When crafting the Constitution, one of the central concerns of the Founding generation was how best to control government power. With the new Constitution, the Framers looked to strike an important balance—creating a new national government that was more powerful than the one that came before it while still protecting the American people’s most cherished liberties. They settled on a national government with defined but limited powers. Instead of placing authority in the hands of a single person (like a king), a small group of people (like an aristocracy), or even the whole people (like a direct democracy), the Framers divided power in two ways. At the national level, the Framers divided power between the three branches of government—the legislative branch, the executive branch and the judicial branch. This process of dividing power between different branches of government is called the separation of powers. From there, the Framers further divided power between the national government and the states under a system known as federalism. In this module, students will explore the key functions of the different parts of government and the role that the Constitution plays in controlling government power.
