He shared these experiences in his poem "Dola Śmiertelnika" ("The fate of the mortal"), published in the journal "Przyjaciel Ludu" (issue Nr.3, 1847): there, he expressed his doubts about the effectiveness of the armed insurrection against occupying forces.

The Prussian authorities, aware of his political inclinations, prevented him from taking the state examination, hence barring him the access to teaching positions.

Julian Prejs published his first literary works in 1845–1847 in Poznań's periodical "Kościół i Szkoła" ("Church and School") and in Leszno's Friend of the People [pl].

[2] He then used a pseudonym, "Sjerp-Polaczka", an anagram from his family name: his articles advocated equality for all people, social solidarity and Polish nobility leadership, while his poems aroused patriotic feelings.

[4] "Biedaczek" was the first periodical in the entire Pomerania aiming to shape the national consciousness of the local peasantry, the petty bourgeoisie and the commoners alike.

He tried to fight back by publishing, on 1 April 1849, another separate magazine for women, "Siostrzanka" ("Little sister"), which did not find its audience and soon collapsed.

He published additionally separate writings, such as:[2] At the turn of 1849, Julian Prejs applied to the city council of Chełmża with a request to grant permission to establish a printing house.

The new press law introduced high cash deposits, forcing Prejs to stop publishing "Biedaczek" on 29 June 1850.

[3] Soon he got contacts in Bydgoszcz, where from October 1860 to March 1861, he published 5 issues of the calendar magazine "Wszechbrat Bracki, pismo dla bractw i stowarzyszeń kościelnych a szczególnie Bractw Trzeźwości świętej" (""Wszechbrat Bracki, a magazine for church fraternities and associations, especially the Fraternities of Holy Sobriety").

He collaborated with Stanisław Tomaszewski, a printer and publisher of newspapers "Straż Polska" (Polish Guard) (1891–1894) and Gazeta Bydgoska [pl].

On 27 October 1872, together with Teofil Magdziński, they created the Towarzystwo Przemysłowego w Bydgoszczy ('Industrial Society in Bydgoszcz'), bringing together local notables, craftsmen, workers and small industrialists.

In 1902, when Julian fell into extreme dire, appeals appeared in Poznań and Pomeranian newspapers to rescue the elderly, dying writer.

[11] For the 200th anniversary of Julian Prejs birth, a celebration took place in February 2020, on his tombstone, in the house at 2 Terasy and at the Garrison church.

[12] It was organized by Aleksandra Poeplau (great-great-great-granddaughter of the journalist), Polish scouts and members of the "Society of Bydgoszcz city lovers".
