Answer:
Alexander Hamilton used the constitutional idea advocating the creation of a strong federal government with authority to levy taxes and gather an army. It also included the separation of powers in three branches: Executive, Legislative and Judicial.
Explanation:
In July 1782 Hamilton was appointed to the Congress of the Confederation as a representative of New York for the term beginning in November 1782. Prior to his appointment to Congress, Hamilton was already publicly criticizing the institution. While a member of George Washington's company, Hamilton did not like the decentralized nature of the Continental Congress during the war, largely because it relied on voluntary state funding. According to the Articles of Confederation, Congress could not levy taxes or demand money from states. The lack of a stable source of funding had made it difficult to obtain the necessary supplies from the Continental Army to pay its soldiers. During the war, and some time after it was over, Congress obtained its funding through the King of France, the financial assistance requested from the various states (which often could not or would not contribute) and from European loans.
Unhappy with central government weakness, Hamilton drafted an appeal for a review of the Confederacy Articles at Princeton. This resolution contained many of the features of the future US Constitution, including a strong federal government with authority to levy taxes and raise an army. It also included the separation of powers in three branches: Executive, Legislative and Judicial.
