When Bavarian settlers moved into the area during the 9th century, superseding and gradually absorbing the Slavic population that had established itself during the previous half-millennium, all recollection of the Roman city had long since faded.

The first documented version of the name Leibnitz reads Lipnizza and can be found in a scroll issued by emperor Otto the Great dated 7 March 970.

From the 1970s onward, when it became easier for Yugoslav citizens to travel to Austria, Leibnitz started to experience a marked economic reinvigoration which gained momentum with the establishment of Slovenia as an independent state in 1991, and its entry into the European Union in 2004.

The elections in 2020 showed the following results:[3] Leibnitz has a cinema, an ice rink located in the center, and an open-air swimming pool with campsite and tennis courts.

Leibnitz lies on the main southern railway line, connecting Vienna to Slovenia and the Croatia- northern parts especially like towns Čakovec or Varaždin via Graz.

The journey from Graz main station to Leibnitz takes approximately 30 minutes using trains travelling to Spielfeld-Straß, Maribor or even Ljubljana or Zagreb.
