Step-by-step explanation:
The Magna Carta and the Petition of Right
The two documents that limited the power of the monarchy are the Magna Carta and the Petition of Right. The Magna Carta, signed in 1215, established the relationship between the king and the nobles in England, and established guarantees such as trial by jury and due process for the nobles. The Petition of Right, written in 1628, extended the rights of 'commoners' to have a voice in the government.
