Who came up with the idea of creating a new system of government rather than trying to fix the Articles of Confederations?

The idea of creating a new system of government instead of amending the Articles of Confederation was largely championed by Alexander Hamilton and James Madison. At the Constitutional Convention in 1787, they argued for a stronger federal government to address the weaknesses of the Articles. Their advocacy led to the drafting of the U.S. Constitution, which established a more robust and effective government framework.
