Jean IV, Count of Armagnac was the son of Constable Bernard VII of Armagnac, a victim of the Paris rebellion. We know that this prince, who had married Isabelle of Navarre, and had sworn fidelity to the King of England in 1421, followed a fluctuating diplomacy of which he was later the victim.

In the question of the Schism he supported Benedict XIII and then Clement VIII. Rebellious and submissive in turn, Jean IV was declared, on March 4, 1429, a schismatic, apostate, and placed under interdict.

After the renunciation of Clement VIII, Jean asked forgiveness of Martin V.
On March 4, 1430, he was relieved of the interdict and reëstablished in his dignities.

What motive incited him to consult Jeanne on such a tangled question as that of the legitimacy of the pope? Did he wish to color his change of attitude with a pious pretext?
