The Angles (, ; ) were one of the main Germanic peoples who settled in Great Britain in the post-Roman period. They founded several kingdoms of the Heptarchy in Anglo-Saxon England. Their name is the root of the name England ("land of Ængle"). According to Tacitus, writing around 100 AD, a people known as Angles (Anglii) lived east of the Lombards and Semnones, who lived near the Elbe river. Etymology The name of the Angles may have been first recorded in Latinised form, as Anglii, in the Germania of Tacitus. It is thought to derive from the name of the area they originally inhabited, the Anglia Peninsula (Angeln in modern German, Angel in modern Danish). Multiple theories concerning the etymology of the name have been hypothesised: According to Gesta Danorum Dan and Angul (Angel) were made rulers by the consent of their people because of their bravery. Dan gave name to Danes and Angel gave names to Angles. It originated from the Germanic root for "narrow" (compare German and Dutch eng = "narrow"), meaning "the Narrow [Water]", i.e., the Schlei estuary; the root would be *h₂enǵʰ, "tight". The name derives from "hook" (as in angling for fish), in reference to the shape of the peninsula; Indo-European linguist Julius Pokorny derives it from Proto-Indo-European *h₂enk-, "bend" (see ankle). Alternatively, the Angles may have been called such because they were a fishing people or were originally descended from such. During the fifth century, all Germanic tribes who invaded Britain were referred to as either Englisc, Ængle or Engle, who were all speakers of Old English (which was known as Englisc, Ænglisc, or Anglisc). Englisc and its descendant, English, also goes back to Proto-Indo-European *h₂enǵʰ-, meaning narrow. Pope Gregory I, in an epistle, simplified the Latinised name Anglii to Angli, the latter form developing into the preferred form of the word. The country remained Anglia in Latin. Alfred the Great's translation of Orosius's history of the world uses Angelcynn (-kin) to describe the English people; Bede uses Angelfolc (-folk); also such forms as Engel, Englan (the people), Englaland, and Englisc occur, all showing i-mutation. Greco-Roman historiography Tacitus The earliest known mention of the Angles may be in chapter 40 of Tacitus's Germania written around AD 98. Tacitus describes the "Anglii" as one of the more remote Suebic tribes compared to the Semnones and Langobardi, who lived on the Elbe and were better known
