1787. The US Constitution has been adopted
225 years ago, on September 17, 1787, the constitutional convention in Philadelphia approved the current edition of the US Constitution. From the Confederation of the States, America has turned into a federation of the United States of America, in which the States, nevertheless, retained wide autonomy. This was the world's first constitution in the modern sense of the word. It consists of seven articles, subsequently supplemented by twenty seven amendments.
