In what is very much an archeologist's history of early medieval Britain, Max Adams charts, with much success, the story of the British Isles from the last days of the Roman administration through the semi-mythological fifth century and onto the establishment of the Germanic kingdoms and the re-emergence of Roman Christianity by the turn of the eighth century, primarily through the study of archeological excavations and surviving artefacts.
Adams presents a coherent narrative of evolution rather than revolution and propounds two essential, and conciliatory, theories, first that the end of Roman rule was not an abrupt event, but rather a process from the late fourth century to the mid-point of the following century, and, secondly, that the Germanic migrations of the fifth and sixth centuries were not invasions by massed hordes, but rather a continual, even reciprocal, process of movement by small groups of settlers across the Channel along established continental, Roman trade routes. For Adams then, the history of Britain between 370 and 700 AD is very much a continuity, as imperium gives way to kingdoms, and the English peoples emerge not as Germanic outsiders imposing their culture by conquest, but as an assimilated nation of merged insular and continental races with Germanic elements firmly grafted onto and in sympathy with the rich and vibrant surviving culture of the Romano-British.
From a methodological point of view, Adams has to decide how to reconcile the emerging archeological evidence from this most hidden period of British history with the surviving narratives and chronicles, most vitally those of Gildas, Nennius, Bede, and the Anglo-Saxon Chronicle, and not surprisingly, as an expert in material culture, he always asserts the primacy of the archeological record, even when unclear and contested, when in dispute with the written sources. There is much to be said for this approach, however, it can lead him into being both somewhat dismissive of and underestimating the importance of the narratives, even those like Bede and the Chronicle written long after the events they retell, as transmitters of an oral tradition of the origins of and early settlements of the English, a transmission which posits a more dramatic history of a collapsed and decayed post-Roman world made anew through an influx of aggressive Germanic warriors and farmers, who displace the surviving Romano-British and establish new kingdoms, which in the seventh century are all Christianised under papal rule, thus healing the breach between Britain and Rome made in 410 when Aëtius, as magister equitum in the West, was unable to assist the Britons against Saxon and Irish raiders, advising them to look to their own resources. And while, as Adams rightly points out, there is insufficient archeological evidence to support either an abrupt end to Roman rule or a violent and effective Germanic conquest, it is nonetheless true that to the Romano-British Gildas and the Northumbrian Bede, separated as they were by nearly two centuries, such was the story they believed to be the case and such was believed by their readers, and so such must be respected as a viable narrative by the historian and only refuted by unquestionable evidence which contradicts the writers in matters of fact. Their narratives may be flawed, but in telling the stories as recorded by Britons and English of their time, they are in their own ways telling a true story, if only in recording what contemporaries believed about the world in which they lived, a world we can only ultimately understand through them, although such a position is naturally more that of the historian than the archeologist.
Whatever the actuality, something as hidden from us today as much as it was from Bede and the chroniclers of the ninth century, what is beyond doubt is that at the end of the period in this book, that is by the beginning of the eighth century, with the widespread acceptance of Roman Christianity within settled kingdoms with their own, even if partially mythical, histories, written by a literate, Latinate, ecclesiastical hierarchy, what has come to be recognised as Anglo-Saxon England, a society which despite its political viscicitudes was to last beyond the Norman Conquest, was fully in place.
So, even if we cannot know for sure how this came about, we can be pretty certain of what was the result, although questions still remain as to how much this was a new, migrant society and how much a development of the evolution of Romano-British society after the withdrawal of Roman authority and the primarily peaceful settlement of the lowlands by continental peoples with previous experience through trade and military service with the post-Roman rulers of the British Isles. For Adams, it is this latter narrative of continuity formed from the archeology which is most justifiable, and in this very readable, well written, and fully researched book, he makes a very strong case for it, even if Bede writing his Historia might differ.
