The rule of law (also known as nomocracy) is the legal principle that law should govern a nation, and not individual government officials. It primarily refers to the influence and authority of law within society, particularly as a constraint upon behavior, including behavior of government officials. The phrase can be traced back to the 16th century, and it was popularized in the 19th century by British jurist A. V. Dicey. The concept was familiar to ancient philosophers such as Aristotle, who wrote "Law should govern". Rule of law implies that every citizen is subject to the law, including law makers themselves. It stands in contrast to the idea that the ruler is above the law, for example bydivine right.
