The ancient empire ruled by Cyrus the Great was the Persian Empire. Established in the mid-6th century BCE, it became one of the largest empires in history, stretching from the Mediterranean Sea to the Indus River. Cyrus is remembered for his innovative approach to governance, including respect for the customs and religions of the lands he conquered. He is notable for the implementation of the Cyrus Cylinder, often regarded as the first charter of human rights, which exhibited his policies of tolerance and statecraft. His legacy set the stage for centuries of Persian dominance in the region.
