Why did the amendment and ratification process change from unanimous to a majority vote?

The amendment and ratification process changed from requiring unanimous consent to a majority vote to facilitate a more practical and efficient governance structure. The Founding Fathers recognized that achieving unanimous approval would be nearly impossible, given the diverse interests and opinions of the states. By allowing amendments to be ratified by a majority, the process became more accessible, enabling necessary changes to the Constitution while still maintaining a level of consensus among the states. This shift aimed to balance flexibility with stability in the constitutional framework.
