Final answer:
The success of the U.S. Constitution's ratification depended crucially on the support from Virginia and New York, due to their size and influence. Virginia ratified the Constitution after the promise of a Bill of Rights, whereas New York's acceptance was vital for achieving widespread support and legitimacy.
Step-by-step explanation:
The Ratification of the U.S. Constitution
Although the Constitution officially went into effect after nine states ratified it, political leaders knew that it would not succeed without the support of Virginia and New York, the most populous and influential states at the time. The ratification process was met with resistance from those who feared a strong central government, associated with increased taxes and the potential to be drawn into wars, reminiscent of British tyranny. In particular, the lack of a Bill of Rights became a sticking point during the ratification debates.
Virginia, critical to the success of the Constitution, was deeply divided, and the ratification contest was so close it continued even after the technical number for ratification had been reached elsewhere. The assurances provided that a Bill of Rights would be added helped secure Virginia's approval.
Ultimately, the acceptance of the Constitution by New York and Virginia was pivotal for the broader adoption and successful implementation of the document, ensuring the formation of a more unified and enduring United States.
