The Anglo-French Empire was established by the Plantagenets, which dynasty has continued to rule (and which continues to use the Palace of Westminster as a royal residence, with Parliament far weaker than in our timeline). Richard I returned to England after being wounded at the siege of Chaluz, but recovered and ruled well, whilst John Lackland never held the throne and died in exile. Richard then went on to a decisive victory in the Anglo-French War which in our history King John lost. He dethroned the Capetian Dynasty and made himself and his successors Kings of France as well as of England, both kingdoms ruled from London, while Paris was left into the 20th century a provincial town, brooding over its lost glory. The Duchy of Normandy remained attached to the English crown and was never separated from it. Richard died in 1219 and was succeeded by his nephew Arthur whose reign was remembered as a Golden Age and sometimes confused in the popular imagination with that of King Arthur. Seven-hundred-fifty years later the present king is "John IV, by the Grace of God, King and Emperor of England, France, Scotland, Ireland the Anglo-French Empire, New England America, and New France America; Defender of the Faith, et cetera".
