The correct answer is 2. it established the legal principle that the monarch was not above the law.

The Magna Carta, also known as the Great Charter, was a document signed by King John of England in 1215. It was a crucial development in the establishment of constitutional monarchy because it limited the power of the monarch and established that they were subject to the law, just like any other citizen. It laid the foundation for the idea that the rights and liberties of individuals should be protected by the law and that the monarch's authority should be bound by legal limits. This principle of the rule of law became a cornerstone of constitutional monarchy, ensuring that monarchs could not act arbitrarily or violate the rights of their subjects.
