When did the first Constitution became law?

The Constitution of the United States is the foundation of our American Government. It lays out the system of Government and the rights of the American people. The Constitution has three parts. The Preamble tells the purpose of the document and Government. The Articles set up how the Government is organized and how the Constitution can be changed. The Amendments are changes to the Constitution. The first ten Amendments are called the Bill of Rights.

In the early 1600s, the British king set up colonies in America along the Atlantic coast. People came to the colonies for many reasons; some wanted to make money, and others came to find religious freedom. By the 1700s there were 13 British colonies. But the colonists were unhappy about paying taxes without having any say in the laws that governed them. This would eventually lead to war between the Americans and the British in the American Revolutionary War (1775-1783).

Before the American Revolutionary War, each state had its own constitution. After the war ended, the states joined together to set up a Federal Government under the Articles of Confederation. The Articles turned out to be a weak system of government and this needed to be changed.

The Writing of the Constitution of the United States of America

Representatives from the states met at the Constitutional Convention of 1787. They debated about what should be included in the Constitution. Large states felt that they should have more representation in Congress, while small states wanted equal representation. The leaders created a bicameral legislative branch, which gave equal representation to each state in the Senate and representation based on population in the House of Representatives.

The Constitution also created an executive branch and a judicial branch to set up a system of checks and balances. All three branches would have power so no one branch could become more powerful than another. The Constitution was presented to the American public on September 17, 1787.

The Constitution is known as a living document because it can be changed, or amended. Since its ratification, or formal approval, it has only been changed 27 times. Although it has been amended over the years, the Constitution's basic form still exists today.

U.S. Constitution facts and figures:

  • The Constitution became law on June 21, 1788, when two-thirds of the states ratified it.
  • The 13 colonies later became the states of Connecticut, Delaware, Georgia, Maryland, Massachusetts, New Hampshire, New York, New Jersey, Virginia, North Carolina, Pennsylvania, Rhode Island, and South Carolina.

June 21, 1788: New Hampshire becomes the ninth and last necessary state to ratify the Constitution of the United States, thereby making the document the law of the land.

By 1786, defects in the post-Revolutionary War Articles of Confederation were apparent, such as the lack of central authority over foreign and domestic commerce. Congress endorsed a plan to draft a new constitution, and on May 25, 1787, the Constitutional Convention convened at Independence Hall in Philadelphia. On September 17, 1787, after three months of debate moderated by convention president George Washington, the new U.S. constitution, which created a strong federal government with an intricate system of checks and balances, was signed by 38 of the 41 delegates present at the conclusion of the convention. As dictated by Article VII, the document would not become binding until it was ratified by nine of the 13 states.

Beginning on December 7, five states—Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut—ratified it in quick succession. However, other states, especially Massachusetts, opposed the document, as it failed to reserve undelegated powers to the states and lacked constitutional protection of basic political rights, such as freedom of speech, religion, and the press. In February 1788, a compromise was reached under which Massachusetts and other states would agree to ratify the document with the assurance that amendments would be immediately proposed. The Constitution was thus narrowly ratified in Massachusetts, followed by Maryland and South Carolina. On June 21, 1788, New Hampshire became the ninth state to ratify the document, and it was subsequently agreed that government under the U.S. Constitution would begin on March 4, 1789. In June, Virginia ratified the Constitution, followed by New York in July. 

On September 25, 1789, the first Congress of the United States adopted 12 amendments to the U.S. Constitution—the Bill of Rights—and sent them to the states for ratification. Ten of these amendments were ratified in 1791. In November 1789, North Carolina became the 12th state to ratify the U.S. Constitution. Rhode Island, which opposed federal control of currency and was critical of compromise on the issue of slavery, resisted ratifying the Constitution until the U.S. government threatened to sever commercial relations with the state. On May 29, 1790, Rhode Island voted by two votes to ratify the document, and the last of the original 13 colonies joined the United States. Today the U.S. Constitution is the oldest written constitution in operation in the world.
