This biographical work explores the events that occurred in the life of English Catholic Jesuit priest Edmund Campion who was martyred by the government of Queen Elizabeth I. The writer aimed to present an accurate history and unknown facts about the priest from his youth to death. While running a secretive ministry in officially Anglican England, Campion was arrested by priest hunters. Condemned of high treason, he was hanged, drawn, and quartered at Tyburn. Pope Paul VI canonized him in 1970 as one of the Forty Martyrs of England and Wales. Campion's feast day is celebrated every 1st of December. Since one cannot separate the life of Campion from the time he lived, this work gives the readers a glance at the latter half of 16th century England.
