The document provides an overview of the Articles of Confederation, the first constitution of the United States adopted in 1777. It established a weak central government with limited powers and a loose alliance of independent states. Key limitations included that each state had one equal vote in Congress, there was no president or national courts to enforce laws, and no national military to resolve conflicts between states. This structure proved problematic and led to conflicts between states, financial problems, and rebellions like Shays' Rebellion, demonstrating the need for a stronger national government, which led to the calling of the Constitutional Convention in 1787.
