Civil rights are often confused with civil liberties, which is an overriding legal contract that guarantees the freedom of citizens or residents of a country, such as the US Bill of Rights, and is interpreted by courts and legislators. The right to freedom of expression in the First Amendment is an example of civil liberties. Both civil rights and civil liberties are subtly different from human rights, which belong to all, no matter where they live, such as freedom from slavery, torture and religious persecution. In fact, all countries reject certain civil rights of certain minorities through laws or customs. For example, in the United States, women continue to face discrimination traditionally in men’s work. Although the Universal Declaration of Human Rights, adopted by the United Nations in 1948, embodied civil rights, these provisions were not legally binding. Therefore, there is no global standard. On the contrary, individual countries often react differently to the pressure to develop civil rights laws. Historically, when a large proportion of people in a country feel unfairly treated, civil rights movements will emerge. Although in most cases it is related to the American civil rights movement, similar significant efforts have taken place elsewhere.
