Answer:
The confederal form of government, which was tried under the Articles of Confederation, proved to be ineffective and inadequate in addressing the needs of the newly formed United States of America. The Articles of Confederation established a weak central government that lacked the power to regulate commerce, levy taxes, or enforce laws. As a result, the states had a great deal of autonomy, but they often acted in their own self-interest and did not cooperate with each other or with the central government.
The weaknesses of the confederal system became apparent during the Revolutionary War, when the central government struggled to raise funds and resources to support the war effort. The federal government had to rely on voluntary contributions from the states, but many of them were unwilling or unable to contribute, which made it difficult for the central government to carry out its duties effectively.
In response to these challenges, the framers of the Constitution created a federal system of government that gave the central government more power and authority while still preserving the autonomy of the states. The federal government was given the power to regulate commerce, levy taxes, and enforce laws, which enabled it to address the needs of the nation as a whole and promote the general welfare. At the same time, the states retained a significant degree of autonomy and were able to govern themselves in areas that were not delegated to the federal government.
Overall, the shift from a confederal to a federal form of government in the United States was driven by the need to create a more effective and efficient system of government that could address the needs of the nation as a whole and promote the general welfare.
