Final answer:
The U.S. Constitution was influenced by beliefs in natural rights and separation of powers, which are reflected in its structure that includes distinct branches of government with checks and balances.
Step-by-step explanation:
Other beliefs that influenced the Constitution include natural rights and the concept of separation of powers. These ideas were incorporated into the Constitution in various ways. Natural rights, as espoused by John Locke, underpin the idea that people are entitled to life, liberty, and property. This concept is reflected in the Declaration of Independence and implicitly supported by the Constitution through its framework that aims to protect citizens' rights. Separation of powers was heavily influenced by Baron Montesquieu's writings, and the Constitution embodies this by establishing a government with executive, legislative, and judicial branches, each with distinct functions and checks and balances over the others.
The Constitution did not include other systems like Manifest Destiny, states' rights, feudalism, monarchy, mercantilism, or absolute monarchy in its core structure; instead, it focused on creating a federal republic that emphasized limited government and the protection of individual liberties.
