Starting in about 200 AD, the Chernyakhov culture became established in the modern-day western Ukraine and Moldova region inhabited by the Bastarnae. The culture is characterised by a high degree of sophistication in the production of metal and ceramic artefacts, as well as of uniformity over a vast area. Although this culture has conventionally been identified with the migration of the Gothic "ethnos" into the region from the northwest, Todd argues that its most important origin is Scytho-Sarmatian. Although the Goths certainly contributed to it, so probably did other peoples of the region such as the Dacians, proto-Slavs, Carpi and possibly the Bastarnae.
