Civil liberties in the United States

Civil liberties in the United States are certain unalienable rights retained by (as opposed to privileges granted to) citizens of the United States under the Constitution of the United States, as interpreted and clarified by the Supreme Court of the United States and lower federal courts.[1] Civil liberties are simply defined as individual legal and constitutional protections from entities more powerful than an individual, for example, parts of the government, other individuals, or corporations. The explicitly defined liberties make up the Bill of Rights, including freedom of speech, the right to bear arms, and the right to privacy.[2] There are also many liberties of people not defined in the Constitution, as stated in the Ninth Amendment: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

The extent of civil liberties and the percentage of the population of the United States who had access to these liberties has expanded over time. For example, the Constitution did not originally define who was eligible to vote, allowing each state to determine who was eligible. In the early history of the U.S., most states allowed only white male adult property owners to vote (about 6% of the population).[3][4][5] The Bill of Rights had little impact on judgements by the courts for the first 130 years after ratification.[6]
