Final answer:
The Founding Fathers adapted the Roman concept of a republic, where elected representatives govern, along with the separation of powers in government to create the political system of the United States. This illustrates the influence of Roman contributions, and Enlightenment ideals on America's foundation.
Step-by-step explanation:
One significant Roman contribution to political theory that was adapted by the founding fathers of the United States was the concept of a republic. In Ancient Rome, citizens had the power to elect leaders to make governmental decisions, which can be seen reflected in the U.S. system where a government of elected representatives makes decisions on behalf of the people. The Founding Fathers also adopted Roman principles on the separation of powers in government and were greatly influenced by Enlightenment philosophers such as John Locke and Montesquieu.
The idea that only landowners should vote and the emphasis on civic virtue are other aspects carried over from Roman tradition to the U.S. political system. American political architecture also conveys the influence of Roman and Greek styles, which underscores the deep-rooted connection with classical republicanism. This rich blend of ancient and Enlightenment ideas is foundational to the political principles of the United States and continues to inform its citizenship expectations and democratic practices today.
