The main result of the Magna Carta, signed in 1215, was the establishment of the principle that the king's powers were not absolute and that he must govern according to the law. This charter laid the groundwork for the development of constitutional law and the eventual rise of parliamentary democracy in England. It introduced key concepts like due process, the right to a fair trial, and limited taxation without representation. The Magna Carta has since become a symbol of the fight against tyranny and the foundation for individual rights and freedoms in democratic societies.
