Answer: checks and balances
Explanation:
The authors of the U.S. Constitution created a system based on the ideas of Polybius, Montesquieu, William Blackstone, and John Locke.
The system of checks and balances is part of the division of power between the three branches of the U.S. government (legislative, executive, judicial). Several controls and limitations were established on each branch to assure that neither would grab too much power.
