Radagaisus
Radagaisus (died 406) was a Gothic king who led a large-scale barbarian invasion of Roman Italy in late 405, crossing the Alps with an estimated host of 200,000 to 400,000 warriors and dependents bent on plunder and pagan sacrifices.[1] A committed pagan unaffiliated with Alaric's Visigoths despite prior confederation, he rejected Roman negotiations and ravaged northern Italy, prompting the magister militum Stilicho to mobilize a multinational force including Huns and Alans after overcoming political delays.[1] Stilicho hemmed in Radagaisus' army near Faesulae (modern Fiesole), cutting off supplies and forcing starvation, which led to the invaders' collapse without a pitched battle; Radagaisus attempted flight but was captured and promptly executed.[1] The remnants, numbering in the tens of thousands, were sold into slavery at nominal prices, with many perishing from privation, marking one of the last major Roman victories against a barbarian incursion but highlighting the empire's reliance on irregular auxiliaries.[1] Scholarly accounts, drawing primarily from Orosius and Zosimus, debate the precise ethnic makeup of Radagaisus' followers, traditionally deemed Gothic but potentially including diverse groups like Sarmatians or Victohali, reflecting the fluid tribal alliances of the era.[2]
