The Roman conquest of Britain, far from a swift military campaign, was a prolonged and bloody conflict marked by brutal warfare, shifting alliances, and profound societal changes, according to Ferdinand Addis's new book, "Conquest."

The initial Roman incursions in 55 and 54 BC under Julius Caesar are characterized as largely ineffective PR stunts that achieved little militarily. The true conquest began in AD 43, a process that saw ordinary Britons subjected to slaughter and enslavement, while the British elite often collaborated with the invaders, gaining rewards such as wine, silver, and opulent villas.

Resistance and Romanization

Not all Britons submitted easily. Figures like Caratacus, whose actual name was likely Caradoc, mounted significant resistance, employing guerrilla tactics against the formidable Roman legions. Despite years of conflict, Caratacus was eventually defeated in the hills of Wales and, betrayed by Queen Cartimandua of the Brigantes, was handed over to the Romans. While captured, Roman admiration for his spirit reportedly allowed him to live out his years in Rome.

Another notable uprising occurred in AD 61, led by Boudica, who led a furious revolt after she and her daughters were flogged and raped. Her forces razed Colchester and London, inflicting heavy casualties, but were ultimately subdued by Roman military discipline. The book highlights the stark contrast between the disciplined, unit-based Roman warfare and the more individualistic, though visually striking, combat style of the Britons, known for their elaborate moustaches, woolen capes, and chariot displays.

Social and Genetic Legacies

Beyond the battlefield, the Roman presence led to significant cultural and social changes. The book notes how conquered tribes, including their chieftains, had to adapt to Roman governance and ideology. Romanization extended to the landscape, with sites like the hot springs in southwest England, known today as Bath, being transformed.

Addis also delves into deeper historical currents, including the origins of the British population. The book touches upon the Yamnaya people from the steppes, who around 3000 BC migrated across Europe. These groups, characterized as aggressive horse and chariot riders, are linked to significant genetic shifts in Europe, with analyses showing a substantial influence on the male DNA of modern native Britons, a legacy of conquest and intermingling.

The Roman military machine, described as a force of highly skilled laborers whose work was death, operated with relentless efficiency. The narrative suggests a routine nature to their violence, with historical accounts of soldiers engaging in cruel diversions during sieges. This disciplined approach, operating in units known as legions, often proved decisive against less organized opposition.

Ultimately, "Conquest" portrays the Roman occupation not just as a military event but as a complex, transformative period that reshaped Britain's society, culture, and even its genetic makeup, echoing the sentiments of the British chieftain Calgacus, who is recorded as lamenting that the Romans "create a desert and they call it peace."
