Constitution Day
September 17th is known as "Constitution Day”. On this date in 1787, after four months of discussion and debate, 39 delegates (out of 55) signed the U.S. Constitution.
Although the Constitution has long been a familiar topic in our history classes, there is still much to learn about the document, its development, and its continuing influence on American life.
Read and Understand the Constitution
The Constitution established the structure of our federal government, divided its power between three branches, and created a process for changing the document through amendments.
