The framers of the Constitution feared too much centralized power, adopting the philosophy of divide and conquer. At the national level, they created three different branches of government to administer three different types of power. The legislative branch made the laws through a Congress of two houses, the Senate and the House of Representatives. The executive branch enforced the laws through a president, vice president, and numerous executive departments such as Treasury and State. And the judicial branch interpreted the laws through a Supreme Court and other lower courts. In the words of James Madison: “The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may justly be pronounced the very definition of tyranny."
