In what year was the Constitution of the United States written?

The Constitution of the United States was written in 1787 during the Philadelphia Convention, where delegates from the states came together to address the weaknesses of the Articles of Confederation. The resulting document established a stronger federal government and included compromises that balanced the interests of both large and small states, as well as protections for individual rights.

The year 1776 is significant for the Declaration of Independence, which proclaimed the colonies’ separation from British rule, but it is not the year the Constitution was written. The year 1791 marks the ratification of the Bill of Rights, the first ten amendments to the Constitution, which ensured specific protections of individual liberties. The year 1801 pertains to the early years of Thomas Jefferson's presidency, well after the Constitution was established. Hence, 1787 is the correct answer.
