What is the Constitution known for establishing?

The Constitution is known for establishing the framework for the federal government, which is integral to the functioning of the United States. It outlines the structure of government, including the legislative, executive, and judicial branches, and defines the powers and responsibilities of each. By doing this, it creates a system of checks and balances intended to prevent any one branch from becoming too powerful. This foundational document also delineates the relationship between the federal government and the states, as well as the rights of citizens.

The other options do not accurately describe the Constitution's purpose or significance. For instance, the establishment of a monarchy contradicts the principles of democracy and popular sovereignty that the Constitution supports. While the Bill of Rights is an essential component of the Constitution that guarantees individual freedoms, it is not the only focus of the document. Furthermore, while the Constitution does allow for state sovereignty, it ultimately establishes a stronger federal government to unify the states under a common legal framework.
