How did the Magna Carta and English Bill of Rights limit the power of the Monarchy?

well the magna carta was signed in 1215 by king john of England this document protected the authority and privilege of the nobility against the absolute power of the king. it limited the kings rights to arbitrarily tax and seize people or their property, the document applied to all "freemen", granting them certain protections.

now the Bill of Rights set out in detail the rights of individual citizens

so to answer your question the connection between them is that they are both documents that were signed for the protection and rights of the citizens the Bill of Rights just put it in more detail. hope this helped :)
