How did the Romans influence trade and writing in Iron Age Denmark?

During the Iron Age, the Roman Empire significantly influenced Denmark through the establishment of more-or-less fixed trading connections.12

Regarding writing, these interactions are believed to have influenced the development of the runic alphabet. The first runic inscriptions appeared in Denmark by about 200 ce; scholars suggest these were likely inspired by the Etruscan alphabet of northern Italy, with possible additional influence from the Latin alphabet.12
