Why is the magna carta considered a source of traditional democratic principles

Explanation:

Issued by England's King John in June 1215, the Magna Carta was mainly an attempt to avoid civil war between the king and his barons. Magna Carta means in Latin "Great Charter". A charter is a document issued by the king or the queen which provides rights. This particular charter has more than sixty clauses about areas of the nation's life that included the right to a fair trial, the right to justice and the rights of individuals. The document has been considered a milestone in human history and democracy since it establishes that everyone is subject to the law, even the king -who signed the very same document, ensuring in that sense that no matter how powerful or powerless one could be, under the eyes of the law we are all seen the same.
