A Hun is historically the term used for a member of a nomadic or semi-nomadic group of steppe peoples who invaded and migrated through Europe in late antiquity, most famously under Attila the Hun in the 5th century. The Huns formed a large, loosely organized confederation rather than a single, centralized state, and they played a significant role in reshaping the late Roman world through raids, rapid mobility, and military tactics such as mounted archery. They originated in the Eurasian steppe and interacted with a variety of other peoples as they moved westward, influencing the political landscape of Europe for a time. If you’re looking for specifics, I can tailor explanations to these common angles:

• Historical overview: origins, migrations, key leaders, and conquests.
• Military characteristics: mounted archery, mobility, and tactics.
• Cultural and social structure: leadership patterns, tribal organization, and economy.
• Legacy: how the Huns affected Roman policy, later medieval perceptions, and their influence on names and terms used in various languages.
