Knox composed this treatise on the occasion of the death of Edward VI, King of England. Catholic Queen Mary Tudor,
known to history as “Bloody Mary” succeeded him. In this work, Knox calls people to pray for Queen Mary, both for her wellbeing
and for her to uphold her promise not to persecute Protestants. Unfortunately, she did not uphold it, and Knox fled to continental
Europe for his life. Nevertheless, his prayers exhibit great maturity and compassion, and can serve to instruct Christians under tyranny.
