What do you consider the two most important changes made from the articles to the constitution?

Two of the most important changes made from the articles to the Constitution include the establishment of a stronger federal government and the creation of a system of checks and balances. Under the Articles of Confederation, the federal government lacked the power to tax and regulate interstate commerce, leading to inefficiencies and instability. The Constitution addressed these issues by granting Congress the authority to levy taxes and regulate trade, while the separation of powers among the legislative, executive, and judicial branches ensured that no single entity could dominate the government. This framework enhanced both governance and protection of individual rights.
