Learnt something interesting today about the foundation of American political system based on the influence of Polybius

Quoting from other sources

The Romans designed a "mixed constitution" that balanced power among different social classes to prevent any single faction from seizing absolute control. The U.S. Constitution directly mirrors this tripartite division:

The Executive (Monarchical Element): In Rome, dual Consuls led the executive branch and commanded the military. In the U.S., this power is concentrated in a single President, but the concept of executive vetoes and term limits reflects Roman checks on executive power.

The Senate (Aristocratic Element): The Roman Senate represented the patrician class, offering seasoned, long-term political wisdom and oversight. The U.S. Senate was originally envisioned by the Framers to be a stabilizing, deliberative body insulated from short-term public passions.

The Assembly/Tribunes (Democratic Element): Roman popular assemblies and the Tribunes of the Plebs protected the common citizens and checked aristocratic overreach. In the U.S., the House of Representatives serves this function, remaining closely tied to the immediate will of the electorate.
