Why was it crucial to add the bill of rights to the us constitution?

The Bill of Rights of the United States is the collective name given to the first ten Amendments to the Constitution, approved on December 15, 1791.

It was an answer to calm the fears of antifederalist groups, some of them influential opponents of the Constitution, and prominent members of the Philadelphia Convention, who argued that it failed to defend the basic principles of human freedom. These amendments guarantee a series of personal freedoms, limit the power of the government in the judicial processes; and reserve some faculties to the states and the people. Originally the modifications applied only to the federal government, however, most were subsequently applied to the government of each state through the Fourteenth Amendment through a process known as incorporation.

The Bill of Rights had little judicial impact for the first 150 years of its existence, but it was the basis for many of the decisions of the Supreme Court of the 20th and 21st centuries. The Bill of Rights plays a central role in US law and its government, and continues to be a fundamental symbol of the nation's freedom and culture.
