The American constitution established America’s national government and fundamental laws, and guaranteed certain basic rights for its citizens.
It was signed on September 17, 1787, by delegates to the Constitutional Convention in Philadelphia.
The transcription of the Constitution, as it was inscribed by Jacob Shallus on parchment reads, “We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.”
“The Constitution’s 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.” — United States Senate
According to constitutional legal scholars and historians, “the written Constitution is fundamental law. It can change only by an extraordinary legislative process of national proposal, then state ratification.”
