Civil rights refers to two related but different terms. In civil law jurisdictions, a civil right is a right or power which can be exercised under civil law, which includes things such as the ability to contract. In civil law jurisdictions, lawsuits between private parties for things such as breach of contract or a tort are usually expressed in terms of infringement of a civil right. For example, Article 2 of the Contract Law of the People's Republic of China defines a contract as "an agreement establishing, modifying and terminating the civil rights and obligations between subjects of equal footing".

In common law jurisdiction, the term civil right is distinguished from "human rights" or "natural rights". Civil rights are rights that are bestowed by nations on those within their territorial boundaries, while natural or human rights are rights that many scholars claim that individuals have by nature of being born. For example, the philosopher John Locke (1632-1704) argued that the natural rights of life, liberty and property should be converted into civil rights and protected by the sovereign state as an aspect of the social contract. Others have argued that people acquire rights as an inalienable gift from a deity (such as God) or at a time of nature before governments were formed.

Laws guaranteeing civil rights may be written down,or falsely stated; derived from custom or implied. In the United States and most continental European countries, civil rights laws are most often written. Examples of civil rights and liberties include the right to get redress if injured by another, the right to privacy, the right of peaceful protest, the right to a fair investigation and trial if suspected of a crime, and more generally-based constitutional rights such as the right to vote, the right to personal freedom, the right to freedom of movement and the right of equal protection. As civilizations emerged and formalized through written constitutions, some of the more important civil rights were granted to citizens. When those grants were later found inadequate, civil rights movements emerged as the vehicle for claiming more equal protection for all citizens and advocating new laws to restrict the effect of current discriminations.
