What contribution Greece or Rome do you think had the greatest impact on the modern world?

Both Greece and Rome made significant contributions to the modern world, but the establishment of democratic principles by Greece arguably had the greatest impact. The concept of democracy, particularly as it was practiced in Athens, laid the foundation for modern political systems that emphasize citizen participation and individual rights. Additionally, Roman contributions to law, architecture, and engineering, such as the development of legal frameworks and infrastructure, have also profoundly influenced contemporary society. Together, these legacies continue to shape governance, culture, and civic life today.
