While nothing could possibly replace the Magna Carta's place in our hearts, the English Bill of Rights eventually replaced the Magna Carta in English law.

It turns out that in four hundred years some things had changed…and a medieval code of laws wasn't really cutting it anymore in the courtroom. (Maybe it was the fact that the serfs had been freed, or that the parliament now had more power than the monarchy.)

But even with the changes to better fit modern times there are still tons of carry-overs from that old piece of parchment that gave the world the idea that rights could be listed in the first place. (Source)
