Cyrus the Great is often regarded as the "Father of the Persian Empire." He founded the Achaemenid Empire in the 6th century BCE, which became one of the largest empires in history. Known for his enlightened rule, Cyrus implemented policies of tolerance and respect for the customs and religions of the peoples he conquered. His establishment of the charter of human rights, known as the Cyrus Cylinder, emphasized humane governance. Cyrus's legacy also includes the expansion of trade and cultural exchange, setting the foundation for a significant period of prosperity and stability in the ancient world.
