Ancient DNA study proves Iron Age British women held unprecedented power

Scientists uncover evidence that women controlled property rights and marriage

DUBLIN — Scientists have made a remarkable discovery about women’s roles in ancient British society by analyzing DNA from skeletal remains dating back about 2,000 years. Their research reveals that in Iron Age Britain (roughly 800 BC to 43 AD), communities were organized around powerful female family lines, with daughters staying in their home territories while men moved elsewhere for marriage – a practice that helps explain the emergence of famous warrior queens like Boudica.

When Roman writers first encountered British society, they were struck by how different it was from their own patriarchal culture. They wrote about British women owning property, leading armies, and wielding significant political power. However, historians often dismissed these accounts as exaggerations meant to portray British society as uncivilized. Now, a new study by researchers from Trinity College Dublin and Bournemouth University provides scientific evidence supporting these historical observations.

The research, published in Nature, focused on a burial ground near Winterborne Kingston in southern England, which archaeologists have been excavating since 2009. This site, nicknamed “Duropolis,” belonged to a tribal group called the Durotriges. Even before DNA analysis, archaeologists had noticed something unusual: women’s graves often contained more valuable and diverse items than men’s graves, hinting at their high social status.

“This was the cemetery of a large kin group,” explains Dr. Lara Cassidy, Assistant Professor in Trinity’s Department of Genetics and lead author of the study, in a statement. “We reconstructed a family tree with many different branches and found most members traced their maternal lineage back to a single woman, who would have lived centuries before. In contrast, relationships through the father’s line were almost absent.”

By extracting DNA from 57 skeletons, the research team was able to reconstruct family trees and understand how people were related to each other – much like modern DNA testing services do, but for ancient communities. What they found was surprising: the majority of people buried at the site were related through their mothers’ line to a single woman who lived several generations earlier.

To understand why this is significant, imagine a community where daughters stay in their hometown while sons move away when they marry – the opposite of historical European customs where brides typically moved to live with their husbands’ families. This practice, called matrilocality, often indicates that women hold significant power and property rights within a society.

The maternal lineage found at Winterborne Kingston was remarkably rare – it appears in just 3 out of every 100,000 people today and had never been seen before in ancient DNA studies. This wasn’t simply because there were many sisters buried at the site; in fact, researchers found only two pairs of adult sisters. Instead, it showed that women from this family line had maintained their position in the community over many generations.

The research team found evidence that this social system extended far beyond a single community. When they examined DNA from other Iron Age burial sites across Britain, they found similar patterns. For example, in Yorkshire, nearly 400 miles north of Winterborne Kingston, they discovered a community organized around a dominant maternal lineage that had been established before 400 BC.

The genetic analysis also revealed sophisticated marriage practices. The community appeared to encourage marriages between distant branches of the same extended family while avoiding close interbreeding, suggesting they kept careful track of their genealogy. Most unrelated individuals buried at the site were men, indicating they had moved there from other communities to marry into the local female lineages.

This research also sheds new light on population movements between Britain and continental Europe. The team found evidence of significant migration into southern coastal regions during the Iron Age, which may help explain how Celtic languages spread throughout Britain.

The pattern extended far beyond this single community. “Across Britain we saw cemeteries where most individuals were maternally descended from a small set of female ancestors,” explains Dan Bradley, Professor of Population Genetics at Trinity College Dublin. “In Yorkshire, for example, one dominant matriline had been established before 400 BC. To our surprise, this was a widespread phenomenon with deep roots on the island.”

These findings provide context for historical figures like Queen Boudica, who led a massive uprising against Roman rule, and Queen Cartimandua, who ruled the powerful Brigantes tribe for over 30 years. Rather than being exceptional individuals, these queens emerged from a social system where female leadership was already well-established.
