The Hallstatt culture was succeeded by the La Tène culture, which developed out of the Hallstatt culture without any definite cultural break, under the impetus of considerable Mediterranean influence from Greek, and later Etruscan civilizations. The La Tène culture developed and flourished during the late Iron Age (from 450 BC to the Roman conquest in the 1st century BC) in eastern France, Switzerland, Austria, southwest Germany, the Czech Republic, and Hungary. Farther to the north extended the contemporary Pre-Roman Iron Age culture of Northern Germany and Scandinavia.
