In what year was the Constitution written?

The Constitution of the United States was drafted in 1787 during the Constitutional Convention held in Philadelphia. This gathering was called to address the weaknesses of the Articles of Confederation, the first governing document of the United States. The result was a new framework for government that established the system of checks and balances and laid the foundation for a strong federal government.

The year 1789 marks when the Constitution went into effect after being ratified by nine of the thirteen states, while 1776 is significant as the year of the Declaration of Independence, which announced the colonies' intent to separate from British rule. The year 1791 is important because it is when the Bill of Rights, the first ten amendments to the Constitution, was ratified, but it does not pertain to the original drafting of the Constitution itself. Thus, the correct choice, 1787, accurately reflects the year the Constitution was written.
