For more than 70 years, historians have been trying to determine the authorship of the words to the song O Warmia my love, which became the anthem of Warmia. Although in May 1920 the “Gazeta Olsztyńska” published the song, stating its words were written by Maria Paruszewska from Poznań, its authorship was questioned. She was nonetheless the author of the Warmian Hymn. The song O Warmia, my love, was printed for the first time on 9 May 1920, together with Feliks Nowowiejski, nine days earlier than in Olsztyn, in the illustrated social and national weekly „Praca”, which was then edited in Poznań.
