What year at the request of congress the states draft new constitutions based on the authority of the people?

In 1787, at the request of Congress, the states were urged to draft new constitutions based on the authority of the people. This initiative aimed to create stronger state governments following the weaknesses of the Articles of Confederation. The resulting state constitutions often emphasized popular sovereignty and individual rights. This movement laid the groundwork for the eventual adoption of the U.S. Constitution in 1789.
