Answer:
I'll at least answer one of the questions for you, this one is for the Magna Carta one.
Step-by-step explanation:
The Magna Carta was provided in June of 1215, and the purpose was to put a stop to the king exploiting his power, and put limitations of authority by setting up law as a power on its own.
I'm sorry if any of this is confusing, as I tried my best.
