What were the Articles of Confederation, why were they created, and what problems did they hold?

The Articles of Confederation and Perpetual Union were a group of systemic principles adopted jointly by the thirteen former British colonies in North America, which worked as the first written constitution of the United States and entered into force on March 1, 1781.

The Articles were devised by the Founding Fathers as a set of common rules for all states, which would allow an effective defense of the nation in case of external attacks, as well as facilitate commercial exchanges between states.

The Articles of Confederation were replaced by the Constitution of the United States on March 4, 1789, given that they were proven to be ineffective to organize a strong and effective national government in the face of external threats, capable of organizing the nation economically and politically.
