Explanation:
The Universal Declaration of Human Rights (UDHR) is a declaratory document adopted by the General Assembly of the United Nations in its Resolution 217 A (III), on December 10, 1948 in Paris; in this 30 human rights considered basic are collected in its 30 articles, from the letter of San Francisco (June 26, 1945). The union of this declaration and the International Covenants on Human Rights and its protocols includes what has been called the International Charter of Human Rights. While the Declaration generally constitutes an orientation document, the Covenants are international treaties that oblige the signatory States to comply with them.
In the slow evolution of rights in history, it is from the seventeenth century when explicit statements begin to be contemplated based on the contemporary idea of "natural law." In 1679, England incorporated the Habeas Corpus Act and the Bill of Rights (Bill of Rights) in 1689 into its constitution in 1689. In France as a result of the French Revolution, the Declaration of Rights of Man and Citizen.
In 1927, the Slavery Convention of 1926 enters into force, which prohibits slavery in all its forms. The so-called "Mechelen Codes" that cover international morals (1937), social relations (1927), family relations (1951) and the Code of Political Morals (1957), are partial attempts by the public conscience to regulate security minimum respect for the individual, usually ignored by the states. As a result of World War I, the League of Nations promoted the Geneva Conventions on security, respect and minimum rights of prisoners of war, and in 1948 after World War II, the United Nations General Assembly approved the document entitled “ Universal Declaration of Human Rights ”, set of rules and principles, guarantee of the person against public authorities.
