Why was a constitutional convention called in 1776?

A constitutional convention was called in 1776 primarily to address the need for a new governing framework for the American colonies seeking independence from British rule. The existing Articles of Confederation proved inadequate in effectively managing the newly formed nation, leading to issues such as economic instability and lack of centralized authority. Delegates aimed to create a stronger, more cohesive government that would protect individual rights and promote unity among the states. This resulted in the drafting of the United States Constitution, which established a federal system of governance.
