What is Constitution Day – History & Constitution Day Activities


Celebrated on Constitution Day, also known as Constitution and Citizenship Day, it honors the document that guarantees Americans their essential rights.

Since its ratification in 1787, the Constitution of the United States has served as the basis for all American laws.


To prevent the abuses of power to which they felt subjected under the British monarchy, the Founding Fathers wrote the Constitution with care, distributing power among three branches of government. The Constitution describes the powers of government, the limitations of those powers, and the rights of citizens. It also describes an amendment process to make changes in the future.

History of Constitution Day


After the American Revolution liberated the American colonies from British rule, the Founding Fathers wanted to ensure that the new government could not abuse its power. At the Constitutional Convention of 1787, delegates from twelve of the thirteen new states met to draft the document that would serve as the basis for all future American laws.


The Constitution requires three branches of government with equal powers, creating a system commonly known as “checks and balances.” Each branch has the power to mitigate the others. Powers not assigned to one of the three branches are left to the individual states.

Delegates to the Convention had two options for setting the framework for the new legislative branch. The Virginia Plan, predictably supported by larger states, called for population-based representation. The competing New Jersey Plan called for equitable representation for each state. The two-house solution known as the Great Compromise combines aspects of both plans and is still in use today.

The Constitution also describes the responsibilities and powers of the judiciary and executive, how the president is chosen, and other essential details.

The Founding Fathers recognized that society evolves and that the Constitution would require a mechanism to make changes. However, they wanted to ensure that the changes required the agreement of a large number of states. To modify the Constitution, a proposed amendment must be ratified by three-quarters of the states.

In 1940, Congress and the President passed a resolution creating “I Am an American Day,” which is celebrated on the third Sunday in May. In 1952, the holiday was renamed “Constitution Day” and moved to September 17, the day in 1787 that the Constitution was signed. More than 50 years later, in 2004, Congress changed the name of the holiday back to Constitution Day¬†and Citizenship Day.

  1. Thomas Jefferson never signed it
    Some very important Founding Fathers never signed the Constitution. Thomas Jefferson, for example, was in Paris serving as an ambassador to France.
  2. “Pennsylvania” is misspelled at the top
    In the list of signatories, Pennsylvania is written with a single “N”.
  3. The right to vote is not defined
    Because the Constitution did not establish rules about who can vote, minority groups have won the vote through subsequent amendments.
  4. Less than 1% of constitutional amendments pass
    Of the 11,600 proposed amendments, only 27 have been ratified, making the probability of passing an amendment 0.23%, or rounded down, 0.
  5. Benjamin Franklin had to be carried
    The elderly statesman had to be transported to and from Convention meetings due to poor health and needed help signing the document.
