What modern day world power did the Roman government highly influence

Rome became the most powerful state in the world by the first century BCE through a combination of military power, political flexibility, economic expansion, and more than a bit of good luck. This expansion changed the Mediterranean world and also changed Rome itself. New institutions, such as provincial government, were created to deal with the management of empire; culture was transformed as outside influences, especially from Greece, came into fashion in Rome; and the city itself was physically transformed by the influx of loot and people brought by successes abroad.
