What principles present in the Articles still are present in the Constitution?

Several principles from the Articles of Confederation are retained in the U.S. Constitution, including the concept of federalism, which allows for a division of power between national and state governments. Additionally, the Articles' emphasis on the importance of a legislative body is reflected in the Constitution’s establishment of a bicameral Congress. The principle of representation, though significantly refined, also carries over, ensuring that states have a voice in the federal government. However, the Constitution strengthens the federal government’s authority and ability to tax, which was a limitation under the Articles.
