William Laud.

'The Lord receive my soul, and have mercy on me, and bless this kingdom with peace and charity, that there may not be this effusion of Christian blood amongst them.' William Laud  -  disgracefully and shamefully executed by the parliamentary faction at the time of The English Civil War. (And, no. I have precious little sympathy for the fate meted out to that egregious shedder of innocent blood, Charles The First, who met a similar and considerably more justifiable end.)
