The concept of a natural law establishing

The concept of a natural law establishing the existence of specific natural rights first appeared in ancient Greek philosophy and was referred to by Roman philosopher Cicero. It was later referred to in the Bible and further developed during the Middle Ages. Natural rights were cited during the Age of Enlightenment to oppose Absolutism— the divine right of kings.
Today, some philosophers and political scientists contend that human rights are synonymous with natural rights. Others prefer to keep the terms separate in order to avoid the mistaken association of the aspects of human rights not typically applied to natural rights. For example, natural rights are considered to be beyond the powers of human governments to deny or protect.
