Is it true the constitution was written quickly in a few days?

No, the U.S. Constitution was not written quickly in a few days. The Constitutional Convention convened in Philadelphia in May 1787 and took several months to draft the document, culminating in its completion in September of that year. The delegates engaged in extensive debates and revisions, reflecting the complexity of the issues and the need for compromise among the states. The final document was signed on September 17, 1787, after thorough discussions and deliberations.
