What is the central idea in the bill of rights

The US Bill of Rights exists due to the decision of the framers of the constitution in 1783 to codify (make law) a specific list of the most important freedoms which must be safeguarded for the United States of America to begin its life as a constitutional democracy. Therefore, the first 10 amendments to the US Constitution became known as the US Bill of Rights.

The central idea was the rights to a citizen of a country and the purpose was to protect those rights from infringement and public officials and private citizens.
