The town was founded in early 1920s when, as a result of the Treaty of Versailles, the railroad hub in nearby Zb?szy? (Bentschen) became part of the Second Polish Republic. In 1922, the government of Weimar Germany decided to build a new border station, a new rail hub (which replaced Zbaszyn) as well as a settlement for railroad workers. Within a few years in 1923-30, a large station was constructed, together with a modern suburban type settlement, based on a project by architect Friedrich Veil. The town, named Neu Bentschen, was inhabited by ethnic German railroad workers. There were two churches, a printing shop, a house of culture (Deutsches Haus), a school, a mail office and a bank. The settlement belonged to the Meseritz county.
Following the invasion of Poland in World War II, the Germans opened a forced-labour camp in Zb?szynek, in which various categories of prisoners were kept including POWs from France, Italy, and, after 1941, from the Soviet Union, as well as Jews from the ?ód? Ghetto. Hundreds died of diseases and exhaustion. Those who survived, worked on the rail infrastructure, which was necessary for transports to the Eastern front.
In January 1945 some German inhabitants of Neu Bentschen fled the advancing Red Army and the town was captured without fighting. As a result of the territorial changes of Poland immediately after World War II following the Potsdam Conference, it was part of the German territory transferred to Poland. The remaining populace was expelled to Germany. Neu Bentschen was briefly called Nowy Zb?szy?, some time in late 1940s, the name was changed to Zb?szynek.
