Why did the Philadelphia Constitutional Convention of 1787 initially call to amend the Articles of Confederation resulted in the ultimate creation of a new government?

The Philadelphia Constitutional Convention of 1787 was initially convened to amend the Articles of Confederation due to their inherent weaknesses, such as the lack of a strong central government and difficulties in regulating commerce or collecting taxes. However, as delegates gathered, they recognized that mere amendments would not suffice to address these systemic issues. Instead, they opted to draft an entirely new Constitution that established a stronger federal framework, ultimately leading to the creation of a new government designed to better balance power between the states and the national authority. This shift reflected a consensus that a more robust system was necessary to ensure stability and effective governance.
