What significant event occurred at the Constitutional Convention?

The Constitutional Convention, held in Philadelphia in 1787, was a pivotal moment in American history where delegates from the thirteen original states gathered with the primary purpose of addressing the weaknesses of the Articles of Confederation. The most significant outcome of this gathering was the creation of the United States Constitution. This foundational document outlined the structure of the federal government, established the separation of powers among the legislative, executive, and judicial branches, and provided a framework for how the government would operate.

Unlike the Bill of Rights, which was added later as the first ten amendments to the Constitution to ensure the protection of individual liberties, the actual writing and drafting of the Constitution itself took place during this convention. The other events mentioned, such as the ratification of the Declaration of Independence and the election of the first president, occurred at different times and were not the focus of the Convention. Therefore, the correct answer is that the Constitution was written during the Constitutional Convention, marking a crucial step in the establishment of the United States as a democratic republic.
