Why did the US adopt the Constitution?

The United States adopted the Constitution in 1787 to establish a stronger and more effective federal government, addressing the weaknesses of the Articles of Confederation. The framers aimed to create a system that balanced power between the national and state governments while protecting individual rights. The Constitution also sought to promote unity among the states and ensure a framework for governance that could adapt to future challenges. Ultimately, it was ratified to provide stability and order in the newly formed nation.
