Hallstatt C is characterized by the first appearance of iron swords mixed amongst the bronze ones. Inhumation and cremation co-occur. For the final phase, Hallstatt D, daggers, almost to the exclusion of swords, are found in western zone graves ranging from c. 600–500 BC. There are also differences in the pottery and brooches. Burials were mostly inhumations. Halstatt D has been further divided into the sub-phases D1–D3, relating only to the western zone, and mainly based on the form of brooches.
