American leaders learned from various forms of government, including ancient Greece and Rome, Enlightenment thinkers, and their own experiences under British rule. These influences shaped the principles that can be found in the United States Constitution.

1. Ancient Greece and Rome:
- The concept of democracy from ancient Athens influenced the idea of popular sovereignty, where power rests with the people. This is evident in the Constitution through the system of representative government and the election of leaders by the people.
- The idea of a republic, inspired by the Roman Republic, helped shape the structure of government with a balance of power and the separation of powers, which is reflected in the Constitution's framework of three branches of government.

2. Enlightenment Thinkers:
- The Enlightenment period, particularly the ideas of philosophers such as John Locke, Montesquieu, and Rousseau, greatly influenced American thinking. Locke's theory of natural rights, including life, liberty, and property, inspired the inclusion of fundamental rights in the Constitution, such as the Bill of Rights.
- Montesquieu's theory of separation of powers influenced the creation of the three branches of government, ensuring a system of checks and balances to prevent the abuse of power.
- Rousseau's concept of the social contract, where individuals consent to be governed, is reflected in the Constitution's emphasis on popular sovereignty and the consent of the governed.

3. British Rule and Colonial Experience:
- The American colonists experienced firsthand the flaws and injustices of British rule. They learned the importance of protecting individual rights and limiting the power of the central government.
- The British legal tradition, including the Magna Carta and English Bill of Rights, influenced the development of principles such as due process, trial by jury, and protection against unreasonable searches and seizures. These concepts were incorporated into the Constitution, primarily in the Bill of Rights.

In summary, American leaders drew inspiration from various sources, including ancient Greece and Rome, Enlightenment thinkers, and their own experiences under British rule. These influences shaped key principles in the Constitution, including popular sovereignty, a system of checks and balances, protection of individual rights, and limited government power.
