As the number of Protestants in France increased, the number of heretics in prisons awaiting trial also grew. As an experimental approach to reduce the caseload in Normandy, a special court just for the trial of heretics was established in 1545 in the Parlement de Rouen. When Henry II took the throne in 1547, the persecution of Protestants grew and special courts for the trial of heretics were also established in the Parlement de Paris. These courts came to known as ""La Chambre Ardente"" ("the fiery chamber") because of their reputation of meting out death penalties on burning gallows.
