Step-by-step explanation:
The conflict faced by the United States from 1777 to 1787, under the Articles of Confederation, was multifaceted. Predominantly, it stemmed from the inherent tensions between the desire for a strong, central federal government and the fears of losing self-governance cherished by independent states. The Articles provided for a federal-style government but one so weak that the nation struggled to conduct basic functions such as trade negotiations, tariff impositions, and appropriations to cover war debt.
The inadequacies of the Articles became palpably clear with events like Shays' Rebellion, highlighting serious economic and political dysfunction. Consequently, leaders recognized the need for a stronger, more effective national government, leading to the drafting of the Constitution during the Philadelphia Convention, thus radically altering the existing confederal government. James Madison and Alexander Hamilton, notable Federalists, pushed for this new constitution that would create a solid foundation for the young nation.The primary conflict from 1777 to 1787 in the United States revolved around the struggle for a balanced power distribution between the state governments and a central federal government, culminating in the replacement of the weak Articles of Confederation with the stronger U.S. Constitution.
