To address the question, we will create a graphic organizer with two columns: "Civilization" and "Contribution." This will help categorize the groups that settled in the Italian peninsula and their contributions to Roman culture.
| Civilization | Contribution |
|--------------|--------------|
| Etruscans | The Etruscans significantly influenced Roman culture, particularly in architecture, religion, and governance. They introduced the arch, which became a staple in Roman engineering and architecture. The Etruscans also contributed to the development of Roman religious practices and rituals, as well as the organization of the Roman military. |
| Greeks | The Greeks contributed to Roman culture through their art, literature, and philosophy. The Romans adopted the Greek pantheon of gods, albeit with different names, and were heavily influenced by Greek sculpture and architecture. Greek philosophy, particularly the works of Plato and Aristotle, also played a crucial role in shaping Roman intellectual life. |
| Samnites | The Samnites, an Italic tribe, influenced Roman military tactics and organization. The Romans adopted certain elements of Samnite warfare, such as the use of the manipular formation, which was crucial in the development of the Roman legion. Additionally, the Samnites contributed to the cultural and linguistic diversity of the Roman Republic. |
These groups, among others, played a vital role in shaping the early Roman civilization, contributing to its development in various aspects such as architecture, religion, military tactics, and cultural practices.
