What did the Romans ever do for us?
In 2006, as British Euroskepticism was gathering steam, Boris Johnson published a book called The Dream of Rome, in which he held up the Roman Empire as a successful model of European integration and as a foil to the unlovable European Union. That was a rather peculiar choice. You would hardly have expected the future Brexiteer to yearn for a time when Britain was but a marginal province of a ‘European super-state’, a label that Margaret Thatcher had once applied to the EU, yet which is a much better fit for imperial Rome. But Johnson also failed to realize that it had actually been the end of Roman power that launched Europe’s long, tortuous and unique journey toward modernity — a journey in which the sovereign United Kingdom came to play such an outsized role.
