The Anglo-Saxons were a people who inhabited Great Britain from the 5th century. They comprised people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language. The Anglo-Saxon period denotes the period of British history between about 450 and 1066, after their initial settlement, and up until the Norman conquest.
The 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; the re-establishment of Christianity; a flowering in literature and language; and the establishment of charters and law. The term Anglo-Saxon is also popularly used for the language, in scholarly use more usually called Old English, 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.
