Roman Coin Minted by Self-Proclaimed Emperor Carausius Found Along UK Railway Route

During excavations for the East West Rail project in Bedfordshire and Cambridgeshire, a silver denarius from 287 C.E. was discovered. This coin was minted by Marcus Aurelius Mausaeus Carausius, a Roman naval officer who proclaimed himself 'emperor of the north' in Britain. Carausius had established a separate state in 286 after acquiring pirate treasure, which displeased co-emperor Maximian. The coin, which served as propaganda highlighting local wealth and agriculture, was found with a late Iron Age vase, pottery shards, and another coin from the era of Antoninus Pius or Marcus Aurelius. Archaeologists have explored 1,000 trial trenches along the railway route connecting Oxford and Cambridge, with plans for an additional 6,000 trenches over two years. Past discoveries include a Bronze Age cemetery, fossils, and ancient jewelry. The coin aids in dating the site, indicating a former Roman settlement. Carausius ruled for seven years before being assassinated in 293 by Allectus, who briefly took over until Constantius captured Britain in 296.
