Angles (German: Angeln, Old English: Englas, Latin: Angli) were one of the Germanic peoples who migrated from continental Germany to Britain in the 5th century, along with the Saxons and Jutes. That land was later called Engla-lond (in Old English - "Land of the Angles"), thus England. They founded (according to sources such as the Venerable Bede) Northumbria, East Anglia, and Mercia. Thanks to the major influence of the Angles, the people of England are also known as Anglo-Saxons, and, of course English. A region of the United Kingdom is known by the name East Anglia.
The Angle homeland, a small peninsular form in the southern portion of the modern German bundesland of Schleswig-Holstein, itself on the Jutland Peninsula is still called Angeln today, and is formed as a triangle drawn roughly from modern Flensburg on the Flensburger Fjord to Kiel and then to Maasholm on the Schlei inlet. The region's shape, 'an angle' is generally believed to be source Angle toponym, although some suggest angeln as in "to fish" as an alternative.
In any case, this geographic localization of the original Angle tribal group has lead to one of the Anglo-Saxon Invasion's enduring mysteries; namely how it is possible that the Angles were so frequently mentioned as colonizers of ancient Britain while evidence of the also powerful influence of the neighboring Frisians concurrent colonizing activities Britain has been strongly limited to that discoveries in archeological science and more often by un-evidenced though logical deductions and inferences alone. Of course, ethnic Frisians are known to have inhabited the land directly in the path of any invasion route from Angeln to Great Britain and infact, also inhabited lands between the ancient Saxon domaine and Britain, yet they are rarely mentioned as having taken part in the vast migration.
