Byzantium: no feudalism + 12th century renaissance
Britain: Magna Carta (1215)
France: Philippe le bel (1268 – 1314): created Parlement & États-Généraux

British copied the Byzantines while defaming them.
French copied the British while defaming them.

The reason why the British didn’t have a “French revolution” is cause they didn’t have divine-right monarchy to begin with. The reason why Byzantines didn’t have Magna Carta is they didn’t have western feudalism to begin with. Greek language & culture was normative.

Orthodox byzantine church took official decisions through councils. No need for Magna Carta. The idea of a single Pope controlling the Church was shocking, heretic, ridiculous, hubris, against the teachings of Christ, against the normative greek culture…. thus, the schism.
