Description
Ar 15 Mehefin 1215, gorfodwyd y Brenin John i gyfarfod â’i farwniaid gwrthryfelgar yn Runnymede. Oherwydd eu diffyg ffydd ynddo, gorfodwyd y brenin i arwyddo siarter a baratowyd ganddynt. Hwn oedd y Magna Carta, dogfen chwyldroadol a heriodd awdurdod brenhinol mewn modd nas gwelwyd erioed o’r blaen.On 15 June 1215, rebel barons forced King John to meet them at Runnymede. They did not trust the King, so he was not allowed to leave until his seal was attached to the charter in front of him. This was Magna Carta. It was a revolutionary document. Never before had royal authority been so fundamentally challenged.
