DEFENSOR FIDEI
defensor fidei (di-fen-s<<schwa>>r fI-dee-I), n.[Latin “defender of the faith”] Hist. A unique
title of the sovereign of England, first granted by Pope Leo X to Henry VIII for writing against
Martin Luther. • The Pope later withdrew the title because of Henry’s harsh regulation of the
church, but the title was again bestowed on the King by Parliament. The term is similar to the
application of “Catholic” to the Spanish sovereign and “Most Christian” to the French sovereign.
— Also termed Defender of the Faith. [Blacks Law 8th]
