The origin of the name Olkusz is cited as the ancient Phoenician (Canaanite Hebrew) "Elkhuds" meaning "to chisel".
A first written historical document from the year 1299 refers to the city of Olkusz, although it was granted town rights earlier.
Francesco Nullo, hero of the fights for Italian and Polish independence died in the Battle of Krzykawka nearby, and then was buried at the cemetery in Olkusz.
During the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was invaded by Germany.
The German terror campaign against the local population was aimed at the planned Germanisation of the town and the region.
