A tiny story behind the number

Not everyone at the convention was happy with the final document. A few influential delegates refused to sign, arguing that it gave too much power to the new central government and lacked a bill of rights. Their objections helped fuel later debates that led to the Bill of Rights, which was added soon after ratification.

In a way, the fact that 39 signed and several refused shows that the Constitution was born out of compromise, disagreement, and intense debate—not unanimous cheerleading.

TL;DR:

  • 55 delegates participated at some point in the Constitutional Convention.
  • 39 delegates signed the Constitution in the end.
