What was the time called when culture spread throughout places that were not greek?

During the Hellenistic Period, which lasted from Alexander’s death until the first century CE, Greek thought and culture became entwined with that of the indigenous populace, a process which is called Hellenization. In addition to the Hellenistic empires, a new wave of Greek colonization infused these regions with Greek influence.

The Marshall Plan helped Western Europe recover from the damage dealt to their region by recovering trade, restraining inflation, and reinstating production. It also helped restore infrastructure via counterpart funds.
