The Coronation... Fidei Defensor … Defender of the Faith: really...?
That phrase is quite possibly being hotly debated again as King Charles takes his Coronation oath. In fact, King Charles has signed up to it already and had it declared as one of his titles at his accession on the death of the late Queen.
Fidei Defensor is Latin for ‘Defender of the Faith’ and it is seen on all British coins in the abbreviated letters F.D. or FID. DEF. (I will leave others to do their own reading on the fate of the ‘Godless Florin’ of 1849 if your interest so inclines).
