Natural Rights and the Social Contract

Start before government exists, in what John Locke called the state of nature. People already have natural rights: life, liberty, and property, which belong to them simply because they are human, not because any ruler granted them. The problem is that in a state of nature nobody enforces those rights. Anyone strong enough can take your land or your life, and you have no higher authority to appeal to. So people agree with each other, by consent, to form a government whose one job is to protect the rights they already had. That agreement is the social contract.

Three ideas stack on top of each other here. Natural rights come first, existing before any government. Popular sovereignty comes next: since the people already hold rights and only they can hand over power, legitimate authority has to come from their consent, not from a king's bloodline or a conqueror's sword. Limited government follows from both: government only ever receives the narrow power needed to protect natural rights, so any power it uses beyond that purpose was never legitimately given to it.

No one actually signed this. The social contract is not a historical event or a physical document; it is a theory explaining what makes government authority legitimate in the first place. The founders used it to justify independence: if government exists only by consent and only to protect natural rights, a government that attacks those rights breaks its side of the deal. That is exactly the logic the Declaration of Independence borrows from Locke, and it sets up why the Constitution later splits and limits power so no single government can do what Britain did.
