The roots of the United States Government derive from:
1. England/Great Britain: The United States Government's origins can be traced back to England and the British political system. Concepts like the rule of law, separation of powers, and the idea of representative government influenced the development of the U.S. system.
2. France: The United States Government was also influenced by French philosophers such as Montesquieu and Rousseau. Their ideas on democracy, individual rights, and the social contract helped shape the principles underlying the U.S. Constitution.
These are the main sources from which the roots of the United States Government derive. France and England/Great Britain played significant roles in shaping the political philosophy and institutions that form the basis of the U.S. system of government.
