During her two and one-half year reign, Mary I had nearly three hundred people burned at the stake, the most famous of which may have been Archbishop of Canterbury, Thomas Cranmer, who died on this date in 1556. Mary also arranged the beheading of her predecessor, Jane. The sobriquet "Bloody Mary" certainly seems apt. It may be argued that she was not, in fact, a cruel person, but rather reigned within the law to the good of the people, and within her conscience to the good of her eternal soul.
And actually, there is an apologist for most any person or any act. The human condition itself is depraved.
Thomas Cranmer 2 July 1489 – 21 March 1556
