Thomas Cranmer was a theologian, leader of the English Reformation and Archbishop of Canterbury during the reigns of Henry VIII, Edward VI and, for a short time, Mary I. He is honoured as a martyr in the Church of England.

A martyr is someone who suffers persecution and death for advocating, renouncing, or refusing to renounce or advocate, a religious belief or other cause as demanded by an external party. In colloquial usage, the term can also refer to any person who suffers a significant consequence in protest or support of a cause.
