Why Did the Constitution Replace the Articles of Confederation?

Ratified in 1781, the Articles were America's first national framework. Fresh from a war against a powerful central authority, the states deliberately kept the new government weak: it was essentially a league of independent states with a Congress that had very little real power.

• No power to tax — Congress could only request money from the states, which often didn't pay. War debts went unpaid.
• No power to regulate commerce — states taxed each other's goods and fought trade wars.
• No executive — there was no president to enforce the laws.
• No national court system — disputes between states had no reliable referee.
• Nearly impossible to act — passing major laws took 9 of 13 states, and any amendment required all 13.

In 1786–87, a group of debt-burdened farmers in Massachusetts, led by Daniel Shays, rose up against the courts. The national government had no army to respond, and the uprising frightened leaders into action. It became the clearest proof that the Articles couldn't keep order — and the push that brought delegates to Philadelphia.

There, in the summer of 1787, the Constitutional Convention abandoned the idea of merely revising the Articles and instead drafted an entirely new framework: the Constitution, with a government strong enough to tax, regulate trade, and enforce its laws — balanced by the separation of powers.
