Canonization of Joan of Arc
Path to sainthood
As with other saints who were excommunicated or investigated by ecclesiastic courts, such as Athanasius, Teresa of Ávila, and John of the Cross, Joan was put on trial by an Inquisitorial court. In her case, the court was influenced by the English, which occupied northern France, leading to her execution in the marketplace of Rouen. When the French retook Rouen in 1449, a series of investigations were launched. Her now-widowed mother Isabelle Romée and Joan's brothers Jéan and Pierre, who were with Joan at the Siege of Orléans, petitioned Pope Nicholas V to reopen her case. The formal appeal was conducted in 1455 by Jean Bréhal, Inquisitor-General of France, under the aegis of Pope Callixtus III. Isabelle addressed the opening session of the appellate trial at Notre Dame with an impassioned plea to clear her daughter's name. Joan was exonerated on 7 July 1456, with Bréhal's summary of case evidence describing her as a martyr who had been executed by a court which itself had violated Church law. In 1457, Callixtus excommunicated the now-deceased Bishop Pierre Cauchon for his persecution and condemnation of Joan.
