The original purpose of the Constitutional Convention of 1787 was officially to revise and amend the Articles of Confederation so the national government could function more effectively.

Core purpose in 1787

  • Congress and the states agreed to send delegates to Philadelphia to “revise” the Articles of Confederation, not to write a brand‑new constitution.
  • Leaders wanted to fix problems like the weak central government, inability to tax, and difficulty coordinating national policy under the Articles.

Problems they wanted to fix

  • The national government could not levy taxes directly, making it nearly impossible to pay debts or fund a standing army.
  • Events like Shays’ Rebellion highlighted how fragile and ineffective the Confederation system was at maintaining order and economic stability.

What the convention actually did

  • Although called just to amend the Articles, the delegates quickly moved toward drafting an entirely new Constitution that created a stronger federal government.
  • The resulting Constitution shifted major powers—taxation, defense, and regulation of commerce—to a national government, while still preserving powers for the states.

Bigger goals behind the meeting

  • Many delegates hoped to “form a more perfect union,” create a government strong enough to provide defense and economic stability, yet restrained enough to protect liberty.
  • The convention thus became a turning point, transforming a loose confederation of states into a new constitutional system with separate branches and a stronger, but limited, central authority.

TL;DR: The Constitutional Convention of 1787 was called to repair the failing Articles of Confederation, but it ended up writing a completely new Constitution that established a stronger national government.
