Incorporation of the Bill of Rights

Incorporation, in U.S. law, is the process by which American courts have applied portions of the U.S. Bill of Rights to the states. Prior to 1925, the Bill of Rights was held only to apply to the federal government. Under the incorporation doctrine, most provisions of the Bill of Rights now also apply to the state and local governments.

Prior to the ratification of the Fourteenth Amendment and the development of the incorporation doctrine, the Supreme Court in 1833 held in Barron v. Baltimore that the Bill of Rights applied only to the federal, but not any state governments. Even years after the ratification of the Fourteenth Amendment, the Supreme Court in United States v. Cruikshank (1876) still held that the First and Second Amendment did not apply to state governments. However, beginning in the 1920s, a series of United States Supreme Court decisions interpreted the Fourteenth Amendment to "incorporate" most portions of the Bill of Rights, making these portions, for the first time, enforceable against the state governments.

The doctrine of incorporation has been traced back to either Chicago, Burlington and Quincy Railroad v. City of Chicago (1897) in which the Supreme Court appeared to require some form of just compensation for property appropriated by state or local authorities (although there was a state statute on the books that provided the same guarantee) or, more commonly, to Gitlow v. New York (1925), in which the Court expressly held that States were bound to protect freedom of speech. Since that time, the Court has steadily incorporated most of the significant provisions of the Bill of Rights.
