What historical document was signed in 1215 limiting the power of the monarchy in England?

The document signed in 1215 that limited the power of the monarchy in England is the Magna Carta. This landmark agreement emerged from a conflict between King John of England and a group of rebellious barons. The Magna Carta is significant because it established the principle that everyone, including the king, was subject to the law, and it promised certain rights to the barons, such as protection from illegal imprisonment and access to swift justice. Over time, this document has come to symbolize the foundation of democratic principles, including the ideas of individual rights and the rule of law.

The other options, while important in their own contexts, do not fit the historical period or purpose of the Magna Carta. The Bill of Rights refers to amendments made to the U.S. Constitution, the Constitution is a foundational document for the system of governance in the United States established much later, and the Declaration of Independence is a statement asserting the independence of the thirteen American colonies from British rule, created in 1776. Each of these documents has its own historical significance, but they do not pertain to the events and implications surrounding the signing of the Magna Carta in 1215.
