Separation Of Government Power

Separation of powers was an idea accepted by all sides of the writers in the American constitution, though it's straight to the point meaning remained unclear, at least until its famous publication in the Federalist, the protection of the Constitution written by Alexander Hamilton, James Madison, and John Jay. The confusion over the meaning of separation of powers arose mainly from the status of the executive’s power, and how powerful it should be. Such a weak executive office couldn’t balance the power of the legislature, however. So they write up Article 2 to balance and strengthen the executive office. The "federative" power, as John Locke named it. While this federative power was theoretically distinguishable from the executive, in practice
The Constitution is the place where it states, clearly and explicitly, which powers we choose to give, and which powers we refuse to give. The Article IV created a strong national government that was powerful enough to take care of business, but also let states run themselves without interference from the government. In old fashioned monarchies, they held all powers of government, the power to make the law, the power to enforce the law, and the power to judge the law with no checks or balances. So when they designed the Constitution of the United States, the Framers insisted for the separation of powers to keep the government in check .The Framers believed the most important action in preventing tyranny in America was to divide the key powers of government amongst the three branches. They could have stopped there, leaving it up to the officials of the three branches to figure out how to defend their own powers and limit the powers of the others. But that might have led to a conflict between the branches. So the Framers carefully constructed a system of articles of seven divisions, that provided specific power to allow each of the branches of government equal
Instead they try to avoid such conflicts by monitoring their own policies before ending up in a pickle. Often enough, the mere threat of a veto is enough to get Congress to alter any bill or law to make it good for the president. Or the mere threat of Congress refusing to push military effort is enough to force the president to build up public support before intervening abroad. Or the mere threat of Senate disapproval may be enough to prevent the president from nominating a judge to the Supreme Court.
The last important part of America's system of limited government is the concept of federalism. In a federal system, some key powers are held by national government while others are forfor the various states government.

The American federalist system existed way before the draft of the Constitution. At the time of the Constitutional Convention, when there were already 13 states that had become accustomed to wielding a huge amount of power in managing their own affairs. They weren't going to choose give up all their power, in order to give all their powers to one united national government.

Furthermore, the Revolution of America had been, a revolt against a very distant and powerful central government. Why would the Writers, and signers of the Constitution want to recreate such a potential tyrannical
