What is the purpose of the constitutional congress meeting in 1787?

The Constitutional Convention of 1787 was convened to address the weaknesses of the Articles of Confederation and to create a stronger federal government. Delegates from twelve of the thirteen states gathered in Philadelphia to draft a new constitution that would establish a system of checks and balances, protect individual rights, and ensure a more effective governance structure. The outcome of the meeting was the United States Constitution, which laid the foundation for the country's political system.
