In October 1307 all the brothers of the military religious Order of the Temple in France were arrested on the instructions of King Philip IV and charged with heresy. In November, Pope Clement V instructed King Edward II of England to do likewise. These two volumes provide the first full edition and translation of the four surviving texts of the trial proceedings that followed in Britain and Ireland. Detailed introductions to each volume describe the manuscripts and how the material was compiled and arranged, and discuss the course of the proceedings and the value of the evidence they contain.
