Hadrian’s Wall. Wikimedia Commons Roman conquest made British people wealthier, research suggests. The usual understanding of pre-industrial economic growth was that it was mainly about expanding populations: More people did more work, but individual people were no richer. Since the industrial revolution, improved technology has increased productivity. The new study looked at archaeological findings, New Scientist reported, including building size and the number of lost coins, to estimate population and wealth over time, and found that Britain at the end of Rome’s rule had a GDP per capita 2.5 times what it was at the start, perhaps driven by safer, more extensive trade, infrastructure including roads and ports, and technology like grain mills and stronger plough animals. |
