Mukoma Masimba agrees 100% with Madison that: “The truth is that all men having power ought to be mistrusted.”

History of the Separation of Powers

Founding Fathers like James Madison knew all too well—from hard experience—the dangers of unchecked power in government. As Madison himself put it, “The truth is that all men having power ought to be mistrusted.”

Therefore, Madison and his fellow framers believed in creating a government-administered both over humans and by humans: “You must first enable the government to control the governed; and in the next place, oblige it to control itself.”

The concept of separation of powers, or “trias politics,” dates to 18th century France, when social and political philosopher Montesquieu published his famed “The Spirit of the Laws.” Considered one of the greatest works in the history of political theory and jurisprudence, “The Spirit of the Laws” is believed to have inspired both the United States Constitution and France’s Declaration of the Rights of the Man and of the Citizen.

The model of government conceived by Montesquieu had divided the political authority of the state into executive, legislative, and judicial powers. He asserted that ensuring that the three powers operate separately and independently was the key to liberty.

In the American government, these three branches, along with their powers, are:

• The legislative branch, which enacts the nation’s laws
• The executive branch, which implements and enforces the laws enacted by the legislative branch
• The judicial branch, which interprets the laws in reference to the Constitution and applies its interpretations to legal controversies involving the laws

So well-accepted is the concept of the separation of powers that the constitutions of 40 U.S. states specify that their own governments be divided into similarly empowered legislative, executive, and judicial branches.
