An introduction to Anglo-Saxon England can be found in the text by Peter Hunter Blair.
It would seem that this group of Germanic peoples had something to do with the creation of the kingdom of England as a political entity. They also had something to do with what was to become English as a spoken and written language. Who would have guessed that all this would have come through an invitation of one of those Celtic folks (Vortigern) fighting other Celtic folks? (Picts)
The chapter titles are:
I. The Foundation of England
II. Britain and The Vikings
III. The Church
IV. Government

VI. Letters
First published by the Cambridge University Press in 1956, it has been reprinted in 1960, 1962, 1966, 1970, 1974, 1976, with a second edition printed 1977. Over these years, a few folks must have felt it to be helpful in their understanding of the Anglo-Saxons and their beginnings.
