550 BCE
Cyrus the Great begins his rise to power by uniting the Persian tribes and overthrowing his grandfather Astyages, king of the Medes. This marks the beginning of the Achaemenid Persian Empire as Cyrus establishes Persian dominance over the Iranian plateau. His victory over the Median Empire creates the foundation for what would become the largest empire the ancient world had ever seen, stretching from India to the Mediterranean.
