U.S. Constitution (1787)

The Constitution — the OG rulebook. Signed in 1787, it basically said, “Okay, let’s try this whole democracy thing.” It built the playbook for every American argument since — separation of powers, checks and balances, and a government that’s equal parts genius and chaos. Some call it timeless, others call it outdated DLC. Either way, every debate, law, and Supreme Court drama traces back to this bad boy.
