But, as far as Britain and Western Europe is concerned, the Romans made better use of those weapons and civilisation than did the Greeks or Celts. The Greeks only established enclaves on the coast from which they traded to the locals, and the various Celtic tribes never stopped fighting each other long enough to build a stable, peaceful, prosperous empire.

That's why we have more traces of Roman language and civilisation than we do Celtic or Greek.
