Final answer:
The hostile Germanic tribes and pirates negatively affected the Roman Empire by raiding territories, disrupting trade, causing economic instability, weakening the military, and contributing to the empire's decline.
Step-by-step explanation:
The hostile Germanic tribes and pirates negatively affected the Roman Empire by constantly raiding and pillaging Roman territories, disrupting trade routes, and causing economic instability. These tribes, such as the Visigoths and Vandals, often targeted coastal regions and sacked cities, which weakened the empire's defenses and forced the Romans to divert resources towards defense rather than further expansion.
Additionally, the Germanic tribes' invasions and clashes with the Roman army led to military setbacks and increased hostility between the two groups. This weakened the overall strength and cohesion of the Roman military, making it difficult for them to maintain control over their vast empire. The ongoing threat posed by these tribes contributed to the eventual fall of the Western Roman Empire.
Overall, the negative actions of the hostile Germanic tribes and pirates had a profound impact on the Roman Empire, contributing significantly to its decline and eventual collapse.
