Natural rights, the social contract, and why power is split on purpose.
Why people create government
A government is the system a community uses to make rules, settle fights, and protect people. Without rules that everyone has to follow, the strong can take from the weak and nobody’s property or safety is secure.
The Founders did not invent this worry. English and European writers had already argued that people agree to be governed so they can live safely together. That agreement is the social contract: people give a government some power, and the government must protect their rights in return.
Remember: Social contract = people consent to government so their rights can be protected.
John Locke and natural rights
John Locke said people are born with natural rights that no king invented: life, liberty, and property. Government exists to protect those rights. If a government breaks the contract and becomes a threat, the people may change it.
Thomas Jefferson rewrote Locke’s list in the Declaration of Independence as “life, liberty, and the pursuit of happiness.” Those rights are unalienable — they cannot be taken away just because a ruler says so.
Remember: Locke: life, liberty, property. Declaration: life, liberty, and the pursuit of happiness.
Montesquieu and split power
Baron de Montesquieu studied governments and warned that liberty dies when one person or group holds every kind of power. He argued for separation of powers: one part makes laws, another carries them out, another judges disputes.
The U.S. Constitution copies that idea. Congress legislates, the president executes, and the courts interpret. Each branch can also slow the others down. That second idea is checks and balances.
Other Enlightenment pieces you will see on the EOC
Rule of law means even leaders must obey the law. Due process means the government must follow fair procedures before it takes life, liberty, or property.
Self-government means people have a say, usually by electing representatives. A republic is a form of government where citizens elect people to make laws for them. The United States is a constitutional republic, not a pure democracy where everyone votes on every law.
Remember: Republic = elected representatives. Separation of powers ≠ checks and balances. They work together, but they are not the same phrase.
