Happy 235th birthday to the Constitution! Constitution Day marks the day the founders signed the new U.S. Constitution in Philadelphia.
The United States Constitution is one of the most well known constitutions in the world, and is the supreme law of the United States of America. It came into force in 1789, following its initial ratification in June of 1788. Since its implementation, the U.S. Constitution has been amended 27 times. The first 10 Amendments, collectively referred to as the "Bill of Rights", made provisions for protections of individual freedoms and met the need for equal justice, all the while curbing the powers of the government in certain cases. The majority of the remaining amendments have focused on the expansion and protection of civil rights.
