The Iron Age follows the Bronze Age, and begins with the development of technology for extracting iron ore from rocks.
The Iron Age describes culture from c. 850 BC to the birth of Christ, and is divided into two periods, the 1st Iron Age, called the Halstatt period, and the 2nd Iron Age, called the La Tène period.
