Danpi Havarsdatter, Queen of Jutland

Modern Angeln, also known as Anglia (German: Angeln, Danish: Angel, Latin: Anglia, English: may follow German or Latin; direct translation from Latin: England), is a peninsula in Southern Schleswig in the northern Schleswig-Holstein, Germany, protruding into the Bay of Kiel. It is separated from the neighbouring peninsula of Schwansen (Danish: Svans or Svansø) by the Schlei inlet, and from the Danish island of Als by the Flensburger Förde ("Firth of Flensburg"). Whether ancient Angeln conformed to these borders is uncertain. It may have been somewhat larger; however, the ancient sources mainly concur that it included the territory of modern Angeln.

Angeln has a significance far beyond its current small area and country terrain, in that it is believed to have been the original home of the Angles, Germanic immigrants to central and northern England, and East Anglia. This migration led to their new homeland being named after them, from which the name "England" derives. English, a major language of the modern world, derives its name from the Angles and Angeln.
