Magna Carta Libertatum (Medieval Latin for "Great Charter of Freedoms"), commonly called Magna Carta (also Magna Charta; "Great Charter"): https://infogalactic.com/info/Magna_Carta
The Magna Carta created competition for the cabal's Roman Civil Law which they were imposing worldwide to allow human slavery, and we all know the cabal hates competition, especially when it puts a dent in their slave-trading profits.
In order to make you a slave, you must be converted into a "vessel" or cargo on a vessel or a strawman (fictitious entity) CORPORATION. This is what Admiralty jurisdiction allows (rules of the sea). All rights and privileges to engage in commerce are derived from the government or controlling authority and individual rights DO NOT EXIST. Humans are all property to be bought/sold/traded/fined/taxed as the "selected" rulers (CORPORATE OFFICERS) see fit. This is currently disguised as the Uniform Commerical Code (UCC) and this jurisdiction has been unconstitutionally imposed (violation of Article IV, Section 4) by the Federal Gov't onto the states of the Union via "National Emergency" of March 6, 1933. This is when they switched the jurisdiction.

Admiralty Law: https://infogalactic.com/info/Admiralty_law; Admiralty law is also known as CORPORATE Law, UCC, and Roman Civil Law (modern form originated in Rome, but likely goes back to Hammurabi of Babylon)
Article IV of the Constitution: https://www.law.cornell.edu/constitution/articleiv
Note that slavery includes involuntary servitude (general slavery), indentured servitude (to pay off debt owed), voluntary servitude (via contract), unknowing servitude (via contract), property servitude (a corporation or corporate gov't claims ownership of you)
Constitutional jurisdiction derived from the Magna Carta and the subsequent English Common Law prevents human slavery under all circumstances via Individual Rights derived from birth and life directly from God, not from the government. Also, one of its chief tenants is that individuals may own land in their own "natural person" capacity and does not allow strawmen (fictitious entities like CORPORATIONS). This is why the land jurisdiction is synonymous with Constitutional/Common Law and is joined to a "Republican Form of Government" guaranteed to the states of the Union by Article IV, Section 4 of the Constitution.
The original definition of "LIBERTY" is moving from the sea jurisdiction to the land jurisdiction or walking off a ship (vessel) via a port-of-entry (transition) onto the land that they own (freedom). One is "liberated" from the confines not just of the ship, but also from the restrictions of being "human cargo" under the control of the ship's captain (or admiral) per Admiralty "law of the sea".
L = land jurisdiction (Common law/property law)
A = air jurisdiction (Trust law/fictitious entity and organization creation law)
W = water jurisdiction (Admiralty law/commerce and trading of 'vessels' law)
The magna carta barons were the inheritors of a long tradition of ancient wisdom. Going back to Sumeria, if not Atlantis before that. The druid bardic system also kept this wisdom alive for a time.
I had read that even from the beginning there were factions of the Cabal that were humanist and factions that were anti-humanist. I guess Manga Carta barons were the humanists. Apparently, as centuries passed they went underground and whatever was left of them organized into what is now the Q plan.
