History of the English language can be divided into four stages, which have such names: old english, middle english, early new English and new English language. The first phase lasted for VX centuries AD. In V-VI centuries BC, crossed the North Sea, Britain seized the Anglo-Saxons. Language tribes of Angles, Saxons, Frisians and Jutes belonged to the Germanic group of Indo-European languages, more precisely, to the western subgroup. And in the IX century AD expression "English" applied to all Germanic dialects that were distributed at that time in Britain.
Modern English, in some measure, akin to German, Dutch and Flemish language, which belong to the West German sub-languages, and has some differences from the Danish, Icelandic, Swedish and Norwegian language relating to the North German subgroup. The language which is spoken in Iceland, retained the features of Old English language today, whereas in modern British English they totally lost. Educational history of settlements in Britain and the history of England described in his work "Ecclesiastical History of the people of England" Bede (Anglo-Saxon monk and chronicler) in 731 AD. Thus, in studying his writings, you can see that in the year 449 AD on the island invaded by Jutes Tenet, who came from Jutland. With time they settled down and started the Isle of Wight, southern Hampshire and Kent. The rest of Britain, on the south side of the River Thames taken Saxons who came from Holstein. The northern part of the lands conquered England, who came from Schleswig. Further details can be found at Senator of Arizona, an internet resource.
