Anglia 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 settlers in East Anglia, Central and Northern England, and the Eastern Scottish Lowlands. Their migration led to their new homeland being named after them, from which the name "England" derives. England, East, Mid and West Anglia as well as the English language, thus, ultimately derive at least their names from Anglia. Additionally, Glücksburg Castle in Glücksburg in the north of Anglia, is the seat of the House of Schleswig-Holstein-Sonderburg-Glücksburg, of which the future kings of the United Kingdom are patrilineal members.
