By overrunning the Persian Empire Alexander helped extend Macedonian and Roman rule.?

Answer 1

By conquering the Persian Empire, Alexander the great facilitated the spread of Macedonian influence across a vast territory, effectively uniting regions from Greece to India under his rule. This expansion laid the groundwork for the subsequent rise of Roman power, as the territories Alexander conquered would later be absorbed into the Roman Empire. His campaigns not only spread Hellenistic culture but also established trade routes and administrative practices that would benefit later empires. Ultimately, Alexander's conquests marked a significant shift in the balance of power in the ancient world, paving the way for Roman domination.
