When was Magna Carta written?
Magna Carta (Latin, “Great Charter”), document sealed by King John of England on June 15, 1215, in which he made a series of promises to his subjects that he would govern England and deal with his vassals according to the customs of feudal law . It has since been considered the basis of English constitutional liberties (as well as those of countries influenced by English tradition) and a key event in the history of medieval Britain.
