Geneticists have unlocked the secrets of matriarchy in Iron Age Britain

They studied more than 50 genomes of people buried in cemeteries in the county of Dorset, southern England, dating from before and after the Roman conquest in 43 AD. The findings, published in the journal Nature, showed that this society was centred around women and their family ties.

Dr Lara Cassidy and her colleagues analysed the structure of one large ancestral cemetery. They were able to reconstruct the family tree of the ancient community and found that most people were descended maternally from a single woman who lived many centuries ago. At the same time, paternal lineage was almost non-existent. This suggests that at the time of marriage, men passed into the community from their wives, and property may have been passed down the female line. Such a system, called matrilocalisation, has not previously been documented in prehistoric Europe. It suggests a high role for women in the social and political life of the time.

The study was not limited to just one cemetery. Reviewing data from previous genetic studies of other Iron Age cemeteries across Britain, scientists found a similar pattern: in many burials, people were descended from more than one dominant matrilineage. In Yorkshire, for example, there was already one major maternal line before 400 BC. This confirms that matrilocal communities were spread across the island and had deep roots.

Iron Age cemeteries with well-preserved remains are rare in Britain, but Dorset was an exception due to the customs of the local people, called 'durotriges' by the Romans. Excavations around the village of Winterbourne Kingston, which archaeologists call 'Dupolis', have uncovered rich funerary objects, especially from women, also confirming their important role in society.

Roman writers such as Julius Caesar wrote about strong British women, such as Queen Buzdica and Cartimandua. New genetic evidence supports this historical evidence, showing that women did play a leading role in society. They likely wielded power and influenced political and economic decision-making.

Researchers have also found evidence of migration to the coastal areas of southern England during the Iron Age. These discoveries could affect the debate about when and how the Celtic language came to Britain, as migrations may have been much more active than previously thought.

According to Dr Cassidy, the matrilocality observed in this study could have led to the social and political empowerment of women - a rare phenomenon even in modern times. These genetic discoveries break new ground in understanding ancient communities and their culture.
