How many countries did Rome take over all together?

At its height, the Roman Empire controlled approximately 50 countries across Europe, North Africa, and parts of the Middle East. This vast territory included regions that are now modern-day Italy, Spain, France, Greece, Turkey, Egypt, and many others. The empire expanded through a combination of military conquest, diplomacy, and colonization. The exact number can vary depending on historical interpretations and the definition of "countries," but the empire's reach was extensive.
