The Magna Carta, 1215

In 1215, after King John of England violated a number of ancient laws and customs by which England had been governed, his subjects forced him to sign the Magna Carta, which enumerates … rights. Among them was the right of the church to be free from governmental interference, the rights of all free citizens to own and inherit property and to be protected from excessive taxes … the right of widows who owned property to choose not to remarry, and established principles of due process and equality before the law. It also contained provisions forbidding bribery and official misconduct.

Widely viewed as one of the most important legal documents in the development of modern democracy, the Magna Carta was a crucial turning point in the struggle to establish freedom.
