Cyrus the Great was the founder of the Achaemenid Empire, which became the largest empire in the ancient world. He ruled from 559 to 530 BCE and is known for his innovative approach to governance, including respect for the customs and religions of the lands he conquered. His leadership style helped unify a diverse range of cultures under one empire. Cyrus is also famous for the Cyrus Cylinder, often considered the first charter of human rights. This artifact outlines his policies of tolerance and justice, particularly regarding the treatment of conquered peoples, including the Babylonians and Jews. His legacy continues to influence leaders and cultures today.
