes that it took several years of hard work before the farm began to turn a profit, with his horse breeding later earning a strong reputation.
Civilian Career (1873-1923) After acquiring the estate, Przanowski became increasingly active in social causes. He participated in
landowner assemblies and worked within the
Land Credit Society, becoming president of its Lublin branch in 1902. From 1913, he served as general counsel of the Lublin Mutual Credit Society and was also the president of the executive committee of the Lublin branch of the
Nobles' Land Bank. He supported local industry, helped organize the Cooperative Sugar Factory Society of Lublin, and was president of the Milejów Sugar Factory. On May 31, 2022, a 120 square meter mural was created in Ostrowiec Świętokrzyski on the wall of the Sugar Industry Memory Chamber, featuring Leon Przanowski, Henryk Łubieński, and the Izabelin Sugar Factory in Glinojeck. The artwork highlights the contribution of sugar industry figures to Poland's fight for independence. He also founded the Lublin Agricultural Society, promoting the use of artificial fertilizers, catch crops, and fodder. On August 11, 1905, Przanowski, his brother-in-law Tadeusz Rojowski, and several other citizens of Lublin established a humanistic school known as the Eight-Year Private Philological School of Lublin, popularly called the Lublin School. It later became known as the Stefan Batory Private Boys’ High School, a landmark in Lublin's educational history. His influence also led to the establishment of the
H. Łopaciński Public Library on April 26, 1908. Around this time, he became involved with the Lublin Charitable Society and during
World War I, he organized aid for those in need, including veterans of the
January Uprising. ==Late life (1923-1924)==
