Did You Know?

A signatory puts his or her signature on a document that is also signed by others. In 1215 the English barons revolted against King John and forced him to join them as a signatory to the Magna Carta. This agreement stated the barons' own duties to the King but also assigned the barons clear rights and limited the King's power over them. Though the Magna Carta did nothing for the common people, it's often been called the first step toward democracy in the English-speaking countries.
