A Germanic people on the Angeln peninsula (modern Schleswig-Holstein), first recorded by Tacitus around 100 AD living near the Elbe beyond the Langobardi and Semnones; their homeland gives its name to England and English.
From the mid-5th century onward, most of the Angles migrated to Britain, founding the kingdoms of the Heptarchy (Northumbria, Mercia, East Anglia); a residual population is later attested in Angeln into the medieval period.
