Final answer:
The state of New Harmony is concerned about unfair taxation, lack of representation, and oppressive laws, reflecting the historic need for stronger governance as seen in Shay's Rebellion and the subsequent creation of the U.S. Constitution.
Step-by-step explanation:
In the state of New Harmony, the situation causing concern and the need for a declaration of independence is unfair taxation, lack of representation, and oppressive laws. This situation echoes historical events such as Shay's Rebellion, where issues like the high taxation of farmers, inability to use farm goods as payment for debts and taxes, and economic difficulties leading to insurrections underscored the weakness of the government under the Articles of Confederation. It highlighted the need for a stronger national government that could maintain peace and harmonize relations within and among the states. Leaders such as George Washington, James Madison, and Alexander Hamilton advocated for a new system that eventually led to the drafting of the U.S. Constitution.
