It is Hollywoodized image of one of the last kings of the Crusader Kingdoms,
Baldwin IV of Jerusalem, also known as "the Leper King." I generally tend to keep my politics off the board, but I feel Western Civilization is going to the same way as these kingdoms did, sometime in the next century or two. So that part is apropos re: my feelings on that matter.
The image itself is some sort of screenshot from the movie
Kingdom of Heaven. Which I haven't actually seen yet, but plan to.
There's actually no historical evidence pointing towards Baldwin ever having worn a mask, but, meh, its a cool picture.
