After World War I, Poland regained independence in 1918, and the region was divided according to the Upper Silesia plebiscite in 1921, whereby 88% of the Lublinitz citizens voted for continuance in the German Weimar Republic, while 47% of the citizens of the entire county voted to join the reborn Polish state. Nevertheless, after Wojciech Korfanty had initiated the Third Silesian Uprising from the nearby village of Czarny Las, it was incorporated into the Silesian Voivodeship of the Second Polish Republic and became a border town. In the interbellum the Polish 74th Infantry Regiment was stationed in Lubliniec.
