Answer:
By 1786, Americans realized that the Articles of Confederation, the first written constitution of the United States, had to be changed as, according to the Articles, Congress had no rights regarding the control of domestic affairs, such as taxation or commerce regulation. It depended on the financial help of the states, lacking money to pay soldiers for their service in the Revolutionary War or repay foreign loans. By 1786, the US was bankrupt. In 1787 a decision was made to write a new constitution, which was adopted the same year in Philadelphia.
