Why was the constitutional convection necessary?

The Constitutional Convention was necessary to address the weaknesses of the Articles of Confederation, which created a weak federal government unable to effectively manage issues such as interstate commerce, taxation, and national defense. Delegates recognized the need for a stronger central government to ensure stability and unity among the states. Additionally, the convention aimed to create a framework that balanced power between state and federal authorities while protecting individual rights. Ultimately, it resulted in the drafting of the U.S. Constitution, establishing a more effective and lasting governmental structure.
