The Islands of Versilia wrote:What would be the Latin translation of “Free Britons”? I recall that many ancient civilisations referred to their people in their names, like Eranshahr being “Kingdom/Empire of Iranians”, or the “Regnum Romanorum”. I aim to use it in a nation name, being ICly titled the Kingdom of (Free) Britons in English.
That should be "Britanni liberi", I think.
