The Manga Carta (The Great Charter) is the one of most signifigant pieces of histroy. It recongizes 4 basic humans rights:
(1) No taxes may be levied without consent of Parliament
(2) No subject may be imprisoned without cause shown (reaffirmation of the right of habeas corpus)
(3) No soldiers may be quartered upon the citizenry
(4) Martial law may not be used in time of peace.
These values are still reflected in today's societies and have become the basics of human rights as we know it.
