Final answer:
The Vikings were early developers who expanded their influence to North America but their attempted colonization failed. They settled in the lands they had formerly raided and eventually resembled other medieval Europeans.
Step-by-step explanation:
The Vikings were early developers who expanded their influence from Russia to Iceland and even to North America. They believed in exploring and settling in new lands, and their longships provided them with a strategic advantage at sea. The Vikings were the first Europeans to arrive in North America, but their attempted colonization failed due to conflicts with the indigenous people. While the Vikings were known for their raids, they eventually settled in the lands they had previously raided and resembled other medieval Europeans.
