Anglo-Saxons
The Anglo-Saxons were a cultural group who inhabited Great Britain from the 5th century, and the direct ancestors of the majority of the modern British people. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted many aspects of Anglo-Saxon culture and language; the cultural foundations laid by the Anglo-Saxons are the foundation of the modern English legal system and of many aspects of English society; the modern English language owes over half its words – including the most common words of everyday speech – to the language of the Anglo-Saxons. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.
The early Anglo-Saxon period includes the creation of an English nation, with many of the aspects that survive today, including regional government of shires and hundreds. During this period, Christianity was established and there was a flowering of literature and language. Charters and law were also established. The term "Anglo-Saxon" is popularly used for the language that was spoken and written by the Anglo-Saxons in England and eastern Scotland between at least the mid-5th century and the mid-12th century. In scholarly use, it is more commonly called Old English.

What happened to the indigenous Brittonic people is also subject to question. Heinrich Härke and Richard Coates point out that they are invisible archaeologically and linguistically. But based on a fairly high Anglo-Saxon figure (200,000) and a low Brythonic one (800,000), Brythonic people are likely to have outnumbered Anglo-Saxons by at least four to one. The interpretation of such figures is that while "culturally, the later Anglo-Saxons and English did emerge as remarkably un-British, . . . their genetic, biological make-up is none the less likely to have been substantially, indeed predominantly, British". The development of Anglo-Saxon culture is described by two processes. One is similar to culture changes observed in Russia, North Africa and parts of the Islamic world, where a powerful minority culture becomes, over a rather short period, adopted by a settled majority.
