After the passage of the Fourteenth Amendment, the Supreme Court, through a string of cases, found that the Due Process clause of the Fourteenth amendment included applying parts of the Bill of Rights to States (referred to as incorporation). A lot of contention surrounds whether the Fourteenth Amendment should incorporate any substantive rights, with opinions from Supreme Court justices ranging from complete to no incorporation ( see
substantive due process ). Rather than find that the Due Process clause incorporates all of the Bill of Rights, the Supreme Court supported selectively incorporating rights that the Court finds as essential to due process. Under selective incorporation, the Supreme Court incorporated certain parts of certain amendments, rather than incorporating an entire amendment at once.

Keep in mind that not all of the BOR are incorporated.
Hence the term Selective Incorporation.
