What Memories of which past experience caused the founding fathers to include the constitution a system of separation of powers?

The Founding Fathers were influenced by their experiences under British rule, particularly the concentration of power in the monarchy, which often led to tyranny and abuse of authority. They recalled the lack of representation and the arbitrary decisions made by a singular ruler, prompting them to establish a system of separation of powers in the Constitution. This framework was designed to prevent any one branch of government—executive, legislative, or judicial—from becoming too powerful, ensuring a system of checks and balances that would protect individual liberties and promote fair governance.
