the Articles of Confederation,the U.S. Constitution or both
"One branch of government (legislative)" fits in both the Articles of Confederation and the U.S. Constitution.
In the Articles of Confederation, the legislative branch was called the "Congress of the Confederation" and had the power to make laws and govern the nation. However, the Congress of the Confederation had limited powers and the states retained most of their sovereignty.
In the U.S. Constitution, the legislative branch is also established and is called the "Congress." It is made up of two houses, the Senate and the House of Representatives. The Congress has the power to make laws, levy taxes, regulate commerce, and more. The U.S. Constitution strengthened the legislative branch compared to the Articles of Confederation, giving it more authority and providing a more centralized government.
