Answer:
Magna Carta
Step-by-step explanation:
The Magna Carta was a charter of rights agreed to by King John of England in 1215. The document established some limitations to the power of the monarch, such as the protection of church rights, protection from illegal imprisonment, and access to justice. After William and Mary ascended to the throne of England, Parliament insisted that their new monarchs respected this document, as it was considered the foundation of English law.
