What characteristics and concepts of the Roman Republic are present in the structure of American government? Answer quick for brainliest!

The Roman concept of the citizen evolved during the Roman Republic and changed significantly during the later Roman Empire. After the Romans freed themselves from the Etruscans, they established a republic, and all males over 15 who were descended from the original tribes of Rome became citizens. Citizens of Rome distinguished themselves from slaves and other noncitizens by wearing a toga; most wore a white toga. During the Empire, each emperor wore a purple toga to distinguish himself as the princeps, or "first citizen."
