Final answer:
The Articles of Confederation were difficult to amend due to the requirement for unanimous consent from all states, thus leaving the national government with limited powers and unable to resolve major issues effectively. This led to the drafting of the Constitution, which provided a more practical amendment process.
Step-by-step explanation:
The government under the Articles of Confederation was largely ineffective due to its numerous limitations. One of the biggest issues was the lack of power given to the national government which made it difficult to address problems such as public finance, defense, and commercial relationships with other nations. Perhaps the most significant problem was the requirement that any amendment to the Articles needed unanimous consent from all the states.
Because of the high threshold for change, it was nearly impossible for the Confederation Congress to adapt and improve the government's structure. Despite the pressing needs to solve border issues and to have a functioning national defense, amending the Articles was a herculean task. The only solution became apparent in 1787, leading to the call for creating a stronger central government that eventually resulted in the drafting of the Constitution. This new governing document included a more realistic method for amendments, allowing for a two-thirds majority in Congress and three-quarters of state legislatures' approval rather than a unanimous decision.
