Written in 1787, ratified in 1788, and in operation since 1789, the United States Constitution is the world's longest surviving written charter of government. Its first three words—"We the People"—affirm that the government of the United States exists to serve its citizens. For over two centuries the Constitution has remained in force because its framers wisely separated and balanced governmental powers to safeguard the interests of majority rule and minority rights, of liberty and equality, and of the federal and state governments. Since 1789 the Constitution has evolved through amendments to meet the changing needs of a nation now profoundly different from the 18th-century world in which its creators lived.
The United States enjoys a representative form of government, shaped by three separate branches as established in the Constitution:
A system of checks and balances, which the Constitution also sets forth, limits the powers of each branch.
Article I of the Constitution created and defined the United States Congress, granting to the two houses of the legislative branch such powers as the ability to collect taxes, coin money, raise and support an army, declare war, establish post offices, create patent laws, and establish a federal judicial system. It gave to the Senate the exclusive right to provide advice and consent to the president on treaties and nominations, and the sole power to try, and to remove from office, an impeached government official.
More than two centuries after its ratification, the United States Constitution remains a vital and living document, strengthened by amendments, serving as both guide and protector of U.S. citizens and their elected officials. It has survived civil war, economic depressions, assassinations, and even terrorist attacks, to remain a source of wisdom and inspiration.
The creation of the U.S. Constitution depended upon the knowledge, experience, and dedication of its framers, just as its endurance depends upon the knowledge and experience of each succeeding generation of Americans. For this reason, it is important for us to learn and understand the governing principles of our nation, set forth in the Constitution.
To encourage all Americans to learn more about the Constitution, Congress in 1956 established Constitution Week, to begin each year on September 17, the date in 1787 when delegates to the Convention signed the Constitution. In 2004 Senator Robert C. Byrd of West Virginia included key provisions in the Consolidated Appropriations Act of Fiscal Year 2005 designating September 17 of each year as Constitution Day and requiring public schools and government offices to provide educational programs to promote a better understanding of the Constitution.
