A series of exceptionally dry summers that caused famine and social breakdown were behind one of the most severe threats to Roman rule of Britain, according to new academic research.The rebellion, known as the “barbarian conspiracy”, was a pivotal moment inRoman Britain. Picts, Scotti and Saxons took advantage of Britain’s descent into anarchy to inflict crushing blows on weakened Roman defences in the spring and summer of AD367.Senior Roman commanders were captured or killed, and some soldiers reportedly deserted and joined the invaders. It took two years for generals dispatched by Valentinian I, emperor of the western half of the Roman empire, to restore order. The last remnants of official Roman administration left Britain about 40 years later.Warning of the possible consequences of drought today, Tatiana Bebchuk, a researcher at Cambridge’s department of geography, said: “The relationship between climate and conflict is becoming increasingly clear in our own time, so these findings aren’t just important for historians. Extreme climate conditions lead to hunger, which can lead to societal challenges, which eventually lead to outright conflict.”The study, published in Climatic Change, used oak tree-ring records to reconstruct temperature and precipitation levels in southern Britain during and after the barbarian conspiracy. Combined with surviving Roman accounts, the data led the authors to conclude that severe summer droughts were a driving force.Little archaeological evidence for the rebellion existed, and written accounts from the period were limited, said Charles Norman of Cambridge’s department of geography. “But our findings provide an explanation for the catalyst of this major event.”Southern Britain experienced an exceptional sequence of remarkably dry summers from AD364 to 366, the researchers found. In the period AD350-500, average monthly reconstructed rainfall in the main growing season was 51mm. But in AD364, it fell to 29mm. AD365 was even worse with 28mm, and the rainfall the following year was still below average at 37mm.Prof Ulf Büntgen of Cambridge’s department of geography said: “Three consecutive droughts would have had a devastating impact on the productivity of Roman Britain’s most important agricultural region. As Roman writers tell us, this resulted in food shortages with all of the destabilising societal effects this brings.”The researchers identified no other major droughts in southern Britain in the period AD350-500 and found that other parts of north-west Europe escaped these conditions.By AD367, the population of Britain was in the “utmost conditions of famine”, according to Ammianus Marcellinus, a soldier and historian.Norman said the poor harvests would have “reduced the grain supply to Hadrian’s Wall, providing a plausible motive for the rebellion there, which allowed the Picts into northern Britain”.The study suggested that grain deficits may have contributed to other desertions in this period, and therefore a general weakening of the Roman army in Britain.skip past newsletter promotionSign up toHeadlines UKFree newsletterGet the day’s headlines and highlights emailed direct to you every morningEnter your email addressSign upPrivacy Notice:Newsletters may contain info about charities, online ads, and content funded by outside parties.

TruthLens AI Summary
Recent research has revealed that a series of severe droughts in the mid-fourth century AD played a crucial role in instigating one of the most significant threats to Roman authority in Britain, referred to as the 'barbarian conspiracy.' This rebellion, which unfolded in AD367, involved various tribes such as the Picts, Scotti, and Saxons capitalizing on the weakened state of Roman defenses due to famine and social disarray. The study, conducted by researchers at Cambridge University, utilized oak tree-ring data to reconstruct climatic conditions during this tumultuous period. Findings indicated that southern Britain suffered from an exceptional sequence of dry summers between AD364 and 366, which drastically reduced rainfall and led to crop failures. This agricultural collapse not only resulted in widespread hunger but also triggered societal instability, making the region vulnerable to external attacks. Key Roman military leaders were either killed or captured, while some soldiers deserted, exacerbating the situation for Roman forces tasked with maintaining order in Britain.
The implications of this research extend beyond historical understanding, as they highlight the relationship between climate change and societal conflict, a theme relevant to contemporary discussions. Tatiana Bebchuk, one of the study's researchers, emphasized that extreme climatic events can lead to food shortages, which in turn foster social unrest and potential conflicts. The historical analysis revealed that the drought conditions experienced in Britain were not replicated in other parts of north-west Europe during the same period, which further isolated the Roman province. The findings serve as a reminder of how environmental factors can precipitate dramatic political and military changes, as seen with the Roman Empire's decline in Britain. As noted by the researchers, the consequences of these droughts were profound, contributing to a weakening of military strength and ultimately facilitating the invasion of peripheral tribes, thus marking a significant turning point in the history of Roman Britain.
