The Articles of Confederation was the United States' first constitution. Proposed by the Continental Congress in 1777, it was not ratified until 1781.
They were only supposed to propose amendments to the. Articles of Confederation. Official approval, or ratification, of an. entirely new constitution was doomed if all 13 states had to approve. it as the Articles required. To improve the odds of ratification, the del-. egates arbitrarily decided to change the rules.
