What was the primary consequence of the Magna Carta signed by King John?

The Magna Carta, signed in 1215, primarily served to limit the powers of the king and establish a framework for the protection of certain rights for the nobility and, by extension, other subjects. Specifically, this historic document required King John to respect a variety of legal rights, including the rights to due process and a fair trial, thereby setting a precedent for the idea that the monarchy was not above the law. The Magna Carta is often seen as a foundational step toward establishing constitutional governance and more extensive legal rights within England, influencing future legal systems both in England and around the globe.

The context of the Magna Carta also reveals its significance in contrast to other options. It did not limit the power of the nobility in the sense of suppressing their rights or freedoms; instead, it was primarily a safeguard for the barons against the king's arbitrary rule. Furthermore, it did not establish an absolute monarchy, as one of its key principles was to limit the king's powers. Lastly, the Magna Carta did not address issues of serfdom, as it was focused more on the rights of nobles and governance rather than labor systems prevalent at the time.
